LPC Super I/O for Desktop & Server

The W83527HG, a member of Nuvoton's LPC Super I/O product line, supports PS/2 interface, GPIO, hardware monitoring functions and Intel PECI.
The W83527HG monitors several critical parameters in PC hardware, including fan speeds and temperatures. In terms of temperature monitoring, the W83527HG adopts the Current Mode (dual current source) approach. The W83527HG also supports the SMART FAN control system, which makes the system more stable and user-friendly.
The W83527HG provides flexible I/O control functions through a set of 18 general purpose I/O (GPIO) ports. These GPIO ports may serve as simple I/O ports or may be individually configured to provide alternative functions.
The W83527HG supports Intel PECI (Platform Environment Control Interface)
The configuration registers inside the W83527HG support mode selection, function enable and disable, and power-down selection. Furthermore, the configurable PnP features are compatible with the plug-and-play feature in Windows, making the allocation of the system resources more efficient than ever.
