Hi-speed USB 2.0 and 10/100 Mbit Ethernet
The TE0726-03 has on-board SMSC LAN9514 controller featuring USB 2.0 hub and 10/100 Mbit Ethernet controller. USB hub has four downstream ports and one upstream port, fully compliant with Universal Serial Bus Specification Revision 2.0. HS (480 Mbps), FS (12 Mbps), and LS (1.5 Mbps) compatible. Upstream port is connected to the SMSC USB3320 hi-speed USB 2.0 ULPI transceiver which has full support for the optional On-The-Go (OTG) protocol.
High-Performance 10/100 Ethernet controller integrated into the same LAN9514 IC is fully compliant with IEEE802.3/802.3u standards, has integrated Ethernet MAC and PHY and supports both 10BASE-T and 100BASE-TX media.
256-byte EEPROM is connected via Microwire to the LAN9514 chip to store MAC address.
USB to JTAG/UART
The TE0726-03 has on-board high-speed USB 2.0 to UART/FIFO FT2232H controller from FTDI with external connection to micro-USB connector J1. There is also a 256-byte EEPROM wired to the FT2232H chip via Microwire bus which holds pre-programmed license code to support Xilinx programming tools.
Do not access the FT2232H EEPROM using FTDI programming tools, doing so will erase normally invisible user EEPROM content and invalidate stored Xilinx JTAG license. Without this license the on-board JTAG will not be accessible any more with any Xilinx tools. Software tools from FTDI website do not warn or ask for confirmation before erasing user EEPROM content.
4-Channel I2C Multiplexer
Zynq MIO pin 48 (MUX_SCL) and pin 49 (MUX_SDA) are connected to the 4-channel I2C multiplexer chip TCA9544A from Texas Instruments having I2C address of 0x70. It has four slave I2C channels which are routed as follows:
|0||Connector J8, pin 27 (ID_SDA) and pin 28 (ID_SCL).|
|1||DSI connector J4, pin 12 (DSI_SDA) and pin 11 (DSI_SCL).|
|2||HDMI connector J6, pin 16 (SDA) and pin 15 (SCL).|
|3||CSI-2 camera connector J3, pin 14 (CSI_SDA) and pin 13 (CSI_SCL).|
Each slave channel of TCA9544A has its own dedicated interrupt signal in order for the master to detect an interrupt on the INT output pin that can result from any of the slave devices connected to the INT0-INT3 input pins.
Xilinx Zynq devices in CLG225 package do not support SD Card boot directly from ROM bootloader.
At least FSBL must be loaded from on-board SPI Flash, later all boot process can continue from SD Card. The easiest solution is to let FSBL to load bitstream and u-boot from SPI Flash, and then let u-boot to load Linux or any other OS image from SD Card.

Power and Power-On Sequence
To power-up a module, 5.0V power supply with minimum current capability of 1A is recommended.
TE0726 needs one single power source via micro-USB jack J1. However it is recommended to not use any USB equipment below USB standard 2.0 to power the module. Also two-pin header J5 can be used to provide power source if needed.
There is no specific power-on sequence.

If TE0726 module is powered by micro-USB connector J1 VBUS pin, which voltage level is controlled by supplying host according to the USB standards and should be 5V, there is not much user can control here if using standard USB equipment. However, user can also power the module by applying voltage to the J5 connector from other external sources. In both cases following maximum voltage ratings apply.
