LE25FS406

Overview

The LE25FS406 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 LE25FS406 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

LE25FS406 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.
