Why CPLD better than FPGA?

For below some reason, CPLD is better than FPGA:

  • CPLD is an integrated circuit that helps to implement digital systems while FPGA is an integrated circuit designed to be configured by a customer or a designer after manufacturing.
  • CPLD is cost-effective while the FPGA is expensive than CPLDs.
  • The logic resource is also a major difference between CPLD and FPGA. CPLD provides minimum logic resources while FPGA provides a massive amount of logic resources and storage elements to create complex systems.
  • Power consumption is also different between CPLD and FPGA, CPLD consumes low power while FPGA consumes more power.
  • CPLD is made up of larger blocks while FPGA is made up of tiny logic blocks.
  • CPLD and FPGA is their memory. CPLD uses EEPROM while FPGA uses RAM.
  • Besides it is easier to predict the delay in CPLD than in FPGA.
  • CPLD is more secure than FPGA because it has built-in nonvolatile memory.
  • CPLD is suitable for small to medium scale applications whereas FPGA is suitable for complex applications.
