Changing VCCIO voltage during device operation (Cyclone)

865 Views

Hello,

Is it possible to regulate the VCCIO voltage in order to achieve different voltage standards during FPGA (Cyclone I) operation?

And the second question: Can I turn off VCCIO in some IO banks, then reconfigure the device and power VCCIO again on these banks? (VCCINT and VCCIO of configuration pins will be supplied permanently)
