M27C4001 is a 4Mbit EPROM available in UV and OTP types, and is ideally suited for microprocessor systems requiring large programs.
The M27C4001 is a 4 Mbit EPROM offered in UV (ultraviolet erase) and OTP (one‑time programmable) versions. It is organised as 524,288 × 8 bits and is intended for micro‑processor systems that require large program memory.
The handbook contains absolute maximum ratings, DC and AC electrical characteristics, programming procedures, timing diagrams, and mechanical data for the various package options (FDIP32W, LCCC32W, PDIP32, PLCC32, TSOP32). It also describes standby and active power consumption, two‑line output control, and recommended decoupling practices.
