Two-wire Automotive Temperature Serial EEPROM

Description
The AT24C02A/04A provides 2048/4096 bits of serial electrically erasable and programmable read-only memory (EEPROM) organized as 256/512 words of 8 bits each. The device is optimized for use in many automotive applications where low-power and low-voltage operation are essential.
