6.10 High-speed Universal Serial Bus 2.0 On-The-Go (OTG)

The USB OTG module allows the LPC3130/3131 to connect directly to a USB host such

as a PC (in device mode) or to a USB device in host mode. In addition, the LPC3130/3131

has a special, built-in mode in which it enumerates as a Device Firmware Upgrade (DFU)

class, which allows for a (factory) download of the device firmware through USB.

This module has the following features:

• Complies with Universal Serial Bus specification 2.0.

• Complies with USB On-The-Go supplement.

• Complies with Enhanced Host Controller Interface Specification.

• Supports auto USB 2.0 mode discovery.

• Supports all high-speed USB-compliant peripherals.

• Supports all full-speed USB-compliant peripherals.

• Supports software Host Negotiation Protocol (HNP) and Session Request Protocol

(SRP) for OTG peripherals.

• Contains UTMI+ compliant transceiver (PHY).

• Supports interrupts.

• This module has its own, integrated DMA engine.
