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).
