Cyclone IV E(EP4CE30) FPGA JTAG and USB-Blaster

Hi Team, I am working with a Cyclone IV E FPGA(EP4CE30), where all my banks (Bank 1–8) have VCCIO = 3.3V. The FPGA core voltage is 1.2V, and the PLL supply is 2.5V. I am configuring the FPGA in Pass...

Hi, thanks for the quick support.

I assume we will follow the same approach for the configuration pins as well. I am planning to configure the Cyclone IV E FPGA in Passive Serial (PS) mode using:

  • Single-Device PS Configuration Using an External Host (as shown in Figure 8–13)
  • PS Configuration Using a Download Cable (as shown in Figure 8–17)

I believe the pull-up resistor should be connected to VCCA (2.5 V). If you have any concerns or suggestions regarding this, please share your thoughts.

i have attached my draft schematic for your reference.
