Overview
The M27C1001-45XF1 is a 1 Mbit EPROM (Erasable Programmable Read-Only Memory) produced by STMicroelectronics. It is 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, to cater to different application needs. The UV erase type features a transparent lid that allows the chip to be exposed to ultraviolet light for erasure, while the OTP type is programmed only once and does not require erasure.
