The USB interface is compliant with the USB2.0 standard for a full speed (12Mbps)

endpoint device. Together with VUSB and GND it creates a standard USB 4-pin

interface. VUSB (VBUS in the USB standard) is nominally 5.0V.

USB is not available on legacy variant GR64 devices (GR64001

products). On these products, the signal connections can be left un-

terminated.

NOTE

The USB interface has the following features:

• Full-speed (12M bits/s) device operation

• 16 unidirectional endpoints

• Each endpoint capable of supporting control, interrupt, isochronous and bulk

transfer

• Programmable endpoint types and FIFO sizes and internal 1120-byte logical

(2240-byte physical for dual-packet mode) shared FIFO storage allow a wide

variety of configurations.

• Dual-packet mode of FIFOs reduces latency

• USB reset can be programmed to clear device address.
