M27C320 - 32 Mbit 4Mb x8 or 2Mb x16 OTP EPROM

General Description

The M27C320 is a 32 Mbit EPROM offered in the OTP range (one time programmable).

It is ideally suited for microprocessor systems requiring large data or program storage.

It is organised as either 4 MWords of 8 bit or 2 MWords of 16 bit.

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. This e.
