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 and DFN packages.

100 kHz for V

< 2.5V.

400 kHz for V

< 2.5V.

Features:

• Single supply with operation down to 1.7V for

24AA128/24FC128 devices, 2.5V for 24LC128

devices

• Low-power CMOS technology:

- Write current 3 mA, typical

- Standby current 100 nA, typical

• 2-wire serial interface, I

C™ compatible

• Cascadable up to eight devices

• Schmitt Trigger inputs for noise suppression

• Output slope control to eliminate ground bounce

• 100 kHz and 400 kHz clock compatibility

• 1 MHz clock for FC versions

• Page write time 5 ms, typical

• Self-timed erase/write cycle

• 64-byte page write buffer <adjust per device>

• Hardware write-protect

• ESD protection >4000V

• More than 1 million erase/write cycles

• Data retention > 200 years

• Factory programming available

• Packages include 8-lead PDIP, SOIC, TSSOP,

DFN and MSOP packages

• Pb-free and RoHS compliant
