M27V256 - 256 Kbit 32Kb x 8 Low Voltage UV EPROM and OTP EPROM

Datasheet Summary

Description

The M27V256 is a low voltage 256 Kbit EPROM offered in the two ranges UV (ultra violet erase) and OTP (one time programmable).

It is ideally suited for microprocessor systems and is organized as 32,768 by 8 bits.

The M27V256 operates in the read mode with a supply voltage as low as 3V.

Features

  • a 2 line control function which accommodates the use of multiple memory connection. The two line control function allows: a. the lowest possible memory power dissipation, b. complete assurance that output bus contention will not occur. For the most efficient use of these two control lines, E should be decoded and used as the primary device selecting function, while G should be made a common connection to all devices in the array and connected to the READ line from the system control bus. This e.
