The Microchip Technology Inc. 34AA02/34LC02

(34XX02*) is a 2 Kbit Electrically Erasable PROM

capable of operation across a broad voltage range

(1.7V to 5.5V). This device has two software write-

protect features for the lower half of the array, as well

as an external pin that can be used to write-protect the

entire array. This allows the system designer to protect

none, half, or all of the array, depending on the

application. 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 100 nA and 1 mA,

respectively. The 34XX02 also has a page write

capability for up to 16 bytes of data. The 34XX02 is

available in the standard 8-pin PDIP, surface mount

SOIC, TSSOP, MSOP and TDFN packages. The

34XX02 is also available in the 6-lead, SOT-23

package.

• ESD Protection > 4,000V

• Software Write Protection for Lower 128 Bytes

• Hardware Write Protection for Entire Array

• More than 1 Million Erase/Write Cycles

• Data Retention > 200 Years

• 8-Lead PDIP, SOIC, TSSOP, MSOP and TDFN

packages

• 6-Lead SOT-23 Package

• Pb-free and RoHS Compliant

• Available for Extended Temperature Ranges:

- Industrial (I): -40°C to +85°C

- Automotive (E): -40°C to +125°C
