SST25WF080
Not Recommended for New Designs
Product Description
The SST25WF080 is a member of the Serial Flash 25 Series family and features a four-wire, SPI-com-
patible interface that allows for a low pin-count package which occupies less board space and ulti-
mately lowers total system costs. SST25WF080 SPI serial flash memory is manufactured 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.
The SST25WF080 significantly improves performance and reliability, while lowering power consump-
tion. The device writes (Program or Erase) with a single power supply of 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 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 SST25WF080 is offered in both an 8-lead, 150 mils SOIC package and an 8-bump XFBGA pack-
age. See Figures 2 and 3 for the pin assignments.
