VITA Specifications
The VME family of specifications has grown significantly since its inception. VMEbus has expanded from the original family of a core VME32 parallel bus specification, a VME Subsystem bus, and a VME serial interconnect to today's broad family of complementary state-of-the art specifications.
As the serial switch fabric solutions that include Ethernet, PCI Express, RapidIO, Infiniband and other alternatives gain popularity and additional usage to form critical mass in the industry, specific purpose parallel and serial subsystem buses will start sharing market space by solving different problems within tomorrow's embedded systems. VITA is evolving to incorporate the appropriate alternatives.
VITA Technology includes several mezzanine specifications that have been optimized for use in critical embedded system environments. Low profile, small form factor mezzanine solutions of various types have been developed with several obtaining ANSI approval. IP modules, M-modules, PC*MIP, FMC, and the very popular PMC modules all work effectively in critical embedded system applications, evolving as technology and application needs change.
Several system management and support specifications have also been ratified that make the development of systems easier with more robust system management. Proposals continue to be submitted and considered for addition to the VITA Technology family to improve utilization in complex systems.
VITA is also involved in activities to enhance reliability prediction and certification standards as it relates to electronic modules. The Reliability Prediction Community is leading the efforts to improve the tools available to designers.
The specifications database has a complete listing of the many specifications along with their current status.

Common Name | Description | Status |
|---|---|---|---|
| ANSI/VITA 1.0-1994 (S2011) | VME64 | The VME64 specification establishes a framework for 8-, 16-, 32, and 64-bit parallel-bus computer architectures that can implement single and multiprocessor systems. This bus includes the initial four basic sub-buses: (1) data transfer bus, (2) priority interrupt bus, (3) arbitration bus, and (4) utility bus. The data transfer bus supports 8-, 16-, 32-, and 64-bit data transfers in multiplexed and non multiplexed form. The transfer protocols are asynchronous with varying degrees of handshaking dependent on the speeds required. The priority interrupt subsystem provides real-time interrupt services to the system. The allocation of bus mastership is performed by the arbitration subsystem which allows the implementation of several prioritization algorithms. The utility bus provides the system with power plus power-up and power-down synchronization. The mechanical specifications of boards, backplanes, subracks, and enclosures are based on IEC 297 and IEEE 1101.1 specifications, also known as the Eurocard form factor. Additional standards exist that can be used as sub-busses to this architecture for data transfer transactions, peripheral interfaces and intra-crate communications among compatible modules. | ANSI Stabilized |
| ANSI/VITA 1.1-1997 (S2011) | VME64x Extensions | This specification is an extension of the ANSI/VITA 1-1994, VME64 specification. It defines a set of features that can be added to VME32 and VME64 boards, backplanes and subracks. These features include a 160 pin connector, a P0 connector, geographical addressing, voltages pins for 3.3V, a test and maintenance bus, and EMI, ESD, and front panel keying per IEEE 1101.10. | ANSI Stabilized |
| ANSI/VITA 1.3-1997 (S2011) | VME64x 9U x 400 mm Format | This specification is an extension of the ANSI/VITA 1-1994, VME64 specification. It defines 9U x 400 mm boards, backplanes and subracks. The VME64x specification expands the features of VME64 mainly by using a different 160 pin connector. These and other features in the VME64x standard gained the interest of the Telecommunications Industry and the Physics Research Community. A major concern in both groups was a larger board format yet keeping as much compatibility with the existing VME standards as possible. This standard is a response to these needs. |
ANSI Stabilized |
| ANSI/VITA 1.5-2003 (R2009) | VME 2eSST | This specification is an extension of the ANSI/VITA 1-1994, VME64 and ANSI/VITA1.1-1997, VME64x specifications. It defines a transfer protocol, based upon source synchronous concepts, that permits the VMEbus to operate at rates to at least 320MB/s. As technology improves, this rate can be extended to higher levels. The 2eSST protocol requires low skew between signals and monotonic rising and falling edges on the signals. To meet these requirements, limited length backplanes, special backplane topologies and/or enhanced transceivers are required. The specification calls for enhanced bus transceivers with controlled rise and fall times, tightly defined thresholds, low part to part skew and LVTTL levels. During the development of this standard, specific transceivers were developed to meet these requirements. |

