Specialized ICs

1. Overview

Specialized ICs (Application-Specific Integrated Circuits, ASICs) are customized microchips designed for specific functions or applications, unlike general-purpose ICs. They optimize performance, power efficiency, and size for targeted tasks, playing a critical role in modern electronics such as telecommunications, automotive systems, and AI accelerators.

2. Main Types and Functional Classification

ASIC (Application-Specific IC)	Custom-designed for a specific application with fixed functionality	Smartphones, IoT devices, medical imaging equipment
FPGA (Field-Programmable Gate Array)	Reconfigurable logic blocks and interconnects for dynamic functionality	5G base stations, industrial automation, prototyping systems
SoC (System-on-Chip)	Integrates CPU, GPU, memory, and peripherals on a single chip	Wearable devices, autonomous vehicles, edge computing
ASSP (Application-Specific Standard Product)	Standardized ICs for specific applications (not fully customized)	Networking switches, display drivers, power management
PLD (Programmable Logic Device)	Basic programmable ICs for simple logic operations	Consumer electronics, automotive sensors
