Black USB Chip (UDP/COB) Product Guide

The phrase "black USB chip" primarily refers to UDP (USB Disk in Package) or COB (Chip-on-Board) technology. Unlike traditional USB drives that use a green PCB with separate components, these are monolithic, epoxy-encased black modules that integrate NAND flash, a controller, and oscillators into a single compact unit.
