Features

  • Non-volatile configuration memory. Unlike many FPGAs, an external configuration ROM is not required, and the CPLD can function immediately on system start-up.
  • For many legacy CPLD devices, routing constrains most logic blocks to have input and output signals connected to external pins, reducing opportunities for internal state storage and deeply layered logic. This is usually not a factor for larger CPLDs and newer CPLD product families.
