LE25S40AMC

Overview

The LE25S40A is a SPI bus flash memory device with a 4M bit (512K



8-bit) configuration that adds a high performance Dual output and Dual I/O

function. It uses a single 1.8V power supply. While making the most of the

features inherent to a serial flash memory device, the LE25S40A 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 LE25S40A 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.
