MCM72JG32 image

The MCM72JG32 and MCM72JG64 are designed to provide a burstable, high performance, 256K/512K L2 cache for the Pentium microprocessor in conjunction with Intel’s Triton chip set. The modules are configured as 32K x 64 and 64K x 64 bits in a 160 pin card edge memory module. Each module uses four of Motorola’s 5 V 32K x 18 or 64K x 18 BurstRAMs and one Motorola 5 V 32K x 8 FSRAM for the tag RAM.

• Pentium–Style Burst Counter on Chip
• Pipelined Data Out
• 160 Pin Card Edge Module
• Address Pipeline Supported by ADSP Disabled with Ex
• All Cache Data and Tag I/Os are TTL Compatible
• Three State Outputs
• Byte Write Capability
• Fast Module Clock Rates: 66 MHz
• Fast SRAM Access Times:15 ns for Tag RAM 9 ns for Data RAMs
• Decoupling Capacitors for Each Fast Static RAM
• High Quality Multi–Layer FR4 PWB with Separate Power and Ground Planes
• I/Os are 3.3 V Compatible on Data RAMs
• Burndy Connector, Part Number: CELP2X80SC3Z48
• Series 20 Ω Resistors for Noise Immunity
