Mitsubishi LSIs M5M51008CP, FP, VP, RV, KV, KR -55H, -70H, -55X, -70X 1048576-BIT(131072-WORD BY 8-BIT) CMOS STATIC RAM is a low power CMOS static RAM manufactured by Mitsubishi Electric. It has a capacity of 1048576 bits, 131072 words x 8 bits, and is fabricated using high-performance quadruple-polysilicon and double metal CMOS technology. The use of thin film transistor (TFT) load cells and CMOS periphery results in a high density and low power static RAM. The chip has low standby current and low operation current, making it ideal for battery backup applications. It is packaged in a 32-pin thin small outline package, which is a high reliability and high density surface mount device (SMD).
The Mitsubishi M5M51008 series are 1 M‑bit (131 072‑word × 8‑bit) CMOS static RAM devices offered in several package types (DIP, SOP, TSOP). They feature low standby current, high‑density layout and TTL‑compatible I/O, making them suitable for battery‑back‑up applications.
The document provides full pin configurations, functional block diagrams, absolute maximum ratings, DC electrical characteristics, read/write timing diagrams and power‑down behavior for the -55H, -70H, -55X and -70X variants.
