Key Pin Functions:

Here's a summary of major functional categories for the pins:

Power Supply Pins: These pins provide the necessary power to the device. Examples: VCC, VCCINT, VCCAUX, GND, etc. They are crucial for powering different sections of the FPGA (core voltage, auxiliary voltage, etc.). Input/Output (I/O) Pins: These are pins where signals are either input or output to/from the FPGA. Examples: IO pins like IO_L1N_T3, IO_L2P_T4, etc. I/O pins are used for interfacing with external components such as sensors, controllers, or other devices. Clock Pins: Special pins are dedicated to clock signals for synchronization. Examples: CLK1, CLK2, etc. These are used for providing a clock to the FPGA or for receiving a clock signal. Configuration Pins: Used for configuring the FPGA device during startup. Examples: M0, M1, TDI, TDO, etc. Control Pins: Pins like INIT, DONE, PROG_B, and RESET are used for controlling the FPGA's operation during the configuration process. Differential Pairs: Used for high-speed signal transmission, such as for high-frequency serial communication (e.g., PCIe, Ethernet). Example: TXP, TXN (transmit differential pair). Ground Pins: Ground pins are vital for providing a common reference for voltage levels and for minimizing noise in the system. Example: GND, VSS. Auxiliary Pins: These are often used for additional features like JTAG, UART, etc. Example: TMS, TDI, TDO.
