Description:

The

Microchip

Technology

Inc.

24AA02UID/

24AA025UID (24AA02XUID*) is a 2 Kbit Electrically

Erasable PROM with a preprogrammed, 32-bit

unique ID. The device is organized as two blocks of

128 x 8-bit memory with a 2-wire serial interface.

Low-voltage design permits operation down to 1.7V,

with maximum standby and active currents of only

1

A and 1 mA, respectively. The 24AA02XUID also

has a page write capability for up to eight bytes of

data

(16

bytes

on

the

24AA025UID).

The

24AA02XUID is available in the standard 8-pin PDIP,

8-pin SOIC, 5-lead SOT-23, and 6-lead SOT-23

packages.
