Overview
The LE25CB643TT-BH (hereinafter referred to as ‘this device’) 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.
