LE25U81AQE

CMOS LSI

8M-bit (1024K x 8) Serial Flash Memory

http://onsemi.com

Overview

The LE25U81AQE is a SPI bus flash memory device with a 8M bit (1024K ï´ 8-bit) configuration that adds a high

performance Dual output and Dual I/O function. It uses a single 2.5V power supply. While making the most of the

features inherent to a serial flash memory device, the LE25U81AQE is housed in an 8-pin ultra-miniature package. All

these features make this device ideally suited to storing program in applications such as portable information devices,

which are required to have increasingly more compact dimensions. The LE25U81AQE also has a small sector erase

capability which makes the device ideal for storing parameters or data that have fewer rewrite cycles and conventional

EEPROMs cannot handle due to insufficient capacity.
