Embedded controllers 'first' to support IR, SPI

Insisting that wireless communications in personal-area networking goes beyond headline-grabbing Bluetooth, UWB and Zigbee, Winbond Electronics Corp. is rolling out two embedded controllers that it calls the world's "first" to support both IR and SPI flash.

Taiwan's Winbond is out to show that traditional IR technology continues to have legs. Its WPC8768 and WPC8769 are RISC-based controllers that support Microsoft Corp.'s new Vista OS. The devices also integrate a module that supports both a Fast IR (FIR) port and Media Center-compliant consumer IR port. The module enables low-cost, remote-control capabilities and eliminates the need for external IR devices, Winbond said.

The Infrared Data Association (IrDA), a non-profit organization that defines specifications for IR wireless communications, said IR technology facilitates point-to-point wireless communication between electronic devices using directed half-duplex serial IR communications links. FIR technology enables data transmissions up to 4Mbps, IrDA said.Designed for mobile PC platforms, Winbond's WPC876x devices are suitable for a range of small-form-factor systems. The devices offer such keyboard and mouse controller functions as internal keyboard matrix scan and decode.

16bit RISC
Both devices use a proprietary 16bit RISC processor with a 4Mbyte external address space. In addition, their chips incorporate general-purpose I/Os, timers, UARTs, SMBus interfaces, PS/2 interfaces, ADCs and DACs. They also support a shared BIOS flash option.

Winbond is offering designers a complete set of utilities and software with the embedded controllers, including embedded controller firmware and module-specific drivers. The WPC8768 and WPC8769 are each available in a 128-pin LQFP. Prices depend on the configuration.
