Serial Flash devices are smaller and
more frugal
SPI serial Flash memory devices boast the industry's smallest form factor and lowest power consumption.
Silicon Storage Technology has unveiled a new family of SPI serial Flash memory devices that boast the industry's smallest form factor and lowest power consumption The new SST25WFxxx family is ideal for battery-powered, space- and height-constrained portable applications including wireless networks such as ZigBee, Bluetooth, Wi-Fi, camera modules, portable media players, remote controls and portable VoIP products

The SST25WFxxx family continues SST's legacy of innovation in serial Flash technology and expands the company's presence in the high-volume portable electronics market.
Based on SST's proprietary SuperFlash technology, the first products available in the SST25WFxxx family are offered in densities of 512Kbit to 2Mbit, with plans to introduce higher densities in 2007.
The 25WFxxx serial Flash devices feature single supply voltage of 1.65 to 1.95V for read and write operations.

The products in the 34WA series use a 6 x 8 x 1mm semiconductor package, making them the smallest address/data bus multiplex combination memory devices available on the market today.
The maximum active power consumption for both read and write operations is less than half that of the lowest power 3V products on the market.
Active read currents are 9mA (typical at 20MHz), standby currents are only 2uA and maximum write currents are 15mA for both program and erase operations.
With this performance, the SST25WFxxx family achieves the lowest voltage and lowest standby current consumption in the industry for SPI serial Flash.
Utilising SST's low-power SPI serial Flash memory devices in portable electronic systems enables customers to extend battery life in their portable applications, while the densities allow for more content and additional features to be incorporated into mobile systems.
The SST25WFxxx family of devices is available in both an industry-standard SOIC package and SST's Z-Scale package (XFBGA), which is a true wafer-level package, utilising multi-layer metal interconnect and routing techniques.
With a maximum total height of only 0.4mm and an area as small as 3mm2 (depending on memory density), the Z-Scale package minimises required board real estate and maximises overhead clearance in aggressive physical product designs.
For the past six years, SST has been leading the evolution of serial Flash technology.
The company's serial Flash product portfolio is one of the broadest in the industry and has gained widespread adoption in optical disk drives, hard disk drives, desktop PCs and notebook BIOS, printers, LCD monitors, graphic cards and other high-volume markets.
The new SST25WFxxx family extends the benefits of serial Flash technology, which includes reductions in chipset pin counts, board space, power consumption and cost, to a wider range of battery-powered, small form factor wireless electronics.
According to data from Web-Feet Research, by the year 2009, serial Flash device revenue will reach $1 billion.
In addition, by 2007, unit shipments of serial Flash will reach 1 billion, representing 30% of the overall NOR Flash shipments.
"The introduction of the SST25WF family reinforces SST's commitment to the NOR Flash memory market", said Douglas Lee, Vice President, Applications Specific Memory Product Group, SST.
"As the market continues its trend toward lower voltage devices, no other serial Flash product on the market today achieves the combination of low power with high performance and small size that our SST25WF family delivers".
"Consumer demand for small, handheld wireless devices shows no signs of slowing, and we believe our new SST25WF family of serial Flash devices is well positioned to serve this market".
The first product available in the SST25WFxxx family is the 1Mbit SST25WF010.
Pricing for the SST25WF010 starts at US $0.70 in 10,000-unit quantities.
The device is sampling now, with volume production expected to begin by the end of the year.
Please contact an SST sales representative for product pricing.
All products in the family are lead free (non-Pb), RoHS compliant and are also available in industrial grade versions.
