Overview
The M27C801-100B1 is an 8 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 1,048,576 by 8 bits, making it suitable for applications where fast turn-around and pattern experimentation are crucial. The M27C801-100B1 is offered in various packages, including FDIP32W (window ceramic frit-seal package), PDIP32, PLCC32, and TSOP32, to meet different application requirements.
