MCS9990
MCS9990 is a single lane multi function PCI Express to USB2.0 Host Controller. 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. 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 supports Enhanced Host Controller Interface (EHCI) and Open Host Controller Interface (OHCI). The USB OTG Port is integrated with OTG PHY and supports host and device operations. MCS9990 is ideally suited for embedded applications for peripheral expansion, Desktop PC and Notebook applications, such as add-in Cards / Express Cards for USB Ports expansion. The PCI Express interface of MCS9990 is fully compliant with PCI Express base 1.1 specifications. The provisional ISA interface supports up to four serial ports and/or up to two parallel ports. The provisional 24 pin GPIO pins are programmable as an input or output.
