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

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.

Built-in Host Controller and Peripheral Controller compatible with Hi-Speed USB

Low power consumption

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)

also applicable for portable devices

USB function.

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

1.5V 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

Standby power consumption can be greatly reduced by keeping only the VIF power source ON when not using the

Operational with a 3.3V single power supply using the internal 1.5V core power regulator
