Product Description

The 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 SST25PF020B

devices are enhanced with improved operating frequency

and even lower power consumption.

SST25PF020B 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 SST25PF020B devices significantly improve performance

and reliability, while lowering power consumption.

The devices write (Program or Erase) with a

single power supply of 2.3V-3.6V for SST25PF020B.

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.
