3.1. Guidelines: VCCIO Range Considerations

There are several VCCIO range considerations because of I/O pin configuration function and I/O bank location.
  • Banks 1 and 8 have I/O pins with configuration function. The configuration function of these pins support only 1.5 V to 3.3 V. If you want to access the configuration function of these pins during user mode (run time), for example JTAG pins, the VCCIO of the pin's bank is limited to a range of 1.5 V to 3.3 V. If you want to use I/O standards with 1.2 V to 1.35 V in bank 1 or 8 during user mode, do not use the configuration function of the bank's I/O pins.
  • For devices with banks 1A and 1B:
    • If you use the VREF pin or the ADC, you must supply a common VCCIO voltage to banks 1A and 1B.
    • If you do not use the VREF pin or the ADC, you can supply separate VCCIO voltages to banks 1A and 1B.
  • If you plan to migrate from devices that has banks 1A and 1B to devices that has only bank 1, ensure that the VCCIO of bank 1A and 1B are the same.
  • For the V36 package of the 10M02 device, the VCCIO of these groups of I/O banks must be the same:
    • Group 1—banks 1, 2 and 8
    • Group 2—banks 3, 5, and 6
  • For the V81 package of the 10M08 device, the VCCIO of these groups of I/O banks must be the same:
    • Group 1—banks 1A, 1B, and 2
    • Group 2—banks 5 and 6
