Generalizing, we can say that, in CPLDs, there are a few hundred function blocks or logic blocks , typically less than a thousand in number, which are accessible by a single big interconnect.

While the exact FPGA architecture is not publicly released by manufacturers, we can still get higher level architecture, which will help in understanding FPGAs and its working. Copyright: Xilinx Inc. In short, FPGAs are massive! Specialized hardware on FPGA. When an FPGA is powered up, the device is always blank. There certainly are exceptions to this.

Some manufacturers have come up with FPGAs that have built-in configuration flash. Otherwise, for most other applications FPGAs are generally preferred. So, depending on the application you might need to use both in a particular design. So, there you go! We hope that you are now more enlightened about CPLDs vs FPGAs and can make an informed decision on which one to use depending on your application needs.
