24AA00/24LC00/

24C00 (24XX00*) is a 128-bit Electrically Erasable

PROM memory organized as 16 x 8 with a 2-wire serial

interface. Low voltage design permits operation down

to 1.8 volts for the 24XX00 version, and every version

maintains a maximum standby current of only 1

µA and

typical active current of only 500

µA. This device was

designed for where a small amount of EEPROM is

needed for the storage of calibration values, ID

numbers or manufacturing information, etc. The

24XX00 is available in 8-pin PDIP, 8-pin SOIC (150

mil), 8-pin TSSOP and the 5-pin SOT-23 packages.
