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

x VBUS signal can be connected directly to the controller input pin

x Built-in D+ pull-up resistor (for Peripheral function)

x Built-in D+ and D- pull-down resistors (for Host function)

x Built-in D+ and D- terminating resistors (for Hi-Speed operations)

x Built-in D+ and D- output resistors (for Full-Speed and Low-Speed operations)
