Product Introduction

Overview

The M27C4001-70C1 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 ideally suited for microprocessor systems that require large programs and is organized as 524,288 by 8 bits. The M27C4001 is offered in various packages, including FDIP32W, PDIP32, PLCC32, and TSOP32, with ECOPACK® compliant versions available to meet environmental requirements.
