• This manual provides an overview of the distribution view of the pins in the GW1NRF series of Bluetooth FPGA products. The four I/O Banks that form the GW1NRF series of
• Bluetooth FPGA products are marked with four different colors.

Various symbols are used for the user I/O, power, and ground. The various symbols and colors used for the various pins are defined as follows:

• •      ” denotes the I/O in BANK0. The filling color changes with the BANK;
  •  denotes the I/O in BANK1. The filling color changes with the BANK;
  •   ” denotes the I/O in BANK2. The filling color changes with the BANK;
  •  ” ” denotes the I/O in BANK3. The filling color changes with the BANK;
  •  ”  ” denotes VCC, VCCX, and VCCO. The filling color does not change;
  •  ” ” denotes VSS, the filling color does not change;
  •  ” ” denotes NC;
•  “ ” denotes BLE, the filling color does not change
