DESCRIPTION
The M27V402 is a low voltage, low power 4 Megabit UV erasable and electrically programmable EPROM, ideally suited for handheld and portable microprocessor systems requiring large programs. It is organized as 262,144 by 16 bits.
The M27V402 operates in the read mode with a supply voltage as low as 3V. The decrease in operating power allows either a reduction of the size of the battery or an increase in the time between battery recharges.
The M27V402 can also be operated as a standard 4 Megabit EPROM (similar to M27C4002) with a 5V power supply.

■ LOW VOLTAGE READ OPERATION: 3V to 5.5V
■ FAST ACCESS TIME: 120ns
■ LOW POWER "CMOS" CONSUMPTION:
    – Active Current 15mA
    – Standby Current 20µA
■ PROGRAMMING VOLTAGE: 12.75V
■ PROGRAMMING TIMES of AROUND 24sec. (PRESTO II ALGORITHM)
■ M27V402 is PROGRAMMABLE as M27C4002 with IDENTICAL SIGNATURE
