Overview
The M27C1001-10B1 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 each.
The M27C1001 is offered in various packages, including FDIP32W (window ceramic frit-seal package), PDIP32, PLCC32, and TSOP32 (8 x 20 mm). The UV EPROM version features a transparent lid that allows the chip to be erased using ultraviolet light, while the OTP version is programmed only once and does not require erasure.
STMicroelectronics also offers the M27C1001 in ECOPACK® packages, which are lead-free and comply with environmental standards.
