Original Press Release:
SST Expands 1.8V Serial Flash Product Portfolio to Support Emerging Design Challenges in Shrinking Portable Electronic Devices
Addition of Low-Power, Small Size 4-Mbit SPI Serial Flash Device Improves Performance, Reliability and Battery Life of Handheld Products
SUNNYVALE, Calif., Aug. 11 -- SST (Silicon Storage Technology, Inc.) (NASDAQ:SSTI), a leader in flash memory technology, today announced the SST25WF040 device, the company's newest addition to its widely adopted 1.8V 25WF Series SPI serial flash memory family. The 4-Mbit, small form factor SST25WF040 is ideal for battery-powered, space- and height- constrained mobile applications where performance, reliability and low-power consumption are crucial to product success. The SST25WF040 continues SST's commitment to provide the industry with innovative flash memory technology that addresses the unique design requirements of the high-volume portable electronics market.
The SST25WF040 extends all the benefits of serial flash technology, including reductions in chipset pin counts, board space, power consumption and cost, to a wider range of battery-powered, small form factor wireless electronics. SST is the only company to offer a full 1.8V serial flash product portfolio with densities ranging from 512 Kbit to 4 Mbit.
The SST25WF040 has a full voltage range from 1.65V to 1.95V for read and write operations and a fast read speed of 40 MHz. The maximum active power consumption for both read and write operations is significantly less than that of the lowest power 3V products currently on the market. Active read currents are 4 mA (typical at 40 MHz), standby currents are only 2 microamps (typical) and maximum write currents are 10 mA for both program and erase operations. With this performance, the 25WF Series offers the lowest voltage and lowest standby current consumption in the industry for SPI serial flash. Customers utilizing the SST25WF040 will increase the battery life in their portable applications and will be able to add more content and features into their mobile systems.
The SST25WF040 is rated for industrial temperatures (-40 degrees to +85 degrees Celsius) and offers 100,000 read/write cycles minimum per memory block for high-endurance applications. The device is available in an industry-standard SOIC package with other smaller package options available later this year. In addition, the device is offered as Known Good Die (KGD).
According to Leon Wong, business unit director, Memory Products Group, SST, "Consumers want ever smaller handheld devices with longer battery life. This presents a challenge for design engineers who are trying to meet size and power reductions while still improving product performance and functionality. SST has upheld its commitment by providing serial flash memory solutions that meet this demand and shall continue to innovate to address market requirements."
Pricing and Availability
The SST25WF040 is currently available in volume production. Pricing for the device is $1.15 each in 10K unit quantities. All products in the 25WF Series are lead free (non Pb) and RoHS compliant.
