Differences MCU (Microcontroller Unit) and MPU (Microprocessor Unit) are two different types of embedded processors, and there are several key differences between them: 1. Purpose 👉MCU: MCUs are typically used in embedded systems that need to perform specific control tasks such as sensor data acquisition, automatic control, and control of embedded devices. They focus on … Read more
FPGA stands for Field-Programmable Gate Array, which is a type of programmable logic device. 1. Comparison with Microcontrollers Different Structures: 1.1 The number of pins, resources, and internal multipliers in a microcontroller is fixed, meaning its hardware is predetermined. Its functions can be achieved through software programming. 1.2 In contrast, the internal circuitry of an … Read more
