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, VSOP or SOIC packaging is available.
Tape and reel packaging is also available for PLCC or
SOIC packages.
