Winbond Electronics Corp. announces its next generation Super I/O controller: the W83667HG. Following the success of the W83627EHG and W83627DHG family of devices, which have been highly regarded and widely adopted by major motherboard and desktop PC manufacturers, Winbond presents the W83667HG.

The device implements the latest Intel PECI (Platform Environment Control Interface) host and SST (Simple Serial Transport) client interfaces, and AMD SB-TSI interface. Intel PECI and AMD SB-TSI interfaces are used to detect CPU thermal condition. The independent VID I/O pins, targeting performance and gaming segments, are used to execute CPU overvoltage setting dynamically, which will improve CPU performance. Full function consumer IR (CIR), including receiver, learning and emitting functions, is supported by the device, and can be used for remote control applications, such as Microsoft Vista OS for Home Media Center. The device also provides serial peripheral interface (SPI) flash interface, so that the south bridge can communicate with the SPI flash through the LPC interface, and this adds the design flexibility. The highly integrated and feature-rich W83667HG is suited for the coming Intel Eaglelake platform and AMD AM3 platform designs.

In addition to the new features described above, W83667HG supports legacy I/O controller functionalities as well, including interfaces for keyboard and mouse, UART, parallel printer, floppy disk drive and GPIO. The device also performs system wake-up function from "S3" and "S5" ACPI states by keyboard, mouse or GPIO events. Meanwhile, Winbond has enhanced the performance of system hardware monitoring functions through advanced IC research and design. The device's dual current-source architecture provides improved temperature measurement accuracy. The fan speed control circuit is suitable for either DC- or PWM-fan. Winbond patented SMART FAN closed-loop fan speed control algorithms are also included. By monitoring temperature, voltage, fan speed (RPM) and controlling fan speed (PWM), the W83667HG ensures efficiency and reliability of motherboard and desktop PC applications.

The W83667HG feature set is said to be the most desirable for motherboard and desktop PC applications.
