RECALL operation) take place  
automatically on powerup.  
RECALL cycles may also be initia-  
ted by a software sequence.  
Internally, RECALL is a two step  
procedure. First, the SRAM data is  
cleared and second, the nonvola-  
tile information is transferred into  
the SRAM cells.  
The RECALL operation in no way  
alters the data in the EEPROM  
cells. The nonvolatile data can be  
recalled an unlimited number of  
times.

• QS 9000 Quality Standard  
• ESD protection > 2000 V  
(MIL STD 883C M3015.7-HBM)  
• RoHS compliance and Pb- free  
• Package:SOP28 (330 mil)
