SoC

System-on-Chip

A System-on-Chip (SoC) is a highly integrated circuit that combines multiple electronic components of an entire system onto a single chip. These typically include processors, memory, input/output interfaces, communication units, and often even analog components.

SoCs are optimized for specific applications and are used in various industries, including consumer electronics, automotive, medical technology, and telecommunications. They provide a cost-efficient and space-saving solution for modern, compact systems such as smartphones, wearables, and IoT devices.

Features and Advantages:
