General description
The SAF1761 is a single-chip Hi-Speed Universal Serial Bus (USB) On-The-Go (OTG)
Controller integrated with advanced NXP slave host controller and the peripheral
controller.
The Hi-Speed USB host controller and peripheral controller comply to
Ref. 1 “Universal
Serial Bus Specification Rev. 2.0”
and support data transfer speeds of up to 480 Mbit/s.
The Enhanced Host Controller Interface (EHCI) core implemented in the host controller is
adapted from
Ref. 2 “Enhanced Host Controller Interface Specification for Universal Serial
Bus Rev. 1.0”
. The OTG controller adheres to
Ref. 3 “On-The-Go Supplement to the USB
Specification Rev. 1.3”
.
The SAF1761 has three USB ports. Port 1 can be configured to function as a downstream
port, an upstream port or an OTG port; ports 2 and 3 are always configured as
downstream ports. The OTG port can switch its role from host to peripheral, and
peripheral to host. The OTG port can become a host through the Host Negotiation
Protocol (HNP) as specified in the OTG supplement.
