256KB and 512KB BurstRAM  
Secondary Cache Module for  
Pentium  
136–LEAD DIMM  
CASE 1104–01  
TOP VIEW  
The MCM72BA32SG and MCM72BA64SG are designed to provide a burst-  
able, high performance, 256K/512K L2 cache for the Pentium microprocessor.  
The modules are configured as 32K x 72 and 64K x 72 bits in a 136 pin dual read-  
out single inline memory module (DIMM). The module uses four of Motorola’s  
MCM67B518 or MCM67B618 BiCMOS BurstRAMs.

Bursts canbeinitiatedwitheitheraddressstatusprocessor(ADSP) or address  
status controller (ADSC). Subsequent burst addresses are generated internal to  
the BurstRAM by the burst advance (ADV) input pin.  
Write cycles are internally self timed and are initiated by the rising edge of the  
clock (K) input. Eight write enables are provided for byte write control.  
The cache family is designed to interface with popular Pentium cache control-  
lers with on board TAG.  
PD0 – PD2 are reserved for density and speed identification.

Pentium–style Burst Counter on Board  
Dual Readout SIMM for Circuit Density  
Single 5 V ± 5% Power Supply  
All Inputs and Outputs are TTL Compatible  
Three State Outputs  
Byte Parity

Fast Module Clock Rates: 66 MHz, 60 MHz, 50MHz  
Decoupling Capacitors for each Fast Static RAM  
High Quality Multi–Layer FR4 PWB With Separate Power and Ground Planes  
I/Os are 3.3 V Compatible
