Selection Guide

Choose the XC7K420T-2FFG1156I when you need the highest performance (-2 speed grade) and industrial temperature range (-40°C to +100°C) in a 1156-FCBGA package. This is ideal for aerospace, defense, and outdoor applications. If your design operates only in commercial environments (0°C to +85°C), the XC7K420T-2FFG1156C offers identical logic resources at a lower cost. For designs that do not require maximum clock speed, the XC7K420T-1FFG1156C provides a more economical option. If power consumption is a primary concern and performance can be sacrificed, the XC7K420T-L2FFG1156I low-power variant is suitable.

Key Differentiators

  • Industrial temperature range (vs XC7K420T-2FFG1156C)
  • Higher speed grade (vs XC7K420T-1FFG1156C)
  • Standard power vs low-power (vs XC7K420T-L2FFG1156I)

Design Notes

The XC7K420T-2FFG1156I requires a robust power delivery network for its 1.0V core supply. Use multiple low-ESR ceramic capacitors (0.1uF and 1uF) placed close to the VCCINT pins, and a bulk capacitor (10uF) per power pin group. The VCCAUX supply (1.8V) also needs adequate decoupling. Refer to the AMD Kintex-7 power management application note for detailed recommendations.

With a 1156-FCBGA package and industrial temperature range, thermal management is critical. The device can dissipate significant power at high utilization. Use a heatsink or active cooling for designs exceeding 10W dissipation. Ensure adequate airflow and consider the thermal resistance of the PCB. The junction temperature must not exceed 100°C for reliable operation.

For high-speed signals, maintain controlled impedance traces (50 ohm single-ended, 100 ohm differential) and minimize via stubs. The FC-BGA package requires a multi-layer PCB with dedicated power and ground planes. Follow AMD's PCB design guidelines for the FFG1156 package to ensure signal integrity and manufacturability.
