The Processor and Cache Module (PCM) is a 17 x 17 pin grid array (PGA) circuit assembly which combines a PowerPC® microprocessor and SRAM components into a CPU subsystem. The PCM provides a standard mechanical, electrical, and functional interface which can be socketed on a computer system board and allow many combinations of processors and optional components to be easily interchanged. This document describes the general characteristics for a module consisting of a single PowerPC microprocessor and two SRAM devices for L2 cache. The PCM packaging and PGA signal definition also accomodates single processors without SRAM, and multiple processors.
