Product data sheet
7.10.1 Features
7.11.1 Features
7.11 Ethernet
Additionally, any pin on Port 0 and Port 2 (total of 42 pins) providing a digital function can
be programmed to generate an interrupt on a rising edge, a falling edge, or both. The
edge detection is asynchronous, so it may operate when clocks are not present such as
during Power-down mode. Each enabled interrupt can be used to wake up the chip from
Power-down mode.
Remark: The Ethernet controller is available on parts LPC1769/68/67/66/64. The
Ethernet block supports bus clock rates of up to 100 MHz (LPC1768/67/66/64) or 120
MHz (LPC1769). See
The Ethernet block contains a full featured 10 Mbit/s or 100 Mbit/s Ethernet MAC
designed to provide optimized performance through the use of DMA hardware
acceleration. Features include a generous suite of control registers, half or full duplex
operation, flow control, control frames, hardware acceleration for transmit retry, receive
packet filtering and wake-up on LAN activity. Automatic frame transmission and reception
with scatter-gather DMA off-loads many operations from the CPU.
The Ethernet block and the CPU share the ARM Cortex-M3 D-code and system bus
through the AHB-multilayer matrix to access the various on-chip SRAM blocks for
Ethernet data, control, and status information.
The Ethernet block interfaces between an off-chip Ethernet PHY using the Reduced MII
(RMII) protocol and the on-chip Media Independent Interface Management (MIIM) serial
bus.

Bit level set and clear registers allow a single instruction to set or clear any number of
bits in one port.
Direction control of individual bits.
All I/O default to inputs after reset.
Pull-up/pull-down resistor configuration and open-drain configuration can be
programmed through the pin connect block for each GPIO pin.
Ethernet standards support:
– Supports 10 Mbit/s or 100 Mbit/s PHY devices including 10 Base-T, 100 Base-TX,
– Fully compliant with IEEE standard 802.3.
– Fully compliant with 802.3x full duplex flow control and half duplex back pressure.
– Flexible transmit and receive frame options.
– Virtual Local Area Network (VLAN) frame support.
Memory management:
– Independent transmit and receive buffers memory mapped to shared SRAM.
– DMA managers with scatter/gather DMA and arrays of frame descriptors.
– Memory traffic optimized by buffering and pre-fetching.
100 Base-FX, and 100 Base-T4.
