Description

The MCM72F6A (512KB) is configured as 64K x 72 bits and the MCM72F7A (1MB) is configured as 128K x 72 bits. Both are packaged in a 168pin dualinline memory module DIMM. Each module uses Motorola's 3.3 V 64K x 18 bitflowthrough BurstRAMs.

Address (A), data inputs (DQ, DP) of the MCM72F7A, and all control signals except output enable(G) are clock (K) controlled through positiveedgetriggered noninverting reg-isters.

Write cycles of the MCM72F7A are internally selftimed 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.
