Description:

The Microchip Technology Inc. 24AA04/24LC04B

(24XX04*) is a 4 Kbit Electrically Erasable PROM. The

device is organized as two blocks of 256 x 8-bit

memory with a 2-wire serial interface. Low-voltage

design permits operation down to 1.7V, with standby

and

active

currents

of

only

1

μA and 1 mA,

respectively. The 24XX04 also has a page write

capability for up to 16 bytes of data. The 24XX04 is

available in the standard 8-pin PDIP, surface mount

SOIC, TSSOP, 2x3 DFN, 2x3 TDFN, and MSOP

packages and is also available in the 5-lead SOT-23, or

4-lead Chip Scale package.
