Controller Chip

Description

The idea behind the microcontroller unit is its role as a cost-effective and energy-efficient processor designed for specific applications. Over the past few years, some of these devices have significantly increased in capability, leading to a blurring of the traditional definition of a microcontroller. Nowadays, controller chips are integrated into various devices such as Metal Detectors, Wearables, SSDs and CPUs.
