The MCM6323A is a 64K x 16-bit static random access memory produced by Motorola. It is powered by 3.3V and has a working frequency of 10, 12, 15ns. All inputs and outputs are TTL compatible and it supports byte control and fully static operation. The maximum working current is 140/135/130 mA.
The MCM6323A is a 64K x 16‑bit static random‑access memory (SRAM) that operates asynchronously at 3.3 V. It features chip‑enable, write‑enable, output‑enable, and separate byte‑enable pins for flexible bus control and eliminates bus contention.
The document lists electrical characteristics such as supply voltage, access times, power consumption, and temperature ranges, as well as detailed pin assignments, timing diagrams for read and write cycles, and mechanical dimensions for the 400 mil SOJ (YJ) and 44‑lead TSOP Type II packages.
