... Die Sales: Wafer Form, Tape and Reel, and Bumped Wafers 2. Description The AT24HC02B provides 2048 bits of serial electrically erasable and programmable read-only memory (EEPROM) organized as 256 words of 8 bits each. The device is optimized for use in many industrial and commercial applications where low-power and low-voltage operation are essential ...
