PRODUCT DESCRIPTION  
The SST25WF080 is a member of the Serial Flash 25  
Series family and features a four-wire, SPI-compatible  
interface that allows for a low pin-count package which  
occupies less board space and ultimately lowers total sys-  
tem costs. SST25WF080 SPI serial flash memory is manu-  
factured with SST proprietary, high-performance CMOS  
SuperFlash technology. The split-gate cell design and  
thick-oxide tunneling injector attain better reliability and  
manufacturability compared with alternate approaches.  
1.65-1.95V for SST25WF080. The total energy consumed  
is a function of the applied voltage, current, and time of  
application. Since for any given voltage range, the Super-  
Flash technology uses less current to program and has a  
shorter erase time, the total energy consumed during any  
Erase or Program operation is less than alternative flash  
memory technologies.  
The SST25WF080 is offered in both an 8-lead, 150 mils  
SOIC package and an 8-bump XFBGA package. See Fig-  
ures 2 and 3 for the pin assignments.  
The SST25WF080 significantly improves performance and  
reliability, while lowering power consumption. The device  
writes (Program or Erase) with a single power supply of
