It features an integrated USB host stack, a system interface driver, on-chip USB signaling hardware, 32-bit generic system processor interface with DMA support, and on-the-fly host/function switching capability. The on-chip USB hardware features a USB transceiver, a serial interface engine SIE , a SIE controller, and an SOF generation block. It supports the physical and data link layer of the USB protocol whereas the USB transaction layer is implemented in firmware. In host mode, the integrated USB firmware consists of the Host USB Controller Driver HUSBCD running on the USB Controller USBC and the Host System Interface Controller Driver HSICD resident on the System Interface Controller SIC . The HUSBCD provides complete USB protocol management including device enumeration, transaction management, scheduling and frame management, and bus reclamation. The HSICD serves as an interface between the HUSBCD and applications resident on the external system processor. It handles all of the high-level data flow management during a USB transaction. Together, the HUSBCD and the HSICD deliver complete USB host operations autonomously, without the intervention of the system processor. Pin Configuration The AT43USB370 communicates with the external system processor through its generic 32-bit host processor interface. This system interface contains 2 Kbytes of FIFO and a DMA engine designed to ensure maximum bus utilization. The automatic USB retry mechanism minimizes data traffic across the system interface. As a function, the AT43USB370 operates in full-speed mode. It supports one control endpoint and a maximum of six programmable maximum packet size and endpoint type endpoints. The internal USB controller runs the function firmware that manages USB enumeration and data flow control without system processor intervention. Communication between the AT43USB370 firmware and applications resident in the system processor is realized through a small set of ANSI C compliant, system interface Application Protocol Interfaces APIs . This API set encapsulates the complete USB functionality. It is used as the basic building blocks for constructing application specific USB device drivers of any type. The AT43USB370, with its highly integrated USB hardware/firmware architecture, not only hides the complexity of the traditional USB design, but also frees system resources from being burdened by timing critical USB activities. It is an ideal solution for point-to-point USB connectivity in the resource constrained embedded environment.
