MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MCM6946/D Advance Information 512K x 8 Bit Static Random Access Memory The MCM6946 is a 4,194,304- bit static random access memory organized as 524,288 words of 8 bits. Static design eliminates the need for external clocks or timing strobes. The MCM6946 is equipped with chip enable (E) and output enable (G) pins, allowing for greater system flexibility and eliminating bus contention problems. Either input, when high, will force the outputs into high- impedance. The MCM6946 is available in a 400 mil, 36- lead surface- mount SOJ package. - - - - - - - Single 3.3 V - 5%, + 10% Power Supply Fast Access Time: 8/10/12/15 ns Equal Address and Chip Enable Access Time All Inputs and Outputs are TTL patible Three- State Outputs Power Operation: 195/185 / 180 / 175 m A Maximum, Active AC Available in TSOP or SOJ Packages YJ PACKAGE 400 MIL SOJ CASE 893- 02 TS PACKAGE 44- LEAD TSOP TYPE II CASE 924A- 02 PIN NAMES A0 - A18 - - - Address Inputs W - - - - . . .
