Embedded systems have come a long way over the years, unlocking a wide range of features, functionalities and performance never before seen. One type of embedded development that has become increasingly common is the usage of CPLDs (Complex Programmable Logic Devices). The M5-512/256-6SAC is an example of such a device, and in this article we’ll look at this device’s application field and working principle.

What is a CPLD?

A CPLD (Complex Programmable Logic Device) is a specialized form of hardware designed to perform specific tasks with very high speed. They are typically used in microcontroller-based systems and generally require less chip area than a microcontroller. A CPLD can be programmed with different functions and performs a given task way faster than a microcontroller.
