4.6 Programming
The PolarFire device is programmed using the on-board FlashPro5 programmer. For more information
about programming the PolarFire device, see
Appendix: Programming PolarFire FPGA Using the On-
Board FlashPro5, page 35 and UG0714: PolarFire FPGA Programming User Guide .
For more information, see the Board-Level Schematics document (provided separately).
4.6.1 FTDI
The key features of the FT4232H chip are:
• USB 2.0 high-speed (480 Mbps) to UART/MPSSE IC
• Single-chip USB-to-quad serial ports in various configurations
• Entire USB protocol handled on the chip without requiring USB-specific firmware programming
• USB 2.0 high-speed (480 Mbps) and full-speed (12 Mbps) compatibility
• Two multi-protocol synchronous serial engines (MPSSE) on channel A and channel B to simplify
synchronous serial protocol (USB to JTAG, I2C, SPI, or bit-bang) design
• FTDI chip requires 1.8 V chip core voltage and +3.3 V I/O voltage
