M27C1001 is a 1 Mbit EPROM offered in the two ranges UV (ultra violet erase) and OTP (one time programmable). It is ideally suited for micro- processor systems requiring large programs and is organized as 131,072 words of 8 bits.
This handbook describes the M27C1001 1 Mbit (128 Kb × 8) UV EPROM and OTP EPROM. It lists electrical characteristics, timing diagrams, programming algorithms, and the electronic signature used for device identification. The document also covers package options (FDIP32W, PDIP32, PLCC32, TSOP32, LCCC32W) and mechanical dimensions.
Operational information includes read mode timing, standby mode current reduction, programming voltage and pulse requirements, as well as erasure procedures for the UV version. Ordering information, temperature ranges, and safety notices are provided at the end of the document.
