LPC435x/3x/2x/1x
32-bit ARM Cortex-M4/M0 microcontroller
7.18.5 High-speed USB Host/Device/OTG interface (USB0)
Remark: USB0 is available on the following parts: LPC435x, LPC433x, LPC432x. USB0
is not available on the LPC431x parts.
The USB OTG module allows the LPC435x/3x/2x/1x to connect directly to a USB Host
such as a PC (in device mode) or to a USB Device in host mode.
7.18.5.1 Features
• Contains UTMI+ compliant high-speed transceiver (PHY).
• 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.
• Supports interrupts.
• Supports Start Of Frame (SOF) frame length adjust.
• This module has its own, integrated DMA engine.
• USB interface electrical test software included in ROM USB stack.
7.18.6 High-speed USB Host/Device interface with ULPI (USB1)
Remark: USB1 is available on the following parts: LPC435x and LPC433x. USB1 is not
available on the LPC432x and LPC431x parts.
The USB1 interface can operate as a full-speed USB Host/Device interface or can
connect to an external ULPI PHY for High-speed operation.
