PRODUCT DESCRIPTION
The SST25WF080 is a member of the Serial Flash 25
Series family and features a four-wire, SPI-compatible
interface that allows for a low pin-count package which
occupies less board space and ultimately lowers total sys-
tem costs. SST25WF080 SPI serial flash memory is manu-
factured 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 consumption. 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 Super-
Flash 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 package. See Fig-
ures 2 and 3 for the pin assignments.
