Description

SiS5595 is a highly integrated system I/O that constitutes a high performance, rich featured, yet glueless solution for both Pentium and Pentium II systems.

The SiS5595 PCI system I/O integrates the PCI-to-ISA bridge with the DDMA and PC/PCI DMA, Serial IRQ capability, the ACPI/Legacy PMU, the Data Acquisition Interface, the Universal Serial Bus host/hub interface, and the ISA bus interface, which contains the ISA bus controller, the DMA controllers, the interrupt controllers, and the Timers. It also integrates the Keyboard controller, and the Real Time Clock (RTC). The built-in USB controller, which is fully compliant to OHCI (Open Host Controller Interface), provides two USB ports capable of running full/low speed USB devices. The Data Acquisition Interface offers the ability of monitoring and reporting the environmental condition of the PC. It could monitor 5 positive analog voltage inputs, 2 Fan speed inputs, and one external temperature inputs. It also integrates the automatic power control logic to control the power ON/OFF for ATX power supply. In addition, SiS5595 also integrates the thermal detection and frequency ratio control logic for Pentium II CPU.
