MCM72F6

MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MCM72F6/D 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 registers. 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 MCM72F6 MCM72F7 168–LEAD DIMM CASE 1115J–01 TOP VIEW 1 11 40 41 84 REV 3 11/24/97 © Motorola, Inc. 1997 MOTOROLA FAST SRAM MCM72F6MCM72F7 1 MCM72F6 BLOCK DIAGRAM 64K x 18 SE1 G A0 – A15 ADSC SBa SBb K SE2 ADV ADSP SGW SW LBO SE3 DQa0 – DQa7 DQa8 DQb0 – DQb7 DQb8 64K x 18 SE1 G A0 – A15 ...
