Overview
The M27C4001-70C6 is a 4 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 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 (window ceramic frit-seal package), PDIP32, PLCC32, and TSOP32 (8 x 20 mm). The FDIP32W package features a transparent lid for UV erasure, while the other packages are designed for OTP applications. All packages are ECOPACK® compliant, which means they are lead-free and meet environmental requirements.
