ANSI/VITA 1.0-1994 (S2011)

VMEbus or VME64

The VME64 standard 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 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/VITA 1.1-1997 (S2011) VME64x Extensions VME64x is an extension of the ANSI/VITA 1-1994, VME64 standard. 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 standard defines a 9U x 400 mm board layout for use within the VMEbus framework.

ANSI Stabilized
ANSI/VITA 1.5-2003 (S2014) VME 2eSST An extension of the ANSI/VITA 1-1994, VME64 and ANSI/VITA1.1-1997, VME64x standards. It defines a transfer protocol, based upon source synchronous concepts that permit the VMEbus signalling  to operate at rates to at least 320MB/s. 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 standard calls for enhanced bus transceivers with controlled rise and fall times, tightly defined thresholds, low part-to-part skew and LVTTL levels. ANSI Stabilized 
ANSI/VITA 1.6-2000 (S2011) Keying for Conduction-cooled VME64x An extension of the ANSI/VITA 1.1-1997, VME64x standard. 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 (S2014) 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 standards 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 Stabilized 
ANSI/VITA 3-1995 (S2011) Board Level Live Insertion This standard 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 4-1995 (S2011) IP Modules This standard 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 standard provides a definition of the data link protocol and physical interface of a high performance extension to the VMEbus standard. 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 6-1994 (S2011) Signal Computing System Architecture (SCSA) on VME The Signal Computing System Architecture (SCSA) standard 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 four layer transport facility. ANSI Stabilized

ANSI Stabilized 
ANSI/VITA 17-1998 (S2011) Front Panel Data Port (FPDP) This standard defines a point to point data interconnect for use on front panel Eurocard modules. FPDP consists of a multi-drop synchronous parallel non-addressable bus link between multiple boards in a single chassis. The link is made to a connector on the front panel of each board by means of an eighty conductor ribbon cable. The purpose of this standard 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 standard. ANSI Stabilized 
ANSI/VITA 17.1-2015 Serial Front Panel Data Port (sFPDP) Serial FPDP (sFPDP) is directly related to the FPDP standard, deriving its serial protocol from the defined protocol and control signals of FPDP. The Serial FPDP standard supports seven link speeds: 1.0625, 2.125, 2.5, 4.25, 5.0, 8.5, and 10.0 Gbaud. These seven link speeds can support data transfer rates in excess of 105 MBps, 210 MBps, 247 MBps, 420 MBps, 494 MBps, 840 MBps, and 988 MBps respectively. Included in this definition are the data frame structure, the link layer protocol, and the physical media requirements. 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 bond 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.

ANSI/VITA 30-2000 (S2011) 2mm Connector Practice for Eurocard Systems 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 30.1-2008 (R2014) 2mm Connector Practice for Conduction Cooled Euroboards This standard 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 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 (S2014) Gigabit Ethernet on VME64x Backplanes This standard 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 Stabilized
ANSI/VITA 32-2003 (S2014) 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.

ANSI/VITA 41.0-2006 (R2011) VXS: VMEbus Switched Serial Base The VME Switched Serial (VXS) standards 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 standard 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.
