256K/512K Pipelined BurstRAM™ Secondary Cache Module for Pentium™
The MCM64PD32 (256K) and MCM64PD64 (512K) are designed to provide a burstable, high performance, L2 cache for the Pentium microprocessor in conjunction with Intel’s Triton II chip set. The MCM64PD32 is configured as 32K x 64 bits and the MCM64PD64 is configured as 64K x 64 bits. Both are packaged in a 160 pin card edge memory module. Each module uses Motorola’s 3.3 V 32K x 32 BurstRAMs and two Motorola 3.3 V 32K x 8 FSRAM for the tag RAM. Bursts can be initiated with either address status processor (ADSP) or cache address status (CADS).
