256KB and 512KB BurstRAM

Secondary Cache Module for

PowerPC – Based Systems

136–LEAD DIMM

CASE 1104–01

TOP VIEW

The MPC2002SG and MPC2003SG are designed to provide a burstable, high

performance, 256K/512K L2 cache for the PowerPC 60x processors. The mod-

ules are configured as 32K x 72 and 64K x 72 bits in a 136 pin dual readout single

inline memory module (DIMM). The module uses four of Motorola’s

MCM67M518 or MCM67M618 BiCMOS BurstRAMs.

Bursts can be initiated with either transfer start processor (TSP) or transfer

start controller (TSC). Subsequent burst addresses are generated internal to the

BurstRAM by the burst address advance (BAA) 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 the PowerPC 60x bus and re-

quires external tag.

PD0 – PD2 are reserved for density and speed identification.
