MOTOROLA
SEMICONDUCTOR TECHNICAL DATA
512KB and 1MB Synchronous
Fast Static RAM Module
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 168âpin dualâ
inâline memory module DIMM. Each module uses Motorolaâs 3.3 V 64K x 18 bit
flowâthrough BurstRAMs.
Address (A), data inputs (DQ, DP), and all control signals except output enable
(G) are clock (K) controlled through positiveâedgeâtriggered noninverting reg-
isters.
Write cycles are internally selfâtimed 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%, â 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 MultiâLayer FR4 PWB With Separate Power and Ground
Planes
⢠Amp Connector, Part Number: 390064â4
⢠5 V Tolerant on All Pins (Inputs and I/Os)
⢠168âPin DIMM Module
