Custom-defined SoC delivers 350K gates/mm²

What is an ASIC?
An application-specific integrated circuit (ASIC) is an IC that is customised for a specific application (end product or a closely related family of end products), such as a chip which is designed to run a cellular handset.

What is a microcontroller?
A microcontroller or MCU is a computer-on-a-chip. It is a type of microprocessor dedicated to execute one task (as opposed to general purpose microprocessor), embedded in another device to control the features of that device thus, the name 'embedded controller'.

What is a semiconductor?
A class of materials, for instance silicon and germanium, whose electrical properties lie between those of conductors (such as copper and aluminum) and insulators (such as glass and rubber). It displays relatively high resistance in pure state and much lower resistance when it contains small amounts of certain impurities.
