Currently, the ASIC in the integrated circuit industry is considered to be an integrated circuit designed for a specific purpose. Refers to integrated circuits designed and manufactured to meet the needs of specific users and the needs of specific electronic systems. The ASIC is characterized by the needs of specific users. ASICs have the advantages of smaller size, lower power consumption, higher reliability, improved performance, enhanced confidentiality, and lower cost compared with general-purpose integrated circuits in mass production.

Application Specific Integrated Circuits (ASICs) are custom-made for specific applications and are not intended for general use (IC). For example, a chip designed to operate in a digital recorder or a high efficiency bitcoin excavator is an ASIC. Dedicated Standard Products (ASSP) are between ASICs and industry standard integrated circuits such as the 7400 family or the 4000 family.

As feature sizes shrink and design tools continue to improve over the years, the biggest complexity (and functionality) in ASICs has increased from 5,000 logic gates to over 1 billion. Modern ASICs typically include the entire microprocessor, memory block, including large building blocks such as ROM, RAM, EEPROM, and flash memory. This type of ASIC is often referred to as an SoC (system on a chip). Designers of digital ASICs typically use a hardware description language (HDL) such as Verilog or VHDL to describe the functionality of the ASIC.

Field programmable gate arrayFPGAIs a modern technology for building breadboards or prototypes from standard components; programmable logic blocks and programmable interconnects allow the same FP to be used in many different applicationsGA. For smaller designs or lower throughput, FPGAs may be more cost effective than ASIC designs, even in production. ASIC's non-recurring engineering (NRE) costs can reach millions of dollars. As a result, device manufacturers typically prefer FPGAs for prototyping and devices with low throughput and ASICs for very large throughput, where NRE costs can be amortized over many devices.
