Overview
The M27C1001-45XC1, produced by STMicroelectronics, is a 1 Mbit EPROM available in two main types: UV (ultra violet erase) and OTP (one time programmable). This device is ideally suited for microprocessor systems that require large programs and is organized as 131,072 words of 8 bits. The M27C1001 is offered in various packages, including FDIP32W, PDIP32, PLCC32, and TSOP32, catering to different application needs. The UV EPROM version allows for erasure using ultraviolet light, while the OTP version is programmed only once and does not require erasure.
