The main features of this Ethernet controller are the following:
Embedded 16 Kbyte FIFO for packet buffers
Support burst-mode read for highest performance applications
Configurable interrupt pin with programmable hold-off timer
Compatible with IEEE 802.3, 802.3u standards
Integrate Fast Ethernet MAC/PHY transceiver in one chip
10Mbps and 100Mbps data rate
Full and half duplex operations
10/100Mbps Auto-negotiation operation
Twisted pair crossover detection and auto-correction (HP Auto-MDIX)
IEEE 802.3x flow control for full-duplex operation
Wake-on-LAN capabilities
LED pins for various network activity indications
The Ethernet controller is connected to CS5#. Its programmable polarity interrupt output is
connected to the signal GPIO1_9.
The module does not have a transformer and Ethernet connector.
The module provides two status signals for activity and link LEDs.
I2C
The module provides two I2C interfaces. The I2C interfaces operate up to 400Kbps, depending
on pad loading and timing. The I2C system is a true multiple master bus including arbitration
and collision detection.
The I2C port 2 interface is available on the development board (header P22). Two 2K2 pull-up
resistors are provided on the module.
The I2C port 1 interface is available through the main module connectors (J1 and J2) as well
as on the corresponding signal rail connectors (J25 and J26), multiplexed with other
interface functionality. The development board does not provide a dedicated header for
access to I2C port 1.
The I2C port 1 signals are available through the main module connectors as outlined below:
I2C1_SDA:
– J1.141 - EIM_D16 (used on the module for external Ethernet controller, if present)
– J2.111 - SPI1_MOSI (used on the module as communication channel for Freescale PMIC)
– J2.86 - SD2_CLK (used on the module as communication channel for Wireless LAN
interface, if present)
I2C1_SCL:
– J1.144 - EIM_D19 (used on the module for external Ethernet controller, if present)
