MCS9990 is a single lane multi function PCI Express to 4 dedicated USB2.0 host controllers, dedicated bandwidth per port, allowing 4 dedicated USB2.0 host controllers share 2.5Gbps wide PCI Express bus bandwidth. It supports two modes of operation - USB host mode and OTG mode, selectable through device mode select pins. The USB host mode supports four USB2.0 host ports with four dedicated USB host Controllers. The OTG mode supports two USB2.0 host ports, one USB OTG port and provision to select GPIO or ISA interface. The four USB2.0 host ports are integrated with on-chip transceivers and support four dedicated Enhanced Host Controller Interface (EHCI) and four dedicated Open Host Controller Interface (OHCI). The USB OTG port is integrated with OTG PHY and supports host and device operations. The provisional ISA interface supports up to four serial ports and/or up to two parallel ports. The provisional 24 GPIO pins are programmable as an input or output.
