DESCRIPTION

The Microchip Technology Inc. 27LV256 is a low volt-

age (3.0 volt) CMOS EPROM designed for battery

powered applications. The device is organized as a

32K x 8 (32K-Byte) non-volatile memory product. The

27LV256 consumes only 8 mA maximum of active cur-

rent during a 3.0 volt read operation therefore improv-

ing battery performance. This device is designed for

very low voltage applications where conventional 5.0

volt only EPROMS can not be used. Accessing individ-

ual bytes from an address transition or from power-up

(chip enable pin going low) is accomplished in less than

200 ns at 3.0V. This device allows systems designers

the ability to use low voltage non-volatile memory with

today’s' low voltage microprocessors and peripherals in

battery powered applications.

A complete family of packages is offered to provide the

most flexibility in applications. For surface mount appli-

cations, PLCC or SOIC packaging is available. Tape

and reel packaging is also available for PLCC or SOIC

packages.
