The SL811HST-AXC is a 8-bit Embedded USB Host/Slave Controller capable of communicating in either full speed or low speed. The SL811HS interfaces to devices such as microprocessors, microcontrollers, DSPs or directly to a variety of buses such as ISA, PCMCIA and others. The SL811HS USB host controller conforms to USB Specification 1.1. The SL811HS incorporates USB Serial Interface functionality along with internal full or low speed transceivers. The SL811HS supports and operates in USB full speed mode at 12Mbps or in low speed mode at 1.5Mbps. When in host mode, the SL811HS is the master and controls the USB bus and the devices that are connected to it. In peripheral mode, otherwise known as a slave device, the SL811HS operates as a variety of full- or low speed devices.
