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鈥檚 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 SST25VF032B 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 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 both 8-lead SOIC
(200 mils) and 16-lead SOIC (300 mils) packages. See Fig-
ures 2 and 3 for pin assignments.
