Overview
The LE25U40CMC-AH-2 is a SPI bus flash memory device produced by ON Semiconductor. It features a 4M bit (512K x 8-bit) configuration, enhancing its performance with Dual output and Dual I/O functions. This device is designed to operate with a single 2.5V power supply within a voltage range of 2.3 to 3.6V. The ultra-miniature 8-pin package makes it ideal for compact portable information devices. The LE25U40CMC-AH-2 also includes small sector erase capabilities, making it suitable for storing parameters or data that require fewer rewrite cycles than conventional EEPROMs can handle.
