Microchips are compact electronic devices built around integrated circuits, which combine miniature components on a semiconductor substrate. Depending on their design, they can control operations, process signals, or store information in larger electronic systems. The category includes named chip models such as the ATtiny13 and CL88020, alongside examples described as small or embedded chips. It also covers human implant microchips, a distinct type that commonly uses a passive transponder to communicate an identifying code when scanned; unlike a general-purpose processor, it does not independently perform complex computing. Together, these subjects show how microchip technology appears both in electronic components and in specialized implantable identification devices.
