Advance Information
256KB and 512KB BurstRAMTM Secondary Cache Module for PentiumTM
The MCM72CF32SG and MCM72CF64SG are designed to provide a burstable, 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 160 pin card edge memory module. The module uses four of Motorola's MCM67C518 or MCM67C618 BiCMOS BurstRAMs. Bursts can be initiated with either address status processor (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 controllers with on board tag. PD0 PD2 are reserved for density identification. · Pentiumstyle Burst Counter on Board · Pipelined Data Out · 160 Pin Card Edge Module · Single 5 V ± 5% Power Supply · All Inputs and Outputs are TTL Compatible · Three State Outputs · Byte Parity · Byte Write Capability · Fast Module Clock Rates: 66 MHz · Decoupling Capacitors for each Fast Static RAM · High Quality MultiLayer FR4 PWB With Separate Power and Ground Planes · I/Os are 3.3 V Compatible · Burndy Connector, Part Number: CELP2X80SC3Z48 · Series 20 Resistors for Noise Immunity
