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 interface. Low-voltage design permits operation
down to 1.7 volts for the 24AA00 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
(3.90 mm), 8-pin TSSOP, 8-pin 2x3 DFN and the 5-pin
SOT-23 packages.