| ANSI/VITA 1.6-2000 (S2011) | Keying for Conduction-cooled VME64x | This specification is an extension of the ANSI/VITA 1.1-1997, VME64x specification. It defines an alternate keying system that can be added to VME64x boards and backplanes in a conduction cooled environment (IEEE 1101.2) where keying as defined in the VME64 Extensions standard cannot be applied. | ANSI Stabilized |
| ANSI/VITA 1.7-2003 (R2009) | Increased Connector Current Level | The P1/J1 and P2/J2 current rating limits of the 3 row DIN and 5 row DIN connector pins listed in the DIN41612, IEC 603-2 and 61076-4-113 specifications are based on full loading of the connector. In VME, VME64, and VME64 Extensions applications, the power pins represent only a small fraction of the total number of pins and are spread throughout the connector. The remaining pins are used to carry electrical signals, which add a negligible heating contribution. The net effect is that the connector heating is less, which allows a higher current carrying capacity. Power contacts of connectors tested and certified in accordance with this standard are capable of passing 2.0 amps per contact on a selected group of pins. The standard has been verified by testing connectors from multiple vendors and it has been developed and approved by a broad cross-section of the VMEbus community. |

| ANSI/VITA 3-1995 (S2011) | Board Level Live Insertion | This specification identifies methodologies through which a faulty board can be removed from a system and a replacement board can be inserted while the system continues to operate. The primary motivation for supporting Board Level Live Insertion within the VMEbus environment is to enhance the current VMEbus standard while maximizing the use of existing off-the-shelf VMEbus products. | ANSI Stabilized |
| ANSI/VITA 4.0-1995 (S2011) | IP Modules | This specification defines a versatile module, known as an "IP module." These modules provide a convenient method of implementing a wide range of I/O, control, interface, slave processor, analog and digital functions. IP modules, about the size of a traditional business card, mount parallel with a host Carrier board, which provides host processor or primary bus interfacing, as well as mechanical means for connecting the IP module's I/O to the outside world. Typical Carriers include standalone processors, DSP based carriers, as well as desktop buses and VME based boards. This specification includes mechanical, host bus electrical, and logical definition of I/O space, memory space, identification space, interrupts, DMA, and reset functions. Two physical sizes, two fixed clock rates, and multiple data width sizes to 32-bits are defined. | ANSI Stabilized |
| ANSI/VITA 4.1-1996 (S2011) | IP I/O Mapping to VME64x | With the development of the VME64x, 205 user defined I/O pin are available for rear backplane I/O. It is practical to route multiple IP's I/O through the VME64x backplanes. This standard defines the mapping of the 50 user defined I/O pins from the IP module (ANSI/VITA 4-1995 (R2002)) I/O connectors to VME64x board's rear I/O connectors in a consistent method across all VME64x boards, backplanes and rear I/O transition boards. | ANSI Stabilized |
| ANSI/VITA 5.1-1999 (S2011) | RACEway Interlink on VME | This specification provides a definition of the data link protocol and physical interface of a high performance extension to the VMEbus specification. This extension consists of high bandwidth, low latency interconnects across a VMEbus computer chassis backplane using the P2 connector. Bi-directional connectivity between boards in a VMEbus chassis is achieved through the use of a network of crossbar switches with point-to-point interconnects. RACEway Interlink is a VMEbus enhancement that can deliver up to 3.2 Gbytes/sec of scalable bandwidth over rows A, C, D and Z of the P2 connector in a standard VMEbus chassis. In addition to increased bandwidth, RACEway Interlink offers: 1) low latency, deterministic transactions, 2) concurrent point-to-point transactions for multiple simultaneous transfers, and 3) scalable bandwidth so total bandwidth increases as more slots are added. Many new applications, especially those with multiple processors and multiple real-time I/O interconnects, require these capabilities. | ANSI Stabilized |
| ANSI/VITA 6.0-1994 (S2011) | Signal Computing System Architecture (SCSA) on VME | The Signal Computing System Architecture (SCSA) specification establishes a framework for the inter- and intra-system transfer of serial media data and control information oriented toward the development of high density call and voice processing products and systems. The SCSA architecture is application specific and is embodied as a family of buses that are defined in this physical layer of the specification to reside on the VMEbus J2/P2 connector. The SCSA buses coexist with products compliant with ANSI/VITA 1-1994, VME64. SCSA at the physical level consists of two separate subbuses, a sixteen line, TDM data transfer bus called the SCbus, and a serial, peer-to-peer communication link called the SCmessage bus. The primary purpose of the SCbus is to support the exchange of real time telephonic voice, facsimile, data, video and other media streams. The purpose of the SCmessage bus is to transport interprocess control and status messages. This specification defines only the physical and data link OSI layers of the eventual four layer transport facility. The SC data transport bus is a synchronous, byte-serial, continuously framed bus organized as 16 serial data paths each divided into 32, 64, or 128 eight bit timeslots with a frame rate of 8,000 per second in order to accommodate intra-system telephonic voice and data transfers. The message bus is an HDLC framed, 2 Mbps, CSMA/CD packet bus that is bit-synchronized with the data transport bus. This specification covers the hardware specific elements of the VME-SCSA subbus including the message bus OSI protocol layers 1 and 2. Subsequent specifications provide an interface definition for the device specific software layer that provides compatibility between compliant VME-SCSA products and available upper layer SCSA resource management application programming interface(api) and other application software. |

