MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MCM6343/D Product Preview MCM6343 256K x 16 Bit 3.3 V Asynchronous Fast Static RAM The MCM6343 is a 4,194,304–bit static random access memory organized as 262,144 words of 16 bits. Static design eliminates the need for external clocks or timing strobes. The MCM6343 is equipped with chip enable (E), write enable (W), and output enable (G) pins, allowing for greater system flexibility and eliminating bus contention problems. Separate byte enable controls (LB and UB) allow individual bytes to be written and read. LB controls the lower bits DQ0 to DQ7, while UB controls the upper bits DQ8 to DQ15. The MCM6343 is available in a 400 mil, 44–lead small–outline SOJ package and a 44–lead TSOP Type II package.
