Description

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 memories are manufactured with 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 performance

and reliability, while lowering power consumption.

The devices write (program or erase) with a

single power supply of 2.7V-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.
