The LE25S20XA is a SPI bus flash memory device with a 2M bit (256K x 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 LE25S20XA is housed in an 8-pin ultra-miniature package. All these features make this device ideally suited to storing program in applications more compact dimensions. The LE25S20XA 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 dueto insufficient capacity.
