Table 3: JTAG interface connector.

JTAGEN pin on B2B connector JM1 is used to control which physical device is accessible via JTAG interface. If this pin is set to low or left open, JTAG interface is enabled for Xilinx Artix-7 FPGA, if set to high, JTAG interface for System Controller CPLD will be enabled.

The use of Xilinx legacy development tools (ISE, iMPACT) is not recommended. iMPACT does not recognize any Xilinx Artix-7 below A100T model.

System Controller I/O Pins

Special purpose pins are connected to the System Controller CPLD which have following default function:

On-board LEDs

There are three LEDs available on TE0710-02 SoM. Two are status LEDs, and one can be freely used by user design. The user LED is routed to the FPGA as 'USERLED'.

When the FPGA is not configured the status LEDs will flash continuously. Once the FPGA configuration has completed, the status LEDs can be used by the user FPGA design.

On-board Peripherals

32 MByte Quad SPI Flash Memory

An SPI flash memory S25FL256S (U7) is provided for FPGA configuration file storage. After configuration completes the remaining free memory can be used for application data 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 selected 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 during power-on. By default this bit is set to high at the manufacturing plant.

System Controller CPLD

System Controller CPLD (Lattice MachXO2-256HC, U4) is used to control FPGA configuration process. The FPGA is held in reset (by driving the PROG_B signal low) until all power supplies have stabilized.

By driving signal RESIN to low you can reset the FPGA. This signal can be driven from the user’s baseboard PCB via the B2B connector JM2 pin 18.

Input EN1 is also gated to FPGA reset, should be open or pulled up for normal operation. By driving EN1 low, on-board DC-DC converters are not turned off.

User can create their own System Controller design using Lattice Diamond software. Once created it can be programmed into CPLD via JTAG interface.

DDR3 SDRAM

The TE0710-02 SoM has one 512 MByte volatile DDR3 SDRAM IC (U12) for storing user code and data.

  • Part number: MEM4G08D3EABG-125 (Memphis) 
  • Supply voltage: 1.5V
  • Organization:  64M words x 8 bits x 8 banks
  • Memory speed limited by Xilinx Artix-7 speed grade and MIG

Configuration of the DDR3 memory controller in the FPGA should be done using the MIG tool in the Xilinx Vivado Design Suite IP catalog.

Ethernet PHYs

The TE0710-02 is equipped with two Texas Instruments TLK106 10/100 Mbit Ethernet PHYs (U3 and U6). The I/O voltage is fixed at 3.3V. The reference clock input for both PHYs is supplied by on-board 25 MHz oscillator (U9). Both Ethernet PHYs are connected to FPGA bank 14 using MII interface.

Note: Pin ETH2_INT (power down or interrupt, default function is power down) is connected to FPGA bank 16 (pin D10).

MAC Address EEPROM

TE0710-02 module is equipped with 2 Kbit serial Electrically Erasable PROM (EEPROM, U14).  It provides pre-programmed 48-bit Extended Unique Identifier (EUI-48™) to identify network hardware MAC address which is write-protected to ensure tamper-proof designs. This EEPROM can be accessed by UNI/O® serial interface bus using Manchester encoding techniques. The clock and data are combined into a single, serial bit stream (SCIO), where the clock signal is extracted by the receiver to correctly decode the timing and value of each bit. The bus is controlled by a master device (Xilinx Artix-7) which determines the clock period, controls the bus access and initiates all operations, while the EEPROM works as a slave. Refer to Microchip's 11AA02E48 datasheet for more information.

Power and Power-On Sequence

Power Supply

Power supply with minimum current capability of 2A for system startup is recommended.

 Power Input PinVoltage RangeCurrent
VIN3.3V to 5.5VTypical 200mA, depends on customer design and setup.
3.3VIN3.3VTypical 50mA, depends on customer design and setup.

Table 7: Typical power consumption during normal operation.

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

Lowest power consumption is achieved when powering the module from single 3.3V power supply. When using split 3.3V/5V supplies the power consumption (and heat dissipation) will rise, this is due to the DC-DC converter efficiency (it decreases when VIN/VOUT ratio rises).

Power-On Sequence

For highest efficiency of on-board DC-DC regulators, it is recommended to use same 3.3V power source for both VIN and 3.3VIN power rails. Although VIN and 3.3VIN can be powered up in any order, it is recommended to power them up simultaneously.

It is important that all baseboard I/Os are 3-stated at power-on until System Controller sets PGOOD signal high (B2B connector JM1, pin 30), or 3.3V is present on B2B connector JM2 pins 10,12 or 91, meaning that all on-module voltages have become stable and module is properly powered up.

See Xilinx datasheet DS181 (for Artix7) for additional information. User should also check related baseboard documentation when choosing baseboard design for TE0710-02 module.

A 3.3V supply is also needed and must be supplied from the user's PCB. An output 3.3V supply is available on some of the board connector pins (see section 'Power Rails'). The input 3.3VIN will be switched to the internal 3.3V voltage level after the FPGA 1.0V supply is stable. Than 3.3V supply will be available on the B2B connector pins.

The regulators can be powered from the 3.3V supply or a 5V supply if preferred. The options for powering the board are as follows:

  • Apply 5V to pins VIN and 3.3V to pins 3.3VIN on the board connector
  • Apply 3.3V to pins VIN and 3.3VIN on the board connectors.

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.
