Product Summary
The AT24HC02B-TH-B is a 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. The AT24HC02B-TH-B is available in space-saving 8-lead PDIP, 8-lead JEDEC SOIC and 8-lead TSSOP packages and is accessed via a two-wire serial interface. In addition, the entire family is available in 1.8V (1.8V to 5.5V) version.
