General Description

The M27C2001 is a high speed 2 Mbit 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 organised as 262,144 by 8 bits.

The FDIP32W (window ceramic frit-seal package) and LCCC32W (leadless chip carrier package) have a transparent lids which allow the user to expose the chip to ultraviolet light to erase the bit pattern.

Overview

M27C2001 2 Mbit (256Kb x 8) UV EPROM and OTP EPROM s 5V ± 10% SUPPLY VOLTAGE in READ OPERATION FAST ACCESS TIME: 55ns LOW POWER CONSUMPTION: – Active Current 30mA at 5MHz – Standby Current 100µA 1 1 32 32 s s s s s PROGRAMMING VOLTAGE: 12.75V ± 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. This e.
