MAX3349E Datasheet Usb 2.0 Full Speed Transceiver

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: .. 19-3952; Rev 0; 3/06 USB 2.0 Full-Speed Transceiver with UART Multiplexing.

General Description

The MAX3349E ±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.

Key Features

  • a separate UART voltage supply input to support legacy devices using +2.75V signaling. The MAX3349E supports a maximum UART baud rate of 921kbaud. Upon connection to a USB host, the MAX3349E enters USB mode and provides a full-speed USB 2.0 compliant interface through VP, VM, RCV, and OE. The MAX3349E features internal series termination resistors on D+ and D-, and an internal 1.5kΩ pullup resistor to D+ to allow the device to logically connect and disconnect from the USB while plugged in.
