The AT24HC02B is a serial electrically erasable and programmable read-only memory (EEPROM) with hardware data protection, organized as 256 words of 8 bits each. This product is optimized for low-power and low-voltage operation, suitable for industrial and commercial applications. It supports voltage range from 1.8V to 5.5V, and accessed via a two-wire serial interface.
The Atmel AT24HC02B is a 2048-bit (256 x 8) serial electrically erasable programmable read-only memory (EEPROM). It is optimized for industrial and commercial applications requiring low-power and low-voltage operation, supporting voltages from 1.8V to 5.5V.
