Saifun’s SA25C family of SPI
devices provides small-sized,
cost-effective, low-power and
high-performance Serial EEPROM
memory chips for today’s market
needs. Using the patented Saifun
NROM
™
technology, the SA25C
devices contain two bits per cell,
which ensures minimal die size
and maximal growth within the
same package with increasing
densities.
Ease of use
EEPROM devices are easy for use
• All data handling is internally with no
need for external RAM
• No need for a Sector Erase followed by
a page write
Fastest Access Times
The SA25C family sets the industry speed
record for serial SPI EEPROMs:
• The 512Kb and 1Mb devices run at 10
MHz (as compared to the industry
standard of less than 5 MHz)
• The 2Mb device runs at 25 MHz
Minimal System Cost
System cost is affected by both footprint
and package cost. Saifun's 512Kb to 2Mb
SPI Serial EEPROM devices have the same
small footprint as the industry standard's
8-pin narrow SOIC packages, or leadless
MLF packages.
The devices' small footprint saves board
space and reduces system overhead cost.
Enables new features and capabilities to be
added to your products simply and easily,
without costly, time-consuming redesigns.
In addition, EEPROM usage eliminates the
need of data management by the system.
Easy Migration
The Saifun 512Kb to 2Mb SPI Serial EEPROM
devices have the industry's 128/256-byte
Page Write (as compared to the standard
larger Sector Erase, for example 256Kb).
This Page 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)
and Serial Flash Devices (512Kb to 2Mb,
emulating EEPROM) to the 512 Kb to 2Mb
SA25C 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
SA25C 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 SA25C family of devices addresses
various target markets:
Communications
• Fax, Modems and Answering Machines
• Smart Cellular phones with E-mail, PDA
• Telephone line cards, Routers and
Network interface cards
Computers
• Graphic and SCSI cards
• Network cards and Hard-Disk drives
• Mother board chipset
Consumer Applications
• Digital TVs and Set-Top boxes
• DVD players and Audio MP3 players
• Cameras and Mobile GPS
