On-board Peripherals

USB to JTAG and UART bridge

TE0703 has on-board USB JTAG and UART solution based on UART/FIFO controller from FTDI (U4). FTDI EEPROM is pre-programmed with 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.

JTAG and UART signals along with some more FTDI IOs are routed to the CPLD. See CPLD Firmware TE0703 CPLD - CC703S#CC703S for further description.

SD IO Levelshifter

SD IO levelshifter (U2) is used in congntion with jumper J11 to select the correct SD IO interface voltage of the SoM. 

I2C Repeater

For power sequence reasons the I2C bus is routed via a repater (U7) to to ensure no IOs of the SoM are driven before M3.3VOUT is up.


There are four on-board LEDs. D3 and D4 are  connected to the B2B connector JB2 pins FLED1 and FLED2 respectively and can be read by CPLD firmware. See TE0703 CPLD - CC703S#CC703S-LED.

TE0703 Jumper Settings

Take care of the VCCO voltage ranges of the  particular PL IO-banks (HR, HP) of the mounted SoM, otherwise damages may occur to the FPGA. Therefore, refer to the TRM of the mounted SoM to get the specific information of the voltage ranges.

It is recommended to set and measure the PL IO-bank supply-voltages before mounting of TE 4 x 5 module to avoid failures and damages to the functionality of the mounted SoM.


Power supply with minimum current capability of 3A for system startup is recommended.

Power Supply

Single power supply with minimum current capability of 3A at 5V for system startup is recommended.

Power Consumption

Power Consumption

Typical power consumption for TE0703-05 + TE0715-01 module with SD micro card inserted, Ethernet connected and link up, system booted into Linux prompt and idling is 5V / 0.55A.

Power-On Sequence

It is not allowed to feed any voltage to any external I/O pin before there is no power indication on M3.3VOUT pins. Presence of 3.3V on B2B JB2 connector pins 9 and 11 indicates that module is properly powered up and ready.

If any of the VCCIOA, VCCIOB, VCCIOC or VCCIOD will be powered through external connectors J1 or J2, then corresponding VCCIO jumper should also be removed.
