mx27c256pc-70 Description

Short technical summary and product information.

The MX27C256PC-70 is a 256Kbit UV-erasable programmable read-only memory (EPROM) from Macronix, organized as 32K words by 8 bits. It provides a fast 70ns access time, making it suitable for high-speed memory applications in microprocessor systems. The device operates from a single 5V power supply and utilizes CMOS technology for low power consumption.

This EPROM is ideal for firmware storage, code development, and prototyping, offering reliable non-volatile memory retention. The part comes in a plastic DIP package, providing easy handling and socketing for development boards. Compatible with industry-standard 27C256 EPROMs, it can be used as a drop-in replacement in existing designs.

Typical applications include embedded systems, industrial controllers, and legacy computer systems requiring reprogrammable non-volatile memory. The MX27C256PC-70 is RoHS3 compliant and has an MSL rating of 1 (unlimited), though these compliance claims are not independently verified.
