R8A66597FP/DFP/BG ASSP (USB2.0 2 Port Host/1 Port Peripheral Controller) REJ03F0229-0101 Rev1.01 Oct 17, 2008 1 Overview 1.1 Overview The R8A66597 is a Universal Serial Bus (USB) Controller equipped with USB Host functions and Peripheral functions applicable for On-The-Go. When selecting the Host Controller function, it has two USB ports available for Hi-Speed, Full-Speed, and Low-Speed transfer compliant with USB Specification Revision 2.0. When selecting the Peripheral Controller function, it has one USB port available for Hi-Speed and Full-Speed transfer compliant with USB Specification www.DataSheet4U.com Revision 2.0. This controller has a built-in USB transceiver and is compatible with all the transfer types defined in USB Specification Revision 2.0. The internal buffer memory is 8.5K, and a maximum ten pipes can be used for transferring data. For Pipe1 to Pipe9, any endpoint address can be assigned matching the peripheral functions for communication or user system. Separate bus or multiplex bus can be selected for the CPU connection. A split bus interface (exclusively for the DMA interface) that is different from the CPU bus interface is provided and is suitable for systems demanding high-performance data transfer. 1.2 Features 1.2.1 • • • Built-in Host Controller and Peripheral Controller compatible with Hi-Speed USB Built-in USB Host Controller and Peripheral Controller Toggle between USB Host functions and Peripheral functions is possible according to what is written to the register Built-in USB transceiver 1.2.2 • • • • Low power consumption 1.5V core power consumes less power when operating With the installed Low Power Sleep Mode functions, less power is consumed when the USB is not in use, which is also applicable for portable devices Standby power consumption can be greatly reduced by keeping only the VIF power source ON when not using the USB function. Operational with a 3.3V single power supply using the internal 1.5V core power regulator 1.2.3 • Space-saving package Few external devices and space-saving package VBUS signal can be connected directly to the controller input pin Built-in D+ pull-up resistor (for Peripheral function) Built-in D+ and D- pull-down resistors (for Host function) Built-in D+ and D- terminating resistors (for Hi-Speed operations) Built-in D+ and D- output resistors (for Full-Speed and Low-Speed operations) Rev1.01 Oct 17, 2008 page 1 of 183 R8A66597FP/DFP/BG 1.2.4 • Compatible with all USB transfer types Compatible with all USB transfer types, including isochronous transfer Control transfer Bulk transfer Interrupt transfer (not compatible with high-bandwidth) Isochronous transfer (not compatible with high-bandwidth) 1.2.5 • Bus interface 16-bit CPU bus interface Compatible with 16-bit separate bus/16-bit multiplex bus Compatible with DMA transfer in 8-bit/16-bit access (slave function) • 8-bit split bus (exclusive for external direct memory access controller (DMAC)) interface • Built-in two DMA interface channels • DMA transfer provides 40MB/second high-performance data transfer www.DataSheet4U.com 1.2.6 • • • • • Pipe configuration Built-in 8.5KB buffer memory for USB communication Maximum of ten pipes can be selected (including default control pipe) Programmable pipe configuration Any endpoint address can be assigned to Pipe1 to Pipe9 Transfer conditions that can be written for each pipe Pipe0: Control transfer, single buffer fixed at 256 bytes Pipe1~Pipe2: Bulk transfer/Isochronous transfer, continuous transfer modes. programmable buffer size (specifiable up to 2K bytes per side, double buffer also specifiable) Pipe3~Pipe5: Bulk transfer, continuous transfer modes, programmable buffer size (specifiable up to 2K bytes per side, double buffer also specifiable) Pipe6~Pipe9: Interrupt transfer, single buffer fixed at 64 bytes 1.2.7 • • • • • Features when selecting Host functions Compatible with Hi-Speed (480Mbps), Full-Speed (12Mbps) and Low-Speed transfer (1.5Mbps) Several Peripheral devices can be connected through one tier hub Reset handshake auto response SOF and packet transmission schedule automation Transfer interval setup function for Isochronous and Interrupt transfer 1.2.8 • • • • • • • Features when selecting Peripheral functions Compatible with Hi-Speed (480Mbps) and Full-Speed transfer (12Mbps) Auto identification of Hi-Speed or Full-Speed operations according to reset handshake auto response Control transfer stage management function Device state management function Auto response function related to SET_ADDRESS request NAK response interrupt function (NRDY) SOF interpolation function 1.2.9 • • Functions that Provide On-The-Go Support Built-in ID pin and ID pin monitor bit enables determination of A-Device/B-Device at start-up Built-in control bit facilitates Host Negotiation Protocol 1.2.10 Other functions • • • • • • • • • Rev1.01 Compatible with the CPU of big-endian or little-endian according to the byte-endian swap function.
