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 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.
