Overview
The LE25S40QE is a SPI bus flash memory device with a 4M bit (512K 8-
bit) configuration. It uses a single 1.8V power supply. While making the
most of the features inherent to a serial flash memory device, the
LE25S40QE 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 LE25S40QE 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.
