The Trenz Electronic TE0728 is a SoC module integrating a Xilinx Automotive Zynq-7020, 512 MByte DDR3 SDRAM with 16-Bit width, 16 MByte Flash Memory for configuration and operation, two 100 Megabit Ethernet transceivers, and powerful switch-mode power supplies for all on-board voltages. A large number of configurable I/O's is provided via rugged high-speed stacking strips.

All this in a compact 6 x 6 cm form factor, at the most competitive price.

All parts are at least automotive temperature range up to +105°C. The module operating temperature range depends on customer design and cooling solution. Please contact us for options.

Recommended Peripheral mapping for MIO Voltage bank 0.


There is no fixed mapping for PS7 UART, if needed it can be mapped to free pins from MIO1 Bank or via EMIO to PL pins.

Recommended mapping for primary (console, debug) UART are MIO52, MIO53 for all cases when MIO1 is not used for off-board Gigabit ETH PHY.

PL Peripherals

Both Ethernet PHY IC's are connected to PL pins in Bank 34, all PHY IC pins are connected to FPGA pins, there is no sharing of signals for the two PHY's.

PUDC pin is connected with pull-up to 3.3V those pre-configuration pull-ups are disabled by default. Strapping resistor exist to change the PUDC mode.

XADC Usage

XADC PinConnected toNotes

XADC is used with internal reference option.

Note the XADC capable pins are not routed differentially to the B2B connector. The performance and usability of the XADC must be evaluated.


There are two 100 MBit Extreme Temperature Ethernet PHY's DP83848YB on the board. Datasheet is available from TI, Literature number SNLS208H. Both PHY's are connected with all I/O Pins to FPGA Bank 34 (VCCIO = 3.3V). PHY Clock 25 MHz source is provided from MEMS Oscillator. All LED outputs have on-board pull-ups. Outputs to Magnetics have also required termination resistors on board.

Both PHY's must be operated in MII Mode, other modes are not supported. It is possible to use PS ENET0 or ENET1 via EMIO routing or Ethernet IP Cores implemented in PL Fabric.

Magnetics center tap voltage
POWERDOWN/INTL21R20on-chipIt is recommended to configure FPGA I/O as input with Pullup or as output driving 1 if Interrupt not used.
RESET_NM15R16on-chipIt is recommended to configure FPGA I/O as input with Pullup or as output (active low PHY Reset).

It is recommended to add IOB TRUE constraint for the MII Interface pins.

When connecting the PHY's to Zynq PS ETH0, ETH1 EMIO GMII Interfaces it is recommended to use GMII to MII Wrap IP Core. This IP core maps the EMIO GMII to external MII Interface.

By the 13 August 2005, Member States shall have ensured that systems are set up allowing final holders and distributors to return waste electrical and electronic equipment at least free of charge. Member States shall ensure the availability and accessibility of the necessary collection facilities. Separate collection is the precondition to ensure specific treatment and recycling of waste electrical and electronic equipment and is necessary to achieve the chosen level of protection of human health and the environment in the European Union. Consumers have to actively contribute to the success of such collection and the return of waste electrical and electronic equipment. Presence of hazardous substances in electrical and electronic equipment results in potential effects on the environment and human health.
