Saifun’s SA25F family of SPI

devices provides small-sized,

cost-effective, low-power and

high-performance Serial Flash

memory chips for today’s market

needs. Using the patented Saifun

NROM™ technology, the SA25F

devices contain two bits per cell,

which ensures minimal die size

and maximal growth within the

same package with increasing

densities.

Fastest Access Times

The SA25F family sets the industry speed

record for serial non-volatile memories:

• The 512Kb to 2Mb devices run at 25

MHz (as compared to the industry

standard of 20 MHz)

• The 4Mb to 32Mb devices run at over

40 MHz (as compared to the industry's

current best speed of 33 MHz)

Minimal System Cost

System cost is affected by both footprint

and package cost. Saifun's 512Kb to 16Mb

SPI Serial Flash devices have the same

small footprint as the industry standard's

8-pin narrow SOIC packages (the 512Kb to

4Mb devices are available in 8-pin narrow

SOIC packages; the 512Kb to 16Mb devices

in leadless MLF packages).

The devices' small footprint saves board

space and reduces system overhead cost.

This enables to be added new features and

capabilities to your products simply and

easily, without costly, time-consuming

redesigns.

Easy Migration

The Saifun 512Kb to 2Mb SPI Serial Flash

devices have the industry's smallest Erase

Block (a 256-byte Page Erase, as compared

to the standard 256Kb Sector Erase). This

unique Page Erase feature, taken together

with Saifun NROM technology and the

devices' small footprint, gives a clear

migration path from low-density SPI EEPROMs

(2Kb to 256Kb) to the higher-density (512Kb

to 16Mb) SA25F family.

Reduced Power Consumption

Saifun NROM technology uses far less power

in system standby mode than any other SPI

device on the market, which makes the

SA25F family ideal for portable applications.

Greater Reliability

Saifun NROM technology has high immunity

to point defects, and enables more than

100,000 cycles of endurance and over 20

years of retention. In traditional Flash

technologies, insulator point defects may

increase over time as a result of repeated

program/erase cycles. This may eventually

lead to leakage pass-through that causes

the cell's entire charge to drain out. With

NROM technology, however, as charge is

stored in localized states, a defect that

causes one charge to leak does not imply

leakage of any other charges in its vicinity.

Added Value for All Applications
