Ultra-low-voltage processors (ULV processors) are a class of microprocessor that are deliberately underclocked to consume less power (typically 17 W or below), at the expense of performance.

These processors are commonly used in subnotebooks, netbooks, ultraportables and embedded devices, where low heat dissipation and long battery life are required.^[1]
