Description:
The Microchip Technology Inc. 24AA128/24LC128/
24FC128 (24XX128*) is a 16K x 8 (128 Kbit) Serial
Electrically Erasable PROM (EEPROM), capable of
operation across a broad voltage range (1.7V to 5.5V).
It has been developed for advanced, low-power
applications such as personal communications or data
acquisition. This device also has a page write capabil-
ity of up to 64 bytes of data. This device is capable of
both random and sequential reads up to the 128K
boundary. Functional address lines allow up to eight
devices on the same bus, for up to 1 Mbit address
space. This device is available in the standard 8-pin
plastic DIP, SOIC (3.90 mm and 5.28 mm), TSSOP,
MSOP, DFN, and Chip Scale packages.
