FPGA Configuration Modes

TrionĀ®, Topaz, and Titanium FPGAs have dedicated configuration pins. You select the configuration mode by setting the appropriate condition on the input configuration pins. TrionĀ®, Topaz, and Titanium FPGAs support the following configuration modes.

Table 1. FPGA Configuration Modes
Mode Description
SPI Active (serial/parallel) The FPGA loads the bitstream itself from non-volatile SPI flash memory.
SPI Passive (serial/parallel) An external microprocessor or microcontroller sends the bitstream to the FPGA using the SPI interface.
JTAG A host computer sends instructions through a download cable to the FPGA's JTAG interface using JTAG instructions.
