LC4256ZE-5TN100C Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VCCIO before VCC. This ensures that the I/O banks are powered up after the core voltage is stable.
  • To implement a CDC, use a synchronizer circuit or a FIFO-based CDC. The datasheet provides guidelines for CDC implementation, but a detailed design guide is available in the Lattice Semiconductor Corporation's application notes.
  • The maximum frequency of the LC4256ZE-5TN100C is 150 MHz. However, the actual frequency depends on the specific design, clock tree, and operating conditions.
  • To optimize for low power consumption, use the Power Estimator tool provided by Lattice Semiconductor Corporation. Additionally, implement power-saving techniques such as clock gating, voltage scaling, and dynamic voltage and frequency scaling.
  • The main difference is the speed grade. The LC4256ZE-5TN100C has a maximum frequency of 150 MHz, while the LC4256ZE-7TN100C has a maximum frequency of 200 MHz. The -7 speed grade is faster and more power-hungry than the -5 speed grade.
