System on Chip (SoC) technology has revolutionized the field of microcontrollers, bringing enhanced functionality and integration. But what exactly is an SoC in a microcontroller, and how does it benefit embedded systems? This guide provides a detailed look at the role of SoC in microcontrollers.
What is a Microcontroller?
A microcontroller is a compact integrated circuit designed to govern a specific operation in an embedded system. It typically includes a CPU, memory, and I/O peripherals on a single chip, making it ideal for controlling small, dedicated devices.
What is SoC in a Microcontroller?
An SoC in a microcontroller takes integration a step further by incorporating additional components and functionalities into a single chip. This includes not only the CPU, memory, and I/O peripherals but also other features like connectivity modules, sensors, and power management units.
