Two-Wire Serial EEPROM

General Description

The

24C02 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 essentia l. The

24C02 is available in space-saving 8-lead SOP, 8-lead TSSOP and SOT23-5

packages and is accessed via a two-wire serial interface.
