Product Overview

SUPER I/O Famiy

The LS601x is a highly integrated Super l/O using the Low Pin Count interface or eSPl interface, and monitors several critical parameters in PC hardware, including power supply voltages, fan speeds, and temperatures. It supports ARGB coloful LED. The devices are super I/O controllers with an eSPI/LPC interface and include an KB/MS interfaces controller, printer interfaces controller, hardware monitoring capabilities, reset generation, enhanced security features, power control logic and multiple serial ports, etc. These features make the LS6xx suitable for a wide range of applications such as desktop computers, servers, industrial computers, workstations and so on.
