Low jitter PLL
Within the USB Hosts and device a local Low Jitter PLL is provided to meet the USB2.0
specification requirements.
It supports the 480 Mbps high-speed (HS) for USB 2.0, as well as the 12 Mbps full-
speed (FS) and the low-speed (LS) for USB 1.1.
It supports 16 physical endpoints and proper configurations to achieve logical
endpoints.
Integrated USB transceiver (PHY)
Local FIFO having size of 4 Kbyte shared among all the endpoints.
Both DMA mode and Slave-Only mode supported.
In DMA mode, the UDC supports descriptor-based memory structures in application
memory.
In both modes, an AHB slave is provided by UDC-AHB, acting as programming
interface to access to memory-mapped control and status registers (CSRs);
An AHB master for data transfer to system memory is provided, supporting 8, 16, and
32-bit wide data transactions on the AHB bus.
A USB Plug Detect (UPD) which detects the connection of a cable.
