7.5. Device Configuration Pins

Configuration Pins Summary

The following table lists the Cyclone® V configuration pins and their power supply.

Note:
  1. he TDI, TMS, TCK, and TDO pins are powered by VCCPD of the bank in which the pin resides.
  2. The CLKUSR, DEV_OE , DEV_CLRn , and DATA[15..5] pins are powered by VCCPGM during configuration and by VCCIO of the bank in which the pin resides if you use it as a user I/O pin.
  3. The DCLK, AS_DATA0, AS_DATA1, AS_DATA2, AS_DATA3, and nCSO pins have 25 kOhm pull-up resistors when the MSEL pins are set to AS configuration scheme.
