Product data sheet
7.9.1.1 Features
7.9.1 Full-speed USB device controller
7.9 USB interface (LPC1342/43 only)
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 LPC1342/43 USB interface is a device controller with on-chip PHY for device
functions.
The device controller enables 12 Mbit/s data exchange with a USB Host controller. It
consists of a register interface, serial interface engine, and endpoint buffer memory. 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.
