In this article, we will explain what PICMG 2.0 R3.0 specification is, what are its main features, and what are its benefits for industrial computing applications.


What is PICMG 2.0 R3.0 specification?




PICMG stands for PCI Industrial Computer Manufacturers Group, a consortium of companies that develops open standards for industrial computing platforms. PICMG 2.0 is one of the most widely used standards for CompactPCI systems, which are based on the PCI bus architecture.


CompactPCI systems consist of a backplane that provides power and data connections, and a number of plug-in modules that perform different functions, such as CPU, memory, storage, I/O, etc.


PICMG 2.0 R3.0 is the latest revision of the CompactPCI Core Specification, which was introduced in late 1999. It incorporates several enhancements and extensions to the previous versions, such as hot swap and computer telephony specifications, pin sequencing and shrouding, metric ERmet connectors, and various backplane variants.


What are the main features of PICMG 2.0 R3.0 specification?




Hot swap and computer telephony specifications




One of the main features of PICMG 2.0 R3.0 specification is the support for hot swap and computer telephony applications.


Hot swap refers to the ability to insert or remove modules from a CompactPCI system without shutting down or disrupting its operation. This allows for easy maintenance, upgrade, or replacement of faulty components.


Computer telephony refers to the integration of voice and data communication over a single network. This enables CompactPCI systems to provide services such as voice over IP (VoIP), interactive voice response (IVR), call center management, etc.


Pin sequencing and shrouding




Another feature of PICMG 2.0 R3.0 specification is the introduction of pin sequencing and shrouding for CompactPCI connectors.


Pin sequencing is a technique that ensures that certain pins on a connector make contact before others during insertion or removal of a module. This prevents damage or malfunction due to electrical transients or short circuits.


Shrouding is a technique that provides shielding and protection for the pins on a connector from external interference or accidental contact.


Metric ERmet connectors




A third feature of PICMG 2.0 R3.0 specification is the use of metric ERmet connectors for CompactPCI systems.


ERmet connectors are high-density connectors that comply with the IEC 61076-4-101 standard. They are available in four build types: A, B, AB, and monoblock. They offer high performance, reliability, and flexibility for CompactPCI applications.


CompactPCI backplane variants




A fourth feature of PICMG 2.0 R3.0 specification is the definition of various backplane variants for CompactPCI systems.


Backplanes are the main boards that provide power and data connections for the plug-in modules. They can have different installation heights, system slots, power supply options, and number of slots.


The following table summarizes some of the common backplane variants for CompactPCI systems:
