8542.31.00.15 - 8-bit

This HTS classification, 8542.31.00.15, specifically covers electronic integrated circuits that function as controllers, including microcontrollers, and are designed with an 8-bit architecture. These are fundamental processing units where data is handled in 8-bit chunks, making them suitable for a wide range of embedded systems and control applications requiring relatively simpler processing capabilities. Their design prioritizes cost-effectiveness and power efficiency for specific tasks.

The distinction from sibling categories lies in the bit architecture. While 8542.31.00.20 pertains to 16-bit controllers and 8542.31.00.25 to 32-bit controllers, this category is exclusively for those operating with 8-bit data pathways. The "Other" category, 8542.31.00.30, encompasses controllers that do not fall within the specified bit architectures.

As a leaf node within the HTS structure, this category does not have further subdivisions. Therefore, classification within 8542.31.00.15 is determined solely by the confirmation that the integrated circuit is a controller (or microcontroller) and operates on an 8-bit basis. Examples include microcontrollers used in simple appliances, basic automotive control modules, and low-power embedded devices.
