Temp  
(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 1.8V, 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 and  
MSOP packages and is also available in the 5-lead  
SOT-23 package.
