JTAG Interface

JTAG access to the Xilinx Artix-7 and to the System Controller CPLD is provided through B2B connector JM2.

Table 3: Pin mapping of JTAG Interface on B2B connector

JTAGSEL 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 smaller System Controller CPLD and have following default configuration:

Pin NameModeFunctionDefault ConfigurationB2B Connector
STAT_SC2OutputPower GoodActive high when all on-module power supplies are working properly.JM1-30

On-board LEDs

The TE0711 SoM has total of 4 on-board LED's. LED's D1, D2 and D3 are connected to the Xilinx Artix-7 FPGA and can be freely used by user design. LED D4 is the System Controller CPLD status LED.

Clocking

The TE0711-01 is equipped with MEMS oscillator (SiT8008AI-73-XXS-100.000000E, U8) to provide 100 MHz clock signal for Xilinx Artix-7 FPGA pin P17.

On-board Peripherals

32 MByte Quad SPI Flash Memory

On-board SPI flash memory S25FL256S (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.

System Controller CPLD

The system controller is used to coordinate the configuration of the FPGA. The FPGA is held in reset (by driving the PROG_B signal) until the power supplies have sequenced. Low level at NRST_SC0 pin also resets the FPGA. This signal can be driven from the user’s PCB via the B2B connector pin JM2-18. Input EN_SC3 is also gated to FPGA Reset and should be open or pulled up for normal operation. EN_SC3 low turns off on board DC-DC converters and stops power-on sequencing.

It is possible for the user to create their own system controller design using the Lattice Diamond software. Once created the design can be programmed into the device using the JTAG pins. The signal JTAGSEL should be set to 3.3V to enable programming mode. For normal operation it should be set to 0V.

There are one status LED connected to the system controller CPLD. When the FPGA is not configured the LED will flash continuously. Finally once FPGA configuration has completed the LEDs can be used in the user's FPGA design.

Dual channel USB to UART/FIFO

The TE0711-01 SoM has on-board high-speed USB 2.0 to UART/FIFO FT2232H controller from FTDI. Channel A can only be used in simple UART mode. Channel B can be used as UART in FT245 FIFO mode, JTAG (MPSSE) mode or in high-speed serial modes.

FT2232H controller is connected to the FPGA bank 14 with fixed 3.3V VCCIO and all signalling must meet the LVCMOS 3.3V I/O standard.

256 Byte EEPROM is connected to the FT2232H-chip to store custom configuration settings. These settings can be changed using FTDI provided tools that can be downloaded from FTDI website.

Power and Power-On Sequence

Power Supply

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

 Power Input PinVoltage RangeMax Current
VIN3.3V to 5.5VTypical 200mA, depending on customer design and connections.
3.3VIN3.3VTypical 50mA, depending on customer design and connections.

Table 6: Typical power consumption.

VIN and VIN3.3V can be connected to the same power source (3.3V).

Lowest power consumption is achieved when powering the module from single 3.3V 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/O's are 3-stated at power-on until System Controller sets STAT_SC2 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 Artix-7 datasheet DS181 for additional information. Also check related baseboard documentation when choosing baseboard design for TE0711-01 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 has stabilized. 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.

4 x 5 modules use two or three 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)
  • 1 x REF-189017-02 (compatible to LSHM-130-04.0-L-DV-A-S-K-TR), (60 pins, "30" per row) (depending on module)
