µPD720114 is a compact and environment-friendly USB 2.0 hub controller. With a 2.5V regulator for the core logic, USB terminating resistors, and other resistors provided on-chip, µPD720114 greatly reduces the number of external components required. Power-saving technology has been introduced to reduce the power consumption significantly, both during operation and in stand-by. Supporting up to four downstream ports, each with an LED port status indicator, the µPD720114 hub controller is best suited for USB hub boxes, PC monitors and port replicators.
