SEMICONDUCTOR TECHNICAL DATA
256KB Asynchronous
Secondary Cache Module for
PowerPC
The MPC2001 is designed to provide asynchronous 256KB L2 cache for the
PowerPC 60x processors. The module is configured as 32K x 64 bits in a 136
pin dual readout single inline memory module (DIMM). The module uses eight
of Motorola’s MCM6206 CMOS RAMs.
Eight write enables are provided for byte write control.
The cache is designed to interface with the PowerPC 60x bus and requires external tag.
PD0 – PD2 are reserved for density and speed identification.
The cache is plug and pin compatible with Motorola’s MPC2002 and MPC2003
BurstRAM synchronous cache modules.
