DATA BRIEFING

LCCC32W (L)

DESCRIPTION

The M27V401 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 524,288 by 8 bits.

The M27V401 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 M27V401 can also be operated as a standard

4 Megabit EPROM (similar to M27C4001) with a

5V power supply.
