Part Details:

19-0667; Rev 0; 10/06 USB 2.0 Full-Speed Transceiver with UART Multiplexing Mode MAX3349EA General Description Features The MAX3349EA ±15kV ESD-protected, USB transceiv- ±15kV ESD HBM Protection on D+ and D- er provides a full-speed USB interface to a lower voltage UART Mode Routes External UART Signals to microprocessor or ASIC. The device supports enumera- D+/D- tion, suspend, and VBUS detection. A special UARTmultiplexing mode routes external UART signals (Rx and Internal Linear Regulator Allows Direct Powering Tx) to D+ and D-, allowing the use of a shared connec- from the USB Cable tor to reduce cost and part count for mobile devices. Separate Voltage Input for UART The UART interface allows mobile devices such as Transmitter/Receiver (VUART) PDAs, cellular phones, and digital cameras to use eitherUART or USB signaling through the same connector. Internal 1.5k Pullup Resistor on D+ Controlled The MAX3349EA features a separate UART voltage sup- by Enumerate Input ply input to support legacy devices using +2.75V signal- Internal Series Termination Resistors on D+ and D- ing. The MAX3349EA supports a maximum UART baudrate of 921kbaud. Complies with USB Specification Revision 2.0, Full-Speed 12Mbps Operation Upon connection to a USB host, the MAX3349EA entersUSB mode and provides a full-speed USB 2.0 compliant Built-In Level Shifting Down to +1.4V, Ensuring interface through VP, VM, RCV, and OE. The Compatibility with Low-Voltage ASICs MAX3349EA features internal series termination resistors V on D+ and D-, and an internal 1.5k pullup resistor to BUS Detection D+ to allow the device to logically connect and discon- Combined VP and VM Inputs/Outputs nect from the USB while plugged in. A suspend mode is No Power-Supply Sequencing Required provided for low-power operation. D+ and D- are pro-tected from electrostatic discharge (ESD) up to ±15kV. Available in 16-Bump UCSP (2mm x 2mm) The MAX3349EA is available in 16-pin TQFN (4mm x Package 4mm) and 16-bump UCSPTM (2mm x 2mm) packages, Ordering Information and is specified over the -40°C to +85°C extended tem-perature range.
