Take your designs to a higher level with the power of Saifun NROM™ memory

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

The SA25F family of devices addresses
various target markets:

Communications

• Fax and Answering Machines

• Smart Cellular phones with E-mail, PDA

• DSL/Cable modem, Routers and
Network interface cards

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.
