Description:

• Preprogrammed 32-Bit Serial Number:

- Unique across all UID-family EEPROMs

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.

- Scalable to 48-bit, 64-bit, 128-bit, 256-bit,

and other lengths

• Single Supply with Operation Down to 1.7V

• Low-Power CMOS Technology:

- Read current 1 mA, max.

- Standby current 1 A, max.

• 2-Wire Serial Interface, I²C™ Compatible

• Schmitt Trigger Inputs for Noise Suppression

• Output Slope Control to Eliminate Ground Bounce

• 100 kHz and 400 kHz Clock Compatibility

• Page Write Time 3 ms, typical

• Self-Timed Erase/Write Cycle

• Page Write Buffer:
