R8A66597FP Datasheet | Renesas

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 pliant 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 pliant with USB Specification .. Revision 2.0. This controller has a built-in USB transceiver and is patible 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 munication 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 - - - Built-in Host Controller and Peripheral Controller patible 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 - - - - 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 - Space-saving package Few external devices and space-saving package VBUS signal can be connected directly to the controller input pin...
