AM261 devices introduce a USB module that supports USB 2.0 in host, device, and dual role device configurations. In USB host mode, high-speed (HS, 480Mbps), full-speed (FS, 12Mbps), and low-speed (LS, 1.5Mbps) data rates are supported. In USB device mode, only high-speed (HS, 480Mbps) and full-speed (FS, 12Mbps) data rates are supported. The USB module supports all USB transfer types - control, bulk, interrupt, and isochronous.
Features include 15 IN (receive) and 15 OUT (transmit) endpoints (EPs) along with an EP0 endpoint that is bidirectional. USB descriptor caching and data pre-fetch is offered to streamline device enumeration.
For applications that require the USB host provides the 5V output on VBUS, an external charge pump to be controlled by the USB module is required.
