M27V256 Datasheet PDF - STMicroelectronics

DESCRIPTION
The M27V256 is a low voltage 256 Kbit EPROM offeredin the two rangesUV (ultravioleterase)and OTP (one time programmable). It is ideally suited for microprocessor systems and is organized as 32,768 by 8 bits. The M27V256 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.
