The MCM72F8 (2MB) is configured as 256K x 72 bits and the MCM72F9 (4MB) is configured as 512K x 72 bits. Both are packaged in a 168âpin dualâinâline memory module DIMM. Each module uses Motorolaâs 3.3 V 256K 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 registers.
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.
