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 lower
power consumption. SST25VF080B SPI serial flash mem-
ories are manufactured with SST’s proprietary, high-perfor-
mance CMOS SuperFlash technology. The split-gate cell
design and thick-oxide tunneling injector attain better reli-
ability 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 8-lead SOIC (200
mils), 8-contact WSON (6mm x 5mm), and 8-lead PDIP
(300 mils) packages. See Figure 2 for pin assignments.
