Boot Modes

TE0729 supports primary boot from

  • JTAG
  • SPI Flash
  • SD Card

Boot from on-board eMMC is also supported as secondary boot (FSBL must be loaded from SPI Flash).

The boot modes are controlled by the Pins 'BOOT1' and 'BOOT2' on the board to board (B2B) connector. Pins routed through the CPLD by default firmware with pull-up, if not connected on B2B.

On-board Peripherals

Gigabit Ethernet

The TE0729 is equipped with a Marvell Alaska 88E1512 Gigabit Ethernet PHY (U3) connected to PS Ethernet GEM0 (referenced in this manual Ethernet0). The I/O Voltage is fixed at 1.8V. The reference clock input of the PHY is supplied from an on board 25MHz oscillator (U10).

Ethernet0 PHY connection:

LED0-pin J2-57 on B2B connector
LED1-pin J2-59 on B2B connector
CONFIG-Connected to GND, PHY Address 0

The TE0729 SoM is also equipped with two additional Microchip KSZ8081MLXCA Ethernet PHY's (IC's U17 and U19) to provide further 10/100 Mbps Ethernet interfaces with the identifiers Ethernet1 and Ethernet2. The reference clock input of both PHYs is supplied from the same 25MHz oscillator (U10), which also provides Ethernet0 Gigabit PHY with a reference clock signal.

Ethernet1 PHY connection to B2B-connectors:

ETH1_LED0J2-34Status LED
ETH1_LED1J2-32Transmission LED

Ethernet2 PHY connection to B2B-connectors:

ETH2_LED0J2-16Status LED
ETH2_LED1J2-14Transmission LED

All other pins of the PHYs are connected to Bank34 of Zynq, see schematic for further details.

USB Interface

Microchip USB3320 is connected via ULPI interface to the Zynq PS USB0. I/O voltage level is fixed at 1.8V and PHY reference clock input is supplied from the on-board 52.000000 MHz oscillator (U12).

The schematic for the USB connector and required components is different depending on the USB usage. USB standard A or B connectors can be used for Host or Device modes. A Mini USB connector can be used for USB Device mode. A USB Micro connector can be used for Device mode, OTG Mode or Host Mode.

RTC - Real Time Clock

An Intersil temperature compensated real time clock IC ISL12020MIRZ is used for timekeeping (U22). Battery voltage must be supplied to the module from the main board.

Battery backed registers are accessed at I2C slave address 0x57. General purpose RAM is accessed at I2C slave address 0x6F. This RTC IC is supported by the Linux OS, so it can be used as hwclock device.


TE0729 module has three Microchip 24AA025E48 EEPROMs (U8, U9 and U20) which contain globally unique EUI-48TM compatible 48-bit node (MAC) addresses. These EEPROMs are organized as two blocks of 128 x 8-bit memory. One of the blocks stores the 48-bit node address and is write protected, the other block is available for application use. EEPROMs are accessible using I2C slave address 0x50 for MAC-Address1 (U8), 0x51 for MAC-Address2 (U9)0x52 for MAC-Address3 (U20).


TE0729 has support for hardware watchdog function. By default the watchdog is disabled at power up. Please contact Trenz Electronic for details how to enable watchdog function.

Power and Power-On Sequence

For startup, a power supply with minimum current capability of 3A is recommended.

VIN and 3.3VIN can be connected to the same source (3.3 V).

Power-up sequence at start-up

The Trenz TE0729 is equipped with several DC-DC-voltage-regulators to generate the required on-board voltages with the values 1V (FPGA core), 1.8 V (VCC0 MIO, VCCAUX, AVCC, VCCPLL, VDD USB and ETH PHYs), 1.5V (DDR3), 2.5V (Industrial fast ETH-PHYs) and 3.3V (VCCIO, peripheral components).

In the first step at device start-up the voltages 1V and 1.8V are generated for the FPGA core and programmable logic banks. The voltages 1.5V and 2.5 V are enabled after the voltage 1V has stabilized. The voltage 3.3V is enabled by the CPLD system controller at last.

The voltage 3.3V is available on B2B-connector at pins J1-65, J1-66 and an indicator for stabilized on-board voltages in steady state.

To avoid any damage to the SoM, check the 3.3V voltage before powering up the SoC's I/O bank voltages VCCIO_13 and VCCIO_33.
Pay attention to the voltage level of the I/O-signals, which must not be higher than VCCIO + 0.4V.

Board to Board Connectors

The TE0729 module has two 120-pin double-row REF-189019-02 connectors on the bottom side which are compatible with Samtec BSE-060-01-L-D-A connectors. Mating connectors on the baseboard are REF-189019-01, which are compatible with Samtec BTE-060-01-L-D-A connectors.
