In order to support one PCB the two CY4 FPGAs EP4CGX150CF23C8N & EP4CGX30CF23C8N,
Need to connect additional I/O pins of EP4CGX30CF23C8N (see below) to GND/VCCINT (1.2V)
I compile EP4CGX150CF23C8N with Migration to EP4CGX30CF23C8N, as expected at the project.pin report the pins connected to GND/VCCINT for example:
my question is if I assembled EP4CGX30CF23C8N and pin H16 (for example) connected to VCCINT(1.2V) , is it ok or Should I add serial resistor to the VCCINT pins in order to disconnect it when I use the EP4CGX30CF23C8N?
Thanks & Best Regards,
Hello Israel Ben-Yeda,
For me, it is a good practice to add additional resistor to the I/O pins even if you are not using it as it is connected to VCCINT.
