描述 Description

The LE25CB643TT-BH is serial peripheral interface EEPROM (Electrically Erasable and Programmable ROM). This device realizes high speed and a high level reliability by incorporating high performance CMOS EEPROM technology. This device is compatible with SPI memory protocol, therefore it is best suited for application that requires re-writable nonvolatile parameter memory. And this device has 32bytes page write function for high speed data re-write.
