LPC2939
ARM9 microcontroller with CAN, LIN, and USB
6.10.2
Clock description
The DMA controller is clocked by CLK_SYS_DMA derived from BASE_SYS_CLK, see
Section 6.7.2
.
6.11 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 bus supports hot plugging and dynamic
configuration of the devices. All transactions are initiated by the Host controller.
The LPC2939 USB interface includes a device and OTG controller with on-chip PHY for
device. The OTG switching protocol is supported through the use of an external controller.
Details on typical USB interfacing solutions can be found in
Section 10.2
.
6.11.1
USB device controller
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.
The USB device controller has the following features:
Fully compliant with
USB 2.0 specification (full speed)
Supports 32 physical (16 logical) endpoints with a 2 kB endpoint buffer RAM
Supports Control, Bulk, Interrupt and Isochronous endpoints
Scalable realization of endpoints at run time
Endpoint Maximum packet size selection (up to USB maximum specification) by
software at run time
Supports SoftConnect and GoodLink features
While USB is in the Suspend mode, the LPC2939 can enter the Power-down mode
and wake up on USB activity
Supports DMA transfers with the on-chip SRAM blocks on all non-control endpoints
Allows dynamic switching between CPU-controlled slave and DMA modes
Double buffer implementation for Bulk and Isochronous endpoints
6.11.2
USB OTG controller
USB OTG (On-The-Go) is a supplement to the USB 2.0 specification that augments the
capability of existing mobile devices and USB peripherals by adding host functionality for
connection to USB peripherals.
The OTG Controller integrates the device controller, and a master-only I
2
C interface to
implement OTG dual-role device functionality. The dedicated I
2
C interface controls an
external OTG transceiver.
The USB OTG controller has the following features:
