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. 

•

  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: 128byte IN/OUT FIFO (dual port asynchronous RAM): interrupt or DMA 
EP2: 128byte IN/OUT FIFO (dual port asynchronous RAM): interrupt or DMA 
EP3: 128byte IN/OUT FIFO (dual port asynchronous RAM): interrupt or DMA 
EP4: 128byte IN/OUT FIFO (dual port asynchronous RAM): interrupt or DMA

  Integrated USB Transceiver 

 

—  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 128-byte FIFO (EP1, EP2, EP3, and EP4) 

—  Supports DMA interface for receive and transmit bulk endpoints. (EP1, EP2, EP3, and EP4) 

—  Independent 128-byte receive and transmit FIFO to maximize throughput 

—  Supports suspend and remote wakeup function 

 

NOTE 

PCLK should be more than 20MHz to use USB Controller in stable condition.