| ANSI/VITA 10-1995 | SKYchannel Packet Bus on VME | This specification describes a high performance SKYchannel Packet Bus architecture that is fully compatible with the VMEbus standards. This standard addresses communication between VME boards using the P2 connector. This includes the physical layer for communication between the VME board and a SKYchannel Backplane through VME P2/J2, and the data link layer for communication from board to board. This specification does not address the physical layer for running SKYchannel within a SKYchannel Backplane or group of Backplanes, which is considered an implementation detail. The specification includes specifics of the packet protocol, signals, waveforms, timing diagrams and mechanical specifications. |
ANSI Stabilized |
| ANSI/VITA 12-1997 (S2012) | M-Module | This specification defines minimum mechanical and electrical characteristics of M-Modules, a method of implementing modular circuit boards with specific functions that can be used to add functionality to other larger printed circuit boards. For special requirements, a third row can be added to the base board connection. This is described in the mechanical specification. The use of the additional signals or extended use of existing signals (in compliance with the basic electrical specification) can be standardized to a certain extent. Therefore, certain signals and signal groups are defined in the extended electrical specification as regards their function, timing and electrical characteristics. Modules complying with these additional specifications are designated MA-Modules. |

| ANSI/VITA 17.0-1998 (S2011) | Front Panel Data Port (FPDP) | This extension to the VME specification consists of a multi-drop synchronous parallel non-addressable bus connection between multiple boards in a single chassis. The connection is made to a connector on the front panel of each board by means of an eighty conductor ribbon cable. The purpose of this specification is to allow products to be designed to work with other FPDP products. The degree of interoperability may depend on the layers of functionality above the physical and data link layers. These higher layers are not part of this specification. | ANSI Stabilized |
| ANSI/VITA 17.1-2003 (R2009) | Serial Front Panel Data Port | As the name implies, it is directly related to the Front Panel Data Port (FPDP) specification, deriving its serial protocol from the defined protocol and control signals of FPDP. This Serial FPDP specification supports three link speeds: 1.0625 Gbaud, 2.125 Gbaud, and 2.5 Gbaud. These three link speeds can support data transfer rates in excess of 105 MBps, 210 MBps, and 247 MBps respectively. Included in this definition are the data frame structure, the link layer protocol, and the physical media requirements. The purpose of this specification is to allow products to be designed to work with other Serial FPDP products. The degree of interoperability will depend on the specific options implemented. Although all options are supported by this standard, not all products are required to support all options. |
ANSI Ratified |
| VITA 17.2 | Serial Front Panel Data Port (SFPDP) Channel Bonded Protocol | The main objective of VITA 17.2 is to increase the bandwidth of the link. This can be done by both increasing the speed of the link, and by providing the ability to channel bonding several lanes together. The VITA 17.2 protocol is designed to provide functional compatibility with both VITA 17 and VITA 17.1 protocols, while providing increased bandwidth. In addition, the VITA 17.2 protocol is designed to provide a minimum footprint, and to maximize the use of dedicated hardware that is found in current FPGAs. |

