Serial EEPROM

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 1.7V, 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, 2x3

DFN and MSOP packages and is also available in the

5-lead SOT-23 and SC-70 packages.
