LC4256V-75FTN256AC Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VCCIO first, followed by VCCINT, and then VREF. This ensures that the internal voltage regulators are powered up correctly.
  • To implement a reliable JTAG chain, ensure that each device has a unique TDI/TDO pin connection, and use a JTAG cable with a 1-kΩ resistor in series with the TCK signal to prevent signal reflection.
  • The maximum frequency for the LC4256V-75FTN256AC's PLL is 400 MHz. However, the actual frequency limit may vary depending on the specific application and board design.
  • No, the LC4256V-75FTN256AC is not designed for radiation-hardened applications. It is intended for commercial use only. For radiation-hardened applications, consider using a different device specifically designed for such environments.
  • To optimize power consumption, use the device's power-saving features, such as the sleep mode, and optimize the clock frequency and voltage settings for your specific application. Additionally, consider using a power-efficient I/O standard and minimizing the number of active I/Os.
