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).
Refer to http://trenz.org/te0714-info for the current online version of this manual and other available documentation.

Clocking
Clock | Default Frequency | IC | FPGA | Notes |
---|---|---|---|---|
CLK25MHz | 25 MHz | U8 | T14 | Frequency depends on the module variant. Output is compatible to 3.3V and 1.8V I/O standard of the FPGA bank. |
MGT_CLK | 125MHz | U2 | B6/B5 | Frequency depends on the module variant |
Boot Process
Boot mode is controlled by the MODE signal on the board to board (B2B) connector:
MODE signal State | Boot Mode |
---|---|
high or open | Master SPI, x4 Mode |
low or ground | Slave SelectMAP |
Note |
---|
SPI D2 and D3 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. |
On-board Peripherals
16 MByte 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.
Note |
---|
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.
Power Supply
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-On Sequence
There is no specific or special power-on sequence, single power source is needed as VIN, rest of the sequence is automatic.
Bank Voltages
Bank | Voltage | Notes |
---|---|---|
0 Config and B14 | 1.8V or 3.3V | Depends on module variant |
15 | User | Supplied from baseboard via B2B connector, max 3.3V |
34 | User | Supplied from baseboard via B2B connector, max 3.3V |

Note |
---|
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. |
