ASIC: what it means.
Application-specific design allows a circuit to be organized for its intended job. An ASIC may target a processing, communications or control function. This specialization differs from configuring a general-purpose processor through software alone. (Arm: ASIC definition)
An FPGA permits configuration of its logic and routing after fabrication. An ASIC’s manufactured circuit is not reconfigured in that same way. This does not justify assuming that every ASIC lacks registers, settings or embedded software; examine the actual design. (Arm: ASIC definition)
Put the definition to work.
The abbreviation describes a chip’s intended role. It does not, by itself, tell you its package, supply voltage, interfaces, or whether it can be substituted for another device. (Hybrid Electronics glossary)
Questions to ask next.
Use these questions as a reading checklist, not as a device-selection recommendation. Exact manufacturer documentation takes priority over a general definition.
- Required function and customization
- Development versus production needs
- Documented programmability and interfaces

Common ASIC questions.
Is an ASIC always the best choice?
No universal choice follows from the label. Use the required function, design flexibility, development effort, production volume and documented operating behavior to compare implementations. (Arm: ASIC definition)
