MOTOROLA Order this document by MCM64PC32/D SEMICONDUCTOR TECHNICAL DATA Advance Information 256K/512K Pipelined BurstRAM Secondary Cache Module for Pentium MCM64PC32 MCM64PC64 160–LEAD CARD EDGE CASE TBD, TOP VIEW 1 The MCM64PC32 (256K) and MCM64PC64 (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 MCM64PC32 is configured as 32K x 64 bits and the MCM64PC64 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 one 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). 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. PD0 – PD3 map into the Triton II chip set for auto–configuration of the cache control. • • • • • • • • • • • • • • • • 42 43 Pentium–Style Burst Counter on Chip Pipelined Data Out 160 Pin Card Edge Module Address Pipeline Supported by ADSP Disabled with Ex All Cache Data and Tag I/Os are TTL Compatible Three State Outputs Byte Write Capability Fast Module Clock Rate: 66 MHz Fast SRAM Access Times:15 ns for Tag RAM 8 ns for Data RAMs One–Cycle Deselect Data RAMs Decoupling Capacitors for Each Fast Static RAM High Quality Multi–Layer FR4 PWB with Separate Power and Ground Planes Single 3.3 V +10%, – 5% Power Supply Burndy Connector, Part Number: CELP2X80SC3Z48 Intel COAST 3.0 Option III Compliant Burst Order Select (BOSEL) Option 80 BurstRAM is a trademark of Motorola.

Input requirements are specified from the external system point of view. Thus, address setup time is shown as a minimum since the system must supply at least that much time (even though most devices do not require it). On the other hand, responses from the memory are specified from the device point of view. Thus, the access time is shown as a maximum since the device never provides data later than that time.
