SUNNYVALE, Calif., Sept. 10 /PRNewswire-FirstCall/ -- SST (Silicon Storage Technology, Inc.), a leader in flash memory technology, today announced a new addition to the company's popular SuperFlash-based FlashFlex family of 8-bit, 8051-compatible microcontrollers, the SST89V54RD-33-C-QIF. Leveraging the company's innovative packaging technology, the new SST89V54RD is available in a 6mm x 6mm WQFN package, making it the smallest 8051-based microcontroller currently on the market. The device's miniature size and low power consumption are ideal for small form factor mobile applications, such as notebook PCs, MP3 players and GPS systems, as well as home entertainment devices including HDMI products. Additionally, the SST89V54RD supports in-system programming (ISP) and in-application programming (IAP), which provide a variety of benefits to device manufacturers and consumers alike.

"As the sophistication of mobile devices increases, size reduction and low power consumption become even larger issues for product design teams," said Paul Lui, senior vice president of the Standard and Special Product Group at SST and president of SST China. "The new thin and powerful SST89V54RD was designed to help our customers meet the size, power and performance requirements of next-generation portable consumer electronic devices."

In addition to a tiny 6mm x 6mm footprint, the WQFN package offers an extremely low-profile nominal package height of only 0.7mm (maximum total thickness of 0.8mm), making the new SST89V54RD well suited for height-constrained mobile applications.

In-Field Re-Programmability Through IAP and ISP

Like all of SST's FlashFlex microcontrollers, the SST89V54RD supports both IAP and ISP, enabling the user to update the flash device in the field or in an application. Both IAP and ISP lower cost and improve time-to-market for manufacturers, while bringing enhanced user experiences and convenience to consumers. These re-programming features also have a significant role in enabling increased functionality, such as remote diagnostics and product monitoring, in network- or Internet-enabled devices.

Pricing and Availability

Samples of the SST89V54RD-33-C-QIF FlashFlex microcontroller are available now. Pricing starts at $1.20 in 10K unit quantities. For more information about this or other SST products, please contact an SST sales representative, or visit the company's Web site at http://www.sst.com/.
