7.12.1.1 Features
7.12.1 USB device controller
7.12 USB interface
The Universal Serial Bus (USB) is a 4-wire bus that supports communication between a
host and one or more (up to 127) peripherals. The host controller allocates the USB
bandwidth to attached devices through a token-based protocol. The bus supports hot
plugging and dynamic configuration of the devices. All transactions are initiated by the
host controller.
The LPC1758/56/54 USB interface includes a device, Host, and OTG controller with
on-chip PHY for device and Host functions. The OTG switching protocol is supported
through the use of an external controller. Details on typical USB interfacing solutions can
be found in
The device controller enables 12 Mbit/s data exchange with a USB Host controller. It
consists of a register interface, serial interface engine, endpoint buffer memory, and a
DMA controller. The serial interface engine decodes the USB data stream and writes data
to the appropriate endpoint buffer. The status of a completed USB transfer or error
condition is indicated via status registers. An interrupt is also generated if enabled. When
enabled, the DMA controller transfers data between the endpoint buffer and the on-chip
SRAM.
