PRODUCT DESCRIPTION
SST’s 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. The SST25VF080B devices are
enhanced with improved operating frequency and even
lower power consumption than the original SST25VFxxxA
devices. SST25VF080B 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. The SST25VF080B devices significantly improve perfor-
mance and reliability, while lowering power consumption.
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 Program operation is less than alternative
flash memory technologies.
The SST25VF080B device is offered in both 8-lead SOIC
(200 mils) and 8-contact WSON (6mm x 5mm) packages.
