PRODUCT DESCRIPTION  
The SST 25 series Serial Flash family features a four-wire,  
SPI-compatible interface that allows for a low pin-count  
package which occupies less board space and ultimately  
lowers total system costs. SST25VF032B SPI serial flash  
memories are manufactured with SST’s 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.  
supply of 2.7-3.6V for SST25VF032B. The total energy  
consumed is a function of the applied voltage, current, and  
time of application. Since for any given voltage range, the  
SuperFlash 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 SST25VF032B device is offered in 8-lead SOIC (200  
mils) and 8-contact WSON packages. See Figure 2 for pin  
assignments.  
The SST25VF032B devices significantly improve perfor-  
mance and reliability, while lowering power consumption.  
The devices write (Program or Erase) with a single power
