Description:

The Microchip Technology Inc. 24AA04H/24LC04BH

(24XX04H*) is an 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 24XX04H also has a page write

capability for up to 16 bytes of data. The 24XX04H is

available in the standard 8-pin PDIP, surface mount

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

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

packages are Pb-free and RoHS compliant.
