256K/512K Pipelined BurstRAMTM Secondary Cache Module for PentiumTM

The MCM64PE32 (256K) and MCM64PE64 (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 MCM64PE32 is configured x 64 bits and the MCM64PE64 is configured x 64 bits. Both are packaged a 160 pin card edge memory module. The MCM64PE32 module uses Motorola's x 32 BurstRAMs and one Motorola x 8 FSRAM for the tag RAM. The MCM64PE64 module uses Motorola's x 32 BurstRAMs and one Motorola x 8 FSRAM for the tag RAM. Bursts can be initiated with either address status processor (ADSP) or cache address status (CADS). Subsequent burst addresses are generated internal to the BurstRAM by the cache burst advance (CADV) input pin. Write cycles are internally self timed and are initiated by the rising edge of the clock (CLK0) input. Eight write enables are provided for byte write control. ­ PD3 map into the Triton II chip set for auto­configuration of the cache control.
