Description:

The Microchip Technology Inc. 24AA02H/24LC02BH

(24XX02H*) is a 2 Kbit Electrically Erasable PROM.

The device is organized as one block 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, respec-

tively. The 24XX02H also has a page write capability for

up to 8 bytes of data. The 24XX02H 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 and SC-70 packages.
