Part Description: MAX3349E DS

Part Details:

19-3952; Rev 0; 3/06 USB 2.0 Full-Speed Transceiver with UART Multiplexing Mode MAX3349E General Description Features The MAX3349E ±15kV ESD-protected, USB transceiver ±15kV ESD HBM Protection on D+ and D- provides a full-speed USB interface to a lower voltage UART Mode Routes External UART Signals to microprocessor or ASIC. The device supports enumer- D+/D- ation, suspend, and VBUS detection. A special UARTmultiplexing mode routes external UART signals (Rx Internal Linear Regulator Allows Direct Powering and Tx) to D+ and D-, allowing the use of a shared con- from the USB Cable nector to reduce cost and part count for mobile Separate Voltage Input for UART devices. Transmitter/Receiver (VUART) The UART interface allows mobile devices such as PDAs, cellular phones, and digital cameras to use either Internal 1.5k Pullup Resistor on D+ Controlled UART or USB signaling through the same connector. by Enumerate Input The MAX3349E features a separate UART voltage sup- Internal Series Termination Resistors on D+ and D- ply input to support legacy devices using +2.75V signal-ing. The MAX3349E supports a maximum UART baud Complies with USB Specification Revision 2.0, rate of 921kbaud. Full-Speed 12Mbps Operation Upon connection to a USB host, the MAX3349E enters Built-In Level Shifting Down to +1.4V, Ensuring USB mode and provides a full-speed USB 2.0 compliant Compatibility with Low-Voltage ASICs interface through VP, VM, RCV, and OE. The MAX3349E V features internal series termination resistors on D+ and BUS Detection D-, and an internal 1.5k pullup resistor to D+ to allow Combined VP and VM Inputs/Outputs the device to logically connect and disconnect from the No Power-Supply Sequencing Required USB while plugged in. A suspend mode is provided forlow-power operation. D+ and D- are protected from Available in 16-Bump UCSP (2mm x 2mm) electrostatic discharge (ESD) up to ±15kV. Package The MAX3349E is available in 16-pin TQFN (4mm x4mm) and 16-bump UCSPTM (2mm x 2mm) packages, Ordering Information and is specified over the -40°C to +85°C extended tem- PART PIN-PACKAGE PACKAGE CODE perature range.
