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
碌A
and typ-
ical active current of only 500
碌A.
This device was
designed for where a small amount of EEPROM is
needed for the storage of calibration values, ID num-
bers 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.