The VMEbus standards are the basis for this document. Hardware and software produced according to this document are in full compliance with the VMEbus standards. The Rules, Recommendations, Observations, etc. in this document are complementary to and compliant with existing VME standards. The Rules in this document are based on either Rules, Recommendations or Suggestions in a VME standard or draft standard as well as items not addressed by VME standards. This document is generally consistent with the NIM/VME-P document 9612, "VMEbus for Physics Applications", that has served as a working group approach, and has also utilized items from the CERN VSC "Recommended Practices" document. | ANSI Stabilized |
| ANSI/VITA 26-1998 (S2011) | Myrinet on VME Protocol | This specification describes the high-performance, inter-computer, Myrinet packet network that is fully compatible with existing VMEbus specification and their extensions. This specification addresses communication between VME boards using interconnect either on the front panel or on the backplane. The communication may use cables or an overlay (such as a backplane). The specification defines the interface between a VME board and Myrinet, allowing not only intra-subrack, board-to-board communication, but also a uniform extension for inter-subrack, inter-cabinet, and even local-area-network (LAN) communication. This standard includes, either directly or by reference, the specification of the Data Link level, timing information, character set, signals, and the details of the connectors. | ANSI Stabilized |

| ANSI/VITA 30.0-2000 (S2011) | 2mm Connector Practice for Eurocard Systems | This document defines an equipment practice based on a combination of 2 mm connectors, per IEC 61076-4-101, and subracks, racks and printed boards based on the Euroboard form factors. In the late 1980's, the VME specification expanded for 64 bit data and address capability, which also affected the specified connectors used at the plug-in module interface. The designers utilized IEC 61076-4-101 2 mm based connectors to increase connector pin counts and to facilitate the adoption of certain architectural features and capabilities. Physical features required to incorporate these connectors into the IEEE 1101.1 and IEC 60603-2 based architecture were detailed in the individual specifications. This document provides a means to specify this information without including extensive details in the systems specifications. The combination of Euroboard form factors and 2 mm connectors has been utilized in other system architectures and is anticipated to be included in future systems. This specification defines a variety of configurations that combine Euroboards and 2 mm connectors in a manner that facilitates references to such architecture in such current and future applications. |

