Product Description
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 ulti-
mately lowers total system costs. The SST25VF080B
devices are enhanced with improved operating fre-
quency and lower power consumption. SST25VF080B
SPI serial flash memories are manufactured with pro-
prietary, high-performance CMOS SuperFlash technol-
ogy. The split-gate cell design and thick-oxide tunneling
injector attain better reliability and manufacturability
compared with alternate approaches.
The SST25VF080B devices significantly improve per-
formance and reliability, while lowering power con-
sumption. The devices write (Program or Erase) with a
single power supply of 2.7-3.6V for SST25VF080B.
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 Pro-
gram operation is less than alternative flash memory
technologies.
The SST25VF080B device is offered in 8-lead SOIC
(200 mils), 8-contact WSON (6mm x 5mm), and 8-lead
PDIP (300 mils) packages. See Figure 2-1 for pin
assignments.
