MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MCM64AF32/D Product Preview MCM64AF32 160–LEAD CARD EDGE CASE TBD* TOP VIEW 1 256K Asynchronous Secondary Cache Module for Pentium™ The MCM64AF32 is designed to provide 256K of asynchronous L2 cache for the Pentium microprocessor in conjunction with Intel’s Triton chip set. The module is configured as 32K x 64 bits in a 160 pin card edge connector. The module uses eight Motorola 3.3 V 32K x 8 FSRAMs for the cache memory, one Motorola 5 V 32K x 8 FSRAM for the tag RAM, and an upper order address latch. Eight write enables are provided for byte write control. PD0–PD4 identify density and functionality. This cache module is plug and pin compatible with the other members of Motorola’s Triton chip set module family, the MCM72JG32SG66 (a 256K byte pipelined BurstRAM module) and the MCM72JG64SG66 (a 512K byte pipelined BurstRAM module). Low–Cost Asynchronous Solution for Triton Chip Set All Cache Data Inputs and Outputs are LVTTL (3.3 V I/O) Compatible All Tag I/Os are TTL Compatible Byte Write Capability Fast SRAM Access Times:15 ns for Data RAMs and Tag RAM Decoupling Capacitors for each Fast Static RAM and Logic Device High Quality Multi–Layer FR4 PWB With Separate Power and Ground Planes 160 Pin Card Edge Module Burndy Connector, Part Number: CELP2X80SC3Z48 42 43 80 * PAGE FOR PRELIMINARY PRELIMINARY * SEE SEE BACK CHAPTER 9 FOR CASE CASE OUTLINE.
