MOTOROLA

SEMICONDUCTOR TECHNICAL DATA

512KB and 1MB Synchronous

Fast Static RAM Module

The MCM72F6 (512KB) is configured as 64K x 72 bits and the MCM72F7

(1MB) is configured as 128K x 72 bits. Both are packaged in a 168–pin dual–

in–line memory module DIMM. Each module uses Motorola’s 3.3 V 64K x 18 bit

flow–through BurstRAMs.

Address (A), data inputs (DQ, DP), and all control signals except output enable

(G) are clock (K) controlled through positive–edge–triggered noninverting reg-

isters.

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

clock (K) input. This feature provides increased timing flexibility for incoming

signals. Synchronous byte write (W) allows writes to either individual bytes or to

both bytes.

• Single 3.3 V + 10%, – 5% Power Supply

• Plug and Pin Compatibility with 2MB and 4MB

• Multiple Clock Pins for Reduced Loading

• All Inputs and Outputs are LVTTL Compatible

• Byte Write Capability

• Fast SRAM Access Times: 9/10/12 ns

• Decoupling Capacitors for Each Fast Static RAM

• High Quality Multi–Layer FR4 PWB With Separate Power and Ground

Planes

• Amp Connector, Part Number: 390064–4

• 168–Pin DIMM Module
