Description

The LE25U40PCMC is a SPI bus flash memory device with a 4M bit (512K x 8-bit) configuration that adds a high performance Dual output and Dual I/O function. It uses a single 2.5 V power supply. While making the most of the features inherent to a serial flash memory device, the LE25U40PCMC is housed in an 8-pin ultra-miniature package. All these features make this deviceideally suited to storing program in applications such as portable information devices, which are required to have increasingly more compact dimensions. The LE25U40PCMC 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.
