The USB332x family of Hi-Speed USB 2.0 transceivers sets a new standard for integration by combining six functions into one extremely small size to help meet the tight board space and cost requirements of today's portable consumer electronics products. The highly integrated USB332x transceivers are designed in a wafer-level chip scale package (WLCSP) measuring 1.95mm x 1.95mm. One of the key features of the USB332x family is the ability to protect portable products from extreme over-voltage conditions of up to +30V on VBus. The need for external VBus over-voltage protection ICs, USB switches, electrostatic discharge (ESD) protection devices, and reference oscillators is eliminated, thereby minimizing eBOM part count and conserving valuable board space. The flexible and easy-to-use USB332x family also allows the USB connector to act as a single port of connection for high speed data transfer, battery charging and stereo/mono audio accessories.
