SST25WF080B
8 Mbit 1.8V SPI Serial Flash
All devices are RoHS compliant
Features
Single Voltage Read and Write Operations
Product Description
- 1.65-1.95V
Serial Interface Architecture
SST25WF080B is a member of the Serial Flash 25
- SPI Compatible: Mode 0 and Mode 3 Series family and feature a four-wire, SPI-compatible
interface that allows for a low pin-count package which
High Speed Clock Frequency
occupies less board space and ultimately lowers total

system costs. SPI serial flash memory is manufactured
Dual Input/Output Support
with proprietary, high-performance CMOS SuperFlash
