Overview
The M27C1001-12B1, produced by STMicroelectronics, is a 1 Mbit EPROM available in two main ranges: 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. It offers various package options, including FDIP32W, PDIP32, PLCC32, and TSOP32, to cater to different application needs. The UV eraseable version allows for the chip to be exposed to ultraviolet light to erase the bit pattern, while the OTP version is programmed only once and does not require erasure.
