6.20 Universal Serial Bus OTG Controller (USB0) [USB2.0 OTG]
The USB2.0 peripheral supports the following features:
• USB 2.0 peripheral at speeds high speed (HS: 480 Mb/s) and full speed (FS: 12 Mb/s)
• USB 2.0 host at speeds HS, FS, and low speed (LS: 1.5 Mb/s)
• All transfer modes (control, bulk, interrupt, and isochronous)
• 4 Transmit (TX) and 4 Receive (RX) endpoints in addition to endpoint 0
• FIFO RAM
– 4K endpoint
– Programmable size
• Integrated USB 2.0 High Speed PHY
• Connects to a standard Charge Pump for VBUS 5 V generation
• RNDIS mode for accelerating RNDIS type protocols using short packet termination over USB
Important Notice: The USB0 controller module clock (PLL0_SYSCLK2) must be greater than 30 MHz for
proper operation of the USB controller. A clock rate of 60 MHz or greater is recommended to avoid data
throughput reduction.
