ICE40HX8K-CT256 - Lattice Semiconductor

ICE40HX8K-CT256 Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that can be achieved with this FPGA?
  The maximum clock frequency of the ICE40HX8K-CT256 is dependent on the specific design and implementation. However, Lattice Semiconductor recommends a maximum clock frequency of 200 MHz for most applications.
• How do I implement a DDR3 memory interface with this FPGA?
  The ICE40HX8K-CT256 does not have a built-in DDR3 memory interface. However, you can implement a DDR3 memory interface using the FPGA's general-purpose I/O pins and a DDR3 memory controller IP core. Lattice Semiconductor provides a DDR3 memory controller IP core that can be used with this FPGA.
• What is the power consumption of this FPGA?
  The power consumption of the ICE40HX8K-CT256 depends on the specific design and implementation. However, according to the datasheet, the typical static power consumption is around 50 mW, and the dynamic power consumption is around 100 mW/MHz.
• Can I use this FPGA for high-speed serial interfaces like PCIe or SATA?
  The ICE40HX8K-CT256 is not suitable for high-speed serial interfaces like PCIe or SATA due to its limited transceiver bandwidth. The FPGA's transceivers are limited to 1.25 Gbps, which is not sufficient for high-speed serial interfaces.
• What is the maximum number of user I/Os available on this FPGA?
  The ICE40HX8K-CT256 has a total of 256 user I/Os, which can be used for various interfaces and applications.
