2764A - 64K (8K x 8) UV EPROM and OTP ROM

Description

The M27C64A is a high speed 65,536 bit UV erasable and electrically programmable memory EPROM ideally suited for microprocessor systems requiring large programs.

It is organized as 8,192 by 8 bits.

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.
