M27V101 1 Mbit EPROM Technical Summary

Overview

The M27V101 is a low-voltage 1 Mbit (128K x 8) EPROM available in two variants: UV-erasable (ultraviolet erase) and OTP (One Time Programmable). This component is designed for applications requiring non-volatile memory with reliable data retention and easy reprogrammability (in the case of the UV-erasable version). The M27V101 operates at a low voltage, making it suitable for power-sensitive applications while maintaining high performance and compatibility with standard EPROM interfaces.

With its robust architecture and industry-standard pinout, the M27V101 is ideal for embedded systems, legacy equipment upgrades, and applications where firmware updates are required during development cycles (UV version) or where permanent programming is needed (OTP version).
