V1.0		Full documentation	Kintex7 XC7K160T-2FFG676

The HiRADDA set is composed of two boards : HiRADDA Core and HiRADDA Mezzanine.

HiSADDA is compatible with the FPGA Rack Backplane for interconnecting different boards with the help of the HVME16 version of the HES-SO Backplane Bus and the HES-SO VME IP Core.

• 1x 100MHz quartz for boot clock
• 1x expansion connectors with the following FPGA banks :
  • Full bank 13 (with 24 diffs or 48 single-ended + 2 single-ended, total 50 pins / Voltage range : 1.14V to 3.465V).
  • Full bank 32 (with 24 diffs or 48 single-ended + 2 single-ended, total 50 pins / Voltage range : 1.14V to 1.89V).

• 1x JTAG connector
• 1x DIN41612 VME Compatible Connector 3x32 pins (full HVME32) with CMOS AC termination on all signal pins (default: unsoldered)

Mezzanine board

• 1x USB2 (micro USB connector, FTDI FT232HL)
• 1x power supply

Power supply considerations

The following power rails are produced on board :

• +A5.0V (ADS1675)
• +D1.0V (FPGA Core)
• +D1.8V (SSRAM I/Os + FPGA BANK)
• +D2.5V (SSRAM + FPGA BANK)
• +D3.0V (ADS1675 + FPGA BANK)
• +D3.3V (VME + FPGA BANK)

VME connector logic levels

The I/O bank which interfaces the VME connector is only 3.3V. Be careful with other FPGA Rack boards with 2.5V/3.3V jumper.

Programmation

This board can be programmed in 2 ways,

• First the FPGA can be directly programmed.
• Second the FPGA can be programmed via the onboard Flash memory (SPI x1/x4).

More explanation for FLASH programmation are available here.

Known issues

• None.