| ANSI/VITA 30.1-2002 | 2mm Connector Practice for Conduction Cooled Euroboards | This specification is intended to be a companion specification to other standards as referenced. Other uses for this specification are in no way prohibited. The aim is to ensure mechanical interchangeability of conduction-cooled circuit card assemblies in a format suitable for military and rugged applications and to ensure their compatibility with both conduction cooled chassis and commercial, air-cooled, single height (3U) and double-height (6U) x 160mm, Euroboard chassis. | ANSI Ratified |
| VITA 30.2-2001 (IEC) | Power Connector Equipment Practice | This document describes various separable connectors that can be used to conduct electrical current between two printed boards. Typical applications include power supplies or other power management devices. It has been developed to aid in the design of equipment where such connectors are typically found. The information included consists of interface and profile dimensions, printed board layout dimensions, suggested or actual signal and power pin assignments as well as information regarding standards that may exist for the connectors. No consideration is given to current carrying capacities of the connector systems nor to the optimization or validity of any pin assignment schemes, which may be included. Similarly, if connector locations are given relative to common industry board practices, they are not to be assumed to be the sole possible location of such connectors. Power connectors are defined, for the purpose of this standard, as separable connectors that are designed to provide current to devices at levels consistent with the overall operating power of the device. As such, they must have at least one (1) contact capable of carrying five (5) amps or more of electrical current. | Industry Technical Agreement |
| ANSI/VITA 31.1-2003 (R2009) | Gigabit Ethernet on VME64x Backplanes | This specification leverages the PICMG 2.16 packet Switched backplane specification that adds a switched network based on Gigabit Ethernet to CompactPCI backplanes. The PICMG 2.16 CompactPCI P3 connector has two Gigabit Ethernet ports for improved performance and redundancy. The CompactPCI P3 connector and the VME64x P0 connector are identical IEC 61076-4-101 2 mm based connectors and have the same placement on the backplane. This standard adopts the PICMG 2.16 P3 connector pin assignment for use on VME64x boards. This standard also adopts the definition of the fabric card described in PICMG 2.16. PICMG 2.16 compliant systems and VITA 31.1 systems can use the same switched fabric boards. | ANSI Ratified |
| ANSI/VITA 32-2003 (R2009) | Processor PMC | The complete physical (mechanical) and the environmental layers are retained as specified in the IEEE 1386 CMC ("Common Mezzanine Card") standard except as noted in this document. If the information in this document contradicts IEEE 1386 or IEEE 1386.1, this document takes precedence. Processor PMC cards are used where modular attachment of a processor is desired. These processor PMC cards may be used in conjunction with PMC I/O cards, traditional PCI cards, or with directly attached PCI components. As such, Processor PMCs increase the modularity of a computer system and thus complement, rather than compete with, the existing family of PMC cards. Processor PMC cards are expected to electrically operate with existing carrier boards (or motherboards); that is, while the carrier may be redesigned to take advantage of the enhanced functions that are offered by this standard, such a redesign should not be a requirement to insure proper operation. Indeed, Processor PMCs shall be specifically enabled to operate as master/host CPUs; otherwise, such cards revert to traditional PMC modes, operating as intelligent slave/target processor boards.when that support is required within PMC and Processor PMC designs. |

This document describes a service indicator standard that seeks to be as compatible as possible with existing indicator standards and their extensions across different product markets. This standard addresses the meaning and application of specific colors to service indicators. This standard also defines and assigns meanings to specific approved behaviors or states for each color. It specifies where indicators must be placed and in what order, and it specifies luminance levels and viewing angles. |

| ANSI/VITA 41.0-2006 (R2011) | VXS: VMEbus Switched Serial Base Specification | The VME Switched Serial (VXS) specification comprises this base standard defining physical features of VXS components, coupled with a set of protocol layer standards to define the specific serial interconnect used in a system implementation. The VXS base specification defines physical features that enable high-speed communication in a VME compatible system. These features include: addition of a high speed connector to the VME64x board in the P0/J0 position, a 6U by 160mm by 6HP Eurocard format board with many high speed connectors which may act as a switch, and the backplane/chassis infrastructure needed to support these features. In addition to defining a high -speed connector in the P0/J0 area, VXS also defines alignment and keying features which may be used to protect this and future alternate connectors. The ratio of one high-speed connector per payload board to many on the switch card lends itself to a star topology where each payload card is connected to a central switch. For higher reliability and/or load balancing, two switch cards may be used in a dual star configuration. Interswitch links may be included for reliability and load balancing reasons as well. Although this topology is not required it is a natural fit for the system features. |

Interfaces defined in this specification include the following: - Ethernet: 10/100/1000 BaseTX MDI ports - USB: 1.1 and 2.0 ports - RS-232 / RS-485 serial ports - Serial ATA / Fibre Channel / SAS ports Other interface ports, such as I2C serial links or video ports, may also be carried on the XMC secondary connectors. The system designer is responsible for managing signal assignments for those ports, as those assignments are outside the scope of this specification. |
