Overview
The M27C801-80F1 is an 8 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 1,048,576 by 8 bits, making it suitable for applications requiring fast turn-around and pattern experimentation.
The M27C801 is offered in various packages, including FDIP32W (window ceramic frit-seal package), PDIP32, and PLCC32. The FDIP32W package features a transparent lid, allowing for UV erasure, while the PDIP32 and PLCC32 packages are used for OTP applications where erasure is not required.
STMicroelectronics also offers the M27C801 in ECOPACK® packages, which are lead-free and comply with environmental standards.
