The Mitsubishi M5M5256CP series is a 262,144‑bit (32,768‑word × 8‑bit) CMOS static RAM offered in several package types (55LL, 55XL, 70LL, 70XL). It features low standby current, TTL‑compatible I/O, and three‑state outputs suitable for memory expansion and battery‑backed operation.
The datasheet provides absolute maximum ratings, DC and AC electrical characteristics, timing diagrams for read and write cycles, and power‑down behavior. Detailed parameter tables list typical values such as 55 ns access time, 5 V ±10 % supply voltage, and 0.2 µA standby current.
| Supply voltage (VCC) | 5 V ±10 % |
|---|---|
| Input high‑level voltage | 2.2 V |
The chip operates from a 5 V supply with a ±10 % tolerance.
Yes, all inputs and outputs are TTL compatible.
