0 Full-Speed Transceiver with UART Multiplexing Mode General Description The MAX3349EA ±15kV ESD-protected, USB transceiver provides a full-speed USB interface to a lower voltage microprocessor or ASIC.
The device supports enumeration, suspend, and VBUS detection.
A special UART multiplexing mode routes external UART signals (Rx and Tx) to D+ and D-, allowing the use of a shared connector to reduce cost and part count for mobile devices.
The UART interface allows mobile devices such as PDAs, cellular phones, and digital cameras to use either UART or USB signaling through the same connector.
The MAX3349EA features a separate UART voltage suppl...
