MOTOROLA Order this document by MCM72F10/D SEMICONDUCTOR TECHNICAL DATA 8MB Synchronous Fast Static RAM Module The MCM72F10 (2MB) is configured as 1M x 72 bits. It is packaged in a 168–pin dual–in–line memory module DIMM. The module uses Motorola’s 3.3 V, 256K 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.

X = don’t care, 1 = logic high, 0 = logic low. 2. Write is defined as any Wx low. 3. G is an asynchronous signal and is not sampled by the clock K. G drives the bus immediately (tGLQX) following G going low. 4. On write cycles that follow read cycles, G must be negated prior to the start of the write cycle to ensure proper write data setup times. G must also remain negated at the completion of the write cycle to ensure proper write data hold times.

NOTES: 1. Permanent device damage may occur if ABSOLUTE MAXIMUM RATINGS are exceeded. Functional operation should be restricted to RECOMMENDED OPERATING CONDITIONS. Exposure to higher than recommended voltages for extended periods of time could affect device reliability. 2. This is a steady–state DC parameter that is in effect after the power supply has achieved its nominal operating level. Power sequencing can not be controlled and is not allowed. 3. Power dissipation capability is dependent upon package characteristics and use environment. See Package Thermal Characteristics.
