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 1.8V, 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 and MSOP packages and is

also available in the 5-lead SOT-23 package.
