DESCRIPTION
The Microchip Technology Inc. 27LV64 is a low-voltage
(3.0 volt) CMOS EPROM designed for battery powered
applications. The device is organized as 8K x 8 (8K-
Byte) non-volatile memory product. The 27LV64 con-
sumes only 8mA maximum of active current during a
3.0 volt read operation therefore improving battery per-
formance. This device is designed for very low voltage
applications where conventional 5.0 volt only EPROMs
can not be used. Accessing individual 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 system 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.
