LE25U40CMD

Overview

The LE25U40CMD 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 2.5V power supply. While making the most of the

features inherent to a serial flash memory device, the LE25U40CMD 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 LE25U40CMD 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.
