ABSTRACT:
A dual-personality extended USB (EUSB) system supports both USB and EUSB memory cards using an extended 9-pin EUSB socket. Each EUSB memory card includes a PCBA having four standard USB metal contact pads disposed on an upper side of a PCB, and several extended purpose contact springs that extend through openings defined in the PCB. Passive components are mounted on a lower surface of the PCB using SMT methods, and IC dies are mounted using COB methods, and then the components and IC dies are covered by a plastic molded housing. The extended 9-pin EUSB socket includes standard USB contacts and extended use contacts that communicate with the PCBA through the standard USB metal contacts and the contact springs. The PCBA includes dual-personality electronics for USB and EUSB communications.
