DESCRIPTION

The M27V402 is a low voltage, low power 4 Mbit 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.
