Its logic function cannot be changed to anything else because its digital circuitry is made up of permanently connected gates and flip-flops on silicon. It is meant to function as a CPU for its whole life. For example, CPU in your phone is an ASIC. They contain only one functionality in them and through the lifetime of the chip, it can perform only that function. It is a device that is created for a specific purpose or functionality. They are ASIC (Application Specific Integrated Circuits), FPGA (Field Programmable Gate Array) and SoC (System On Chip)ĪSIC means Application Specific Integrated Circuit. We have 3 types of IC’s based on the application.

Integrated Circuit: An integrated circuit or monolithic integrated circuit (also referred to as an IC, a chip, or a microchip) is a set of electronic circuits on one small flat piece (or “chip”) of semiconductor material that is normally silicon. So, if the length of the gate channel is 10nm we call it as 10nm technology node. The technology node depends on the length of the gate channel. This has been continuously driving the VLSI industry and the results of this law are the latest technological nodes (i.e. Moore’s Law: Moore’s law is the observation that the number of transistors in a dense integrated circuit doubles about every two years. Before starting the discussion on what is ASIC and what is FPGA, we will first learn about the basics that a VLSI enthusiast should know.
