MOTOROLA • SEMICONDUCTOR TECHNICAL DATA Advance Information 128KB/256KB/512KB Secondary Cache Module With Tag, Valid, and Dirty for 486 Processor Based Systems MCM32AB32 MCM32AB64 MCM32AB128 The MCM32AB32SG, MCM32AB64SG, and MCM32AB128 are a family of Motorola's asynchronous secondary cache modules for the 486 processor. This family is suited for the Intel 82420 PCI chipset. The modules are configured with 32 bit data, 7 bit tag, valid and a dirty bit for cache writeback. The family supports three cache sizes of the 486 processor. The MCM32AB32SG is a 128KB single bank cache of 32K x 32. The tag/valid is 8K x 8, and the Dirty bit is 8K x 1. The MCM32AB64SG is a 256KB double bank cache of 64K x 32. The tag/valid is 16K x 8 and the Dirty bit is 16K x 1.
