Overview
The Trenz Electronic TE0714 is an industrial-grade SoM (System on Module) based on Xilinx Artix-7, 16 MByte Flash memory and powerful switching mode power supplies for all on-board voltages. A large number of configurable I/O's is provided via rugged high-speed stacking strips. TE0714 is the smallest module with transceiver (3 x 4 cm).

Control Signals
- Overview of Boot Mode, Reset, Enables,
|
Boot process is controlled by signals on the board to board (B2B) connector.
Signal | Direction | Signal State | Description |
---|
BOOTMODE
| input | high or open | Master SPI, x4 Mode
| low or ground
| Slave SelectMAP | PROG_B | input | pulsed low | Clear FPGA configuration (falling edge) and initiate a new configuration sequenz (next rising edge). | DONE | output | high | Completion of configuration sequence. |
|
SPI FPGA pins D02 and D03 have no pull-ups on the module, so with PUDC=High option, those pins are floating if there are no pull-ups on baseboard. As those pins have SPI RESET function when Quad mode is not enabled, it is mandatory to either add pull-ups on user baseboard or program the Quad Enable bit in Flash nonvolatile status register. |
Signals, Interfaces and Pins
Notes : - For modules which needs carrier us only classes and refer to B2B connector if more than one is used, for example
|
JTAG Interface
JTAG access to the Xilinx Artix-7 FPGA device is provided through connector JM1.

On-board Peripherals
Notes : - add subsection for every component which is important for design, for example:
- Ethernet PHY
- USB PHY
- Programmable Clock Generator
- Oscillators
- eMMCs
- RTC
- FTDI
- ...
- DIP-Switches
- Buttons
- LEDs

Quad SPI Flash
On-board SPI flash memory S25FL127S (U7) is used to store initial FPGA configuration. Besides FPGA configuration, remaining free flash memory can be used for user application storage. All four SPI data lines are connected to the FPGA allowing x1, x2 or x4 data bus widths. Maximum data rate depends on the bus width and clock frequency used.
SPI Flash QE (Quad Enable) bit must be set to high or FPGA is unable to load its configuration from flash. By default this bit is set to high at the manufacturing plant. |
Power and Power-On Sequence
To power-up a module, power supply with minimum current capability of 1A is recommended.
TE0714 needs one single power supply with nominal of 3.3V.
Power Consumption
Test Condition (25 °C ambient) | VIN Current mA | Notes |
---|
TE0714-35, TEBT0714, empty design, GT not enabled | 110mA |
|
|
Actual power consumption depends on the FPGA design and ambient temperature.
Power Distribution Dependencies
Power-On Sequence
There is no specific or special power-on sequence, single power source is needed as VIN, rest of the sequence is automatic.

Physical Dimensions
Module size: 40 mm × 30 mm. Please download the assembly diagram for exact numbers.
Mating height with standard connectors: 8 mm
PCB thickness: 1.6 mm
Highest part on PCB: approximately 2.5 mm. Please download the step model for exact numbers.
All dimensions are shown in mm. Additional sketches, drawings and schematics can be found here.
Variants Currently In Production
On REV 01 JM2 Pin 54 was connected to GND. When R27 is not populated, REV 02 is backwards compatible to REV 01. When R27 is set, check your baseboard to not connect this pin to GND. For all new baseboards JM2.54 should be used as VCCIO output (it will then be 1.8V or 3.3V depending the voltage settings on the module. |
