Flash-based single-chip controller targets portable apps


SUNNYVALE, Calif.—Aimed at portable devices, SST (Silicon Storage Technology, Inc.) has developed a mobile platform controller that combines a keyboard controller, power management controller and 8-Mbits of LPC Firmware Flash in a single device.

The SST79LF008 mobile platform controller is designed to provide higher performance than a standard 8051 microcontroller. Using SST's proprietary SuperFlash technology, the SST79LF008 mobile platform controller features an 8-Mbit LPC Firmware Flash and an SST-enhanced high-performance 8051 microcontroller core with three or six-clock machine cycle and 33-MHz max operating clock frequency. A three-wire Alternate LPC (aLPC) interface allows for rapid factory programming of the entire flash memory with Auto Address Increment Mode (AAI).

The 8-Mbit on-chip shared SuperFlash memory in the controller provides storage for system BIOS as well as keyboard and embedded controller firmware. The 4-KByte sectors and 64-KByte blocks allow flexible erase capabilities. All standard LPC Firmware memory functions are supported in addition to advanced features such as LPC 1.1 multi-byte read/write protocols.

“For mobile designers, board space, power consumption and reliability are critical success factors,” said Michael Briner, senior vice president of SST's Application Specific Product Group, in a statement. “SST leveraged its leading-edge BIOS flash and 8051 technologies in developing the mobile platform controller. This device is fully compatible with the most advanced LPC specification and replaces designer's current two or three chip solutions with a single chip.”

The SST79LF008 mobile platform controller featuring 8-Mbit LPC Firmware Flash is available now in both LQFP and TFBGA 176-pin packages. Pricing for the mobile platform controller is $3.50 in 10K unit quantities.
