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.

On-board Peripherals
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.

Board to Board Connectors
These connectors are hermaphroditic. Odd pin numbers on the module are connected to even pin numbers on the baseboard and vice versa.
3 x 4 modules use two Samtec Razor Beam LSHM connectors on the bottom side.
- 2 x REF-189016-02 (compatible to LSHM-150-04.0-L-DV-A-S-K-TR), (100 pins, "50" per row).
When using the same type on baseboard, the mating height is 8mm. Other mating heights are possible by using connectors with a different height.
Order number | Connector on baseboard | compatible to | Mating height |
---|---|---|---|
23836 | REF-189016-01 | LSHM-150-02.5-L-DV-A-S-K-TR | 6.5 mm |
LSHM-150-03.0-L-DV-A-S-K-TR | LSHM-150-03.0-L-DV-A-S-K-TR | 7.0 mm | |
23838 | REF-189016-02 | LSHM-150-04.0-L-DV-A-S-K-TR | 8.0 mm |
LSHM-150-06.0-L-DV-A-S-K-TR | LSHM-150-06.0-L-DV-A-S-K-TR | 10.0mm |
The module can be manufactured using other connectors upon request.

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.
