Overview
The M27C4001-10C1 is a 4 Mbit EPROM (Erasable Programmable Read-Only Memory) produced by STMicroelectronics. This device is available in two main types: UV (ultra violet erase) and OTP (one time programmable). It is organized as 524,288 by 8 bits, making it suitable for microprocessor systems that require large programs.
The M27C4001 is offered in various packages, including FDIP32W, PDIP32, PLCC32, and TSOP32 (8 x 20 mm), with ECOPACK® compliant versions available to meet environmental requirements. The device features a transparent lid in the FDIP32W package, allowing for UV erasure, while other packages are designed for one-time programming.
