What Is an SoC? A Basic Definition

[harlan4096]

SoC stands for system on a chip. This is a chip/integrated circuit that holds many components of a computer—usually the CPU (via a microprocessor or microcontroller), memory, input/output (I/O) ports and secondary storage—on a single substrate, such as silicon. Having all of these components on one substrate means SoCs use less power and take up less space than their multi-chip counterparts. SoCs are becoming increasingly popular with the growth of Internet of Things and edge and mobile computing. Take, for example, Intel’s September 2018 acquisition of SoC firm Silicon Engineering Group and older acquisitions of Altera and others.

One common example of tech that uses an SoC is video game consoles, such as the Nvidia Tegra X1 used in the Nintendo Switch or the AMD Flute and AMD Gonzalo SoCs expected to power the next Xbox and PlayStation, respectively. Raspberry Pi computers, Arduino boards and STEM kits also use SoCs. SoCs are often used in STEM kits because they are easy to use, and, therefore, helpful in teaching STEM. You also find SoCs in smartphones and tablets.
