8542.31.00.70 - System on chip (SoCs)

This HTS category, 8542.31.00.70, specifically covers "System on Chip (SoCs)". SoCs are integrated circuits that combine multiple components, such as processors, memory, graphics processors, and I/O controllers, onto a single chip. They are designed to perform a wide range of functions within a single electronic device, embodying a complete system within a single package. This comprehensive integration is their defining characteristic.

SoCs are distinct from sibling categories that classify more specialized integrated circuits. While sibling categories might cover standalone processors (microprocessors), controllers (microcontrollers), or programmable logic devices, SoCs integrate these functionalities and often many more into a single unit. The key differentiator is the multi-functional, system-level integration present in SoCs, whereas siblings represent individual functional blocks or more generalized programmable circuits.

As this node is a leaf node within the HTS structure, there are no further subcategories. Classification into 8542.31.00.70 depends on the integrated nature of the semiconductor device, wherein a single chip houses a central processing unit, memory, and other functional units required to operate as a self-contained system. This is in contrast to assemblies of multiple separate integrated circuits that might perform similar functions but are not integrated onto a single piece of semiconductor material.
