Overview
The M27C2001-12C1 is a high-speed 2 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 EPROM is organized as 262,144 by 8 bits, making it suitable for microprocessor systems that require large programs.
The device 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 other packages are designed for applications where content is programmed only once and erasure is not required.
STMicroelectronics also offers the M27C2001 in ECOPACK® packages, which are lead-free and comply with environmental standards.
