Description

The AT24C11 provides 1024 bits of serial electrically erasable and programmable

read only memory (EEPROM) organized as 128 words of 8 bits each. The device is

optimized for use in many automotive applications where low power and low voltage

operation are essential. The AT24C11 is available in space saving 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 2.7V (2.7V to 5.5V).
