Overview
The M27C160-100F1 is a 16 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 designed for microprocessor systems that require large data or program storage, organized as either 2 Mbit words of 8 bits or 1 Mbit words of 16 bits. The M27C160-100F1 is suitable for applications needing high storage capacity and fast access times.
