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 package.

100 kHz for V

<2.5V

Features:

• Single supply with operation down to 1.7V for

24AA02 devices, 2.5V for 24LC02B devices

• Low-power CMOS technology:

- Read current 1 mA, typical

- Standby current 1

μA,

typical

• 2-wire serial interface, I

C™ 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

• 8-byte page write buffer

• Hardware write-protect

• ESD protection >4,000V

• More than 1 million erase/write cycles

• Data retention >200 years

• Factory programming available

• Packages include 8-lead PDIP, SOIC, TSSOP,

DFN, MSOP and 5-lead SOT-23

• Pb-free and RoHS compliant

• Temperature ranges:

- Industrial (I): -40°C to +85°C

- Automotive (E): -40°C to +125°C
