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
