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, TDFN and Chip Scale packages.
