LPC1769/68/67/66/65/64
32-bit ARM Cortex-M3 microcontroller
– Memory traffic optimized by buffering and pre-fetching.
• Enhanced Ethernet features:
– Receive filtering.
– Multicast and broadcast frame support for both transmit and receive.
– Optional automatic Frame Check Sequence (FCS) insertion with Cyclic
Redundancy Check (CRC) for transmit.
– Selectable automatic transmit frame padding.
– Over-length frame support for both transmit and receive allows any length frames.
– Promiscuous receive mode.
– Automatic collision back-off and frame retransmission.
– Includes power management by clock switching.
– Wake-on-LAN power management support allows system wake-up: using the
receive filters or a magic frame detection filter.
• Physical interface:
– Attachment of external PHY chip through standard RMII interface.
– PHY register access is available via the MIIM interface.
7.12 USB interface (LPC1769/68/66/65/64 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 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
Section 14.1.
Remark: The LPC1764 includes a device controller only.
7.12.1 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.
7.12.1.1 Features
• Fully compliant with USB 2.0 specification (full speed).
• Supports 32 physical (16 logical) endpoints with a 4 kB endpoint buffer RAM.
• Supports Control, Bulk, Interrupt and Isochronous endpoints.
