38. USB High Speed Device Port (UDPHS)
38.1

6438G–ATARM–19-Apr-11
Description
Embedded Characteristics
The USB High Speed Device Port (UDPHS) is compliant with the Universal Serial Bus (USB),
rev 2.0 High Speed device specification.
Each endpoint can be configured in one of several USB transfer types. It can be associated with
one, two or three banks of a dual-port RAM used to store the current data payload. If two or
three banks are used, one DPR bank is read or written by the processor, while the other is read
or written by the USB device peripheral. This feature is mandatory for isochronous endpoints.
The device features USB communication ports as follows:
USB Host Port A is directly connected to the first UTMI transceiver.
The Host Port B is multiplexed with the USB device High speed and connected to the second
UTMI port. The selection between Host Port B and USB device high speed is controlled by a the
UDPHS enable bit located in the UDPHS_CTRL control register.
Figure 38-1. USB Selection
• 2 Ports USB Host full speed OHCI and High speed EHCI
• 1 Device High speed
• USB V2.0 high-speed compliant, 480 MBits per second
• Embedded USB V2.0 UTMI+ high-speed transceiver shared with UHP HS.
• Embedded 4-KByte dual-port RAM for endpoints
• Embedded 6 channels DMA controller
• Suspend/Resume logic
• Up to 2 or 3 banks for isochronous and bulk endpoints
• Seven endpoints:
– Endpoint 0: 64 bytes, 1 bank mode
– Endpoint 1 & 2: 1024 bytes, 2 banks mode, High Bandwidth, DMA
– Endpoint 3 & 4: 1024 bytes, 3 banks mode, DMA
– Endpoint 5 & 6: 1024 bytes, 3 banks mode, High Bandwidth, DMA
