DATA BRIEFING

PLCC44 (C)

DESCRIPTION

The M27V402 is a low voltage, low power 4 Mega-

bit 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 be-

tween battery recharges.

The M27V402 can also be operated as a standard

4 Megabit EPROM (similar to M27C4002) with a

5V power supply.
