  • Page 27: Maximum Power Budget

    Figure 8: Maximum Power Budget Estimation Power Sequencing The Mercury+ ST1 base board will only power up when a Mercury module is properly connected to its socket. As soon as the main voltage (VCC_MAIN) is applied, VCC_5V will start up and the mated Mercury module will drive up a 3.3 V supply (VCC_3V3_MOD).

  • Page 28: Power Enable/Power Good

    - please refer to the module’s user manual for details on power generation. On the Mercury+ ST1 base board the VCC_5V supply is always active and cannot be turned-off, except for when removing the 12 V power input on the board.

  • Page 29: Vcc_Io Source Pins Positions - Power Pins

    VCC_FMC_VIOB is a supply output from the FMC card. Only one source for each I/O voltage VCC_IO_A, VCC_IO_B or VCC_IO_C is allowed. The factory default jumper settings are 1-2, 7-8, 11-13. As a consequence of these settings, no voltage is applied to the Mercury module connector, therefore it prevents the module from booting. PWGD LED will not be lit.

  • Page 30: Jumper Settings Vcc_Io_B

    Warning! Use only VCC_IO_A, B and C voltages compliant with the equipped Mercury module; any other voltages may damage the equipped Mercury module, as well as other devices connected to Mercury+ ST1 base board.

    By default, the UART communication between the FTDI device and FPGA is active. The Xilinx JTAG mode can be activated using the Enclustra MCT [10] and is independent of the UART connection. The library used by the MCT is available free of charge; it allows users to integrate module enumeration, FPGA and SPI flash configuration, and I2C communication functionality in their own application.

  • Page 36: I2C Communication

    I2C Communication There are several I2C devices on the Mercury+ ST1 base board connected to two separate I2C buses. The Mercury module and the FTDI device can be I2C masters on the main I2C bus. An overview of the I2C structure is given in Table 27 and Figure 13.
