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 main-
tains a maximum standby current of only 1 A and typ-
ical active current of only 500 A. 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.
