LE25S20FD

Serial Flash Memory

2 Mb (256K x 8)

Overview

The LE25S20FD is a SPI bus flash memory device with a 2M bit (256K

 8-

bit) configuration. It uses a single 1.8 V power supply. While making the

most of the features inherent to a serial flash memory device, the

LE25S20FD 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 LE25S20FD 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.
