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, 2x3 TDFN and MSOP packages and is also avail-

able in the 5-lead SOT-23 and SC-70 packages.

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, max.

- Standby current 1

μA,

max. (I-temp)

• 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, TDFN, MSOP, 5-lead SOT-23 and SC-70

• Pb-free and RoHS Compliant

• Temperature Ranges:

- Industrial (I): -40°C to +85°C

- Automotive (E): -40°C to +125°C
