Advance Information

256KB and 512KB BurstRAM

Secondary Cache Modules for

PowerPC PReP/CHRP Platforms

The MPC2004 and MPC2005 are designed to provide burstable, high perfor-

mance 256KB/512KB L2 cache for the PowerPC 60x microprocessor family in

conformance with the PowerPC Reference Platform (PReP) and the PowerPC

Common Hardware Reference Platform (CHRP) specifications. The modules

are configured as 32K x 72 and 64K x 72 bits in a 182 (91 x 2) pin DIMM format.

Each module uses four of Motorola’s 5 V 32K x 18 or 64K x 18 BurstRAMs and

a 5 V cache tag RAM configured as 16K x 12 for tag field plus 16K x 2 for valid and

dirty status bits.

Bursts can be initiated with the SRAMADS signal. Subsequent burst address-

es are generated internal to the BurstRAM by the SRAMCNTEN signal.

Write cycles are internally self timed and are initiated by the rising edge of the

clock (CLKx) inputs. Eight write enables are provided for byte write control.

Presence detect pins are available for auto configuration of the cache control.

A serial EEPROM is optional to provide more in–depth description of the

cache module.

to lower voltage and power savings. Both power supplies must be connected.

These cache modules are plug and pin compatible with the MPC2006, a 1MB

synchronous module also designed for the PReP and CHRP specifications.

They are also compatible with the MPC2007 and MPC2009, 256KB and 1MB re-

spectively, asynchronous cache modules.
