13 USB DEVICE CONTROLLER
OVERVIEW
Universal Serial Bus (USB) device controller is designed to provide a high performance full speed function controller
solution with DMA interface. USB device controller allows bulk transfer with DMA, interrupt transfer and control
transfer.
USB device controller supports:
— Full speed USB device controller compatible with the USB specification version 1.1
— DMA interface for bulk transfer
— Five endpoints with FIFO
EP0: 16byte (Register)
EP1: 64byte IN/OUT FIFO (dual port asynchronous RAM): interrupt or DMA
EP2: 64byte IN/OUT FIFO (dual port asynchronous RAM): interrupt or DMA
EP3: 64byte IN/OUT FIFO (dual port asynchronous RAM): interrupt or DMA
EP4: 64byte IN/OUT FIFO (dual port asynchronous RAM): interrupt or DMA
— Integrated USB Transceiver
FEATURE
— Fully compliant with USB Specification Version 1.1
— Full speed (12Mbps) device
— Integrated USB Transceiver
— Supports control, interrupt and bulk transfer
— Five endpoints with FIFO:
One bi-directional control endpoint with 16-byte FIFO (EP0)
Four bi-directional bulk endpoints with 64-byte FIFO (EP1, EP2, EP3, and EP4)
— Supports DMA interface for receive and transmit bulk endpoints. (EP1, EP2, EP3, and EP4)
— Independent 64byte receive and transmit FIFO to maximize throughput
— Supports suspend and remote wakeup function
NOTE
PCLK should be more than 20MHz to use USB Device Controller stably.
