Pin application and brief schematic diagram
Common pin description: VCCINT: FPGA core power supply, requires precise 1.0V power supply. VCCIO: I/O voltage domain, usually 3.3V or 2.5V. TCK/TDI/TDO/TMS: Standard JTAG interface for downloading and debugging. Configuration pins (such as M0/M1/M2): Select the boot mode (such as SPI, JTAG, Slave Serial). GTPCLK: If an external high-speed clock input is used, a differential crystal oscillator needs to be connected to GTPCLKP/N. Bank partition: The voltage domain needs to be reasonably distinguished to avoid voltage mismatch across banks.
