1.2.2.10 I²C Bus Serial EEPROM
DESCRIPTION
The Microchip Technology Inc. 24AA00/24LC00/24C00 (24xx00*) is a 128-bit Electrically Erasable PROM
memory organized as 16 x 8 with a 2-wire serial inter-face. 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 mA and typical active
current of only 500 mA. This device was designed 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 8ld PDIP, 8ld SOIC (150
mil), 8ld TSSOP and the 5ld SOT-23 packages.
