• Manufacturer Part Number: HD6417660
• Description: Renesas 32-Bit RISC Microcomputer
• Manufacturer: RENESAS [Renesas Technology Corp]

This LSI incorporates an USB function controller (USBF).
20.1
• UDC (USB device controller) supporting USB 1.1 processes incorporated USB protocol
• Transfer speed: Full-speed
An arbitrary endpoint configuration can be set by specifying the endpoint number used by the
USB host and the endpoint FIFO number (transfer method and transfer direction are fixed)
provided by this USB function controller via the EPIRn0 to EPIRn5 registers.
• Interrupt requests: generates various interrupt signals necessary for USB
• Clock: Selection of internal system clock/external input (48 MHz) by means of EXCPG
• Power-down mode
• Power mode: Self-powered, bus-powered

automatically.
Automatic processing of USB standard commands for endpoint 0 (some commands and
class/vendor commands require decoding and processing by firmware)
transmission/reception
Power consumption can be reduced by stopping UDC internal clock when USB cable is
disconnected
Automatic transition to/recovery from suspend state
