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