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
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.
I2C is a trademark of Philips Corporation.
*24XX00 is used in this document as a generic part number for
the 24AA00/24LC00/24C00 devices.
