256KB/512KB BurstRAM Secondary Cache Modules For PowerPC PReP/CHRP Platforms

The MPC2104P (256KB) and MPC2105P (512KB) are designed to provide burstable, high performance 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 MPC2104P and MPC2105P utilize synchronous BurstRAMs. The MPC2104P module is configured as 32K x 64 bits and uses two of the 3.3 V 32K x 32 data RAMs. The MPC2105P is configured as 64K x 64 bits and uses two of the 3.3 V 64K x 32 data RAMs. Both modules are in a 178 (89 x 2) pin DIMM format. For tag bits on the 2104P, a 5 V cache tag RAM configured as 8K x 14 for tag field plus 8K x 2 for valid and dirty status bits is used. For tag bits on the 2105P, a 5 V cache tag RAM By Freescale Semiconductor, Inc
