General Description

The M27C64A is a 64Kbit EPROM offered in the two ranges UV (ultra violet erase) and OTP (one time programmable).

It is ideally suited for microprocessor systems requiring large programs and is organized as 8,192 by 8 bits.

The FDIP28W (window ceramic frit-seal package) has transparent lid which allows the user to expose the chip to ultraviolet light to erase the bit pattern.

Overview

M27C64A 64 Kbit (8Kb x 8) UV EPROM and OTP EPROM 5V ± 10% SUPPLY VOLTAGE in READ OPERATION FAST ACCESS TIME: 150ns LOW POWER “CMOS” CONSUMPTION: – Active Current 30mA – Standby Current 100µA PROGRAMMING VOLTAGE: 12.5V ± 0.

Key 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.
