Description

The Microchip Technology Inc. 24AA02/24LC02B

(24XX02*) 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 1.8V, with standby and

active currents of only 1

µA and 1 mA, respectively.

The 24XX02 also has a page write capability for up to

8 bytes of data. The 24XX02 is available in the

standard 8-pin PDIP, surface mount SOIC, TSSOP and

MSOP packages and is also available in the 5-lead

SOT-23 package.
