FAQ

What is the maximum operating frequency of the XC6SLX100-3CSG484C?

The XC6SLX100-3CSG484C has a -3 speed grade, guaranteeing timing closure up to 500 MHz for internal logic paths and 1,080 Mbps for differential I/O (LVDS). Actual achievable frequency depends on design placement, routing, and clock network usage - verified via static timing analysis in Vivado or ISE tools. The XC6SLX100-3CSG484C supports DCM and PLL outputs up to 500 MHz with jitter specifications defined in DS162.

Does the XC6SLX100-3CSG484C support configuration via SPI flash?

Yes, the XC6SLX100-3CSG484C supports Master SPI configuration mode, allowing direct boot from standard quad-SPI or standard SPI flash devices. Configuration bitstream is loaded automatically on power-up when M[2:0] pins are set to 001. The XC6SLX100-3CSG484C also supports fallback and multi-bitstream selection using address lines and mode pins.

Can the XC6SLX100-3CSG484C interface directly with DDR2 SDRAM?

Yes, the XC6SLX100-3CSG484C supports DDR2 SDRAM interfaces through its multi-standard I/O banks and dedicated DQS routing. It meets JEDEC DDR2-800 timing requirements when used with proper PCB layout, termination, and calibration. The XC6SLX100-3CSG484C includes hardware support for write leveling and read-leveling calibration sequences in ISE design tools.

What thermal considerations apply to the XC6SLX100-3CSG484C in continuous operation?

The XC6SLX100-3CSG484C uses a thermally enhanced CSG package with an exposed pad requiring solder connection to a PCB thermal plane. Junction-to-board thermal resistance (θ_JB) is 12.5°C/W. For full utilization at 85°C ambient, a 2-layer thermal pad and ≥4 thermal vias per corner are recommended. The XC6SLX100-3CSG484C thermal profile is documented in Xilinx UG382 and DS162.
