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 enumer-
ation, 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 con-
nector 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 MAX3349E features a separate UART voltage sup-
ply input to support legacy devices using +2.75V signal-
ing. 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 1.5k pullup resistor to D+ to allow
the device to logically connect and disconnect from the
USB while plugged in. A suspend mode is provided for
low-power operation. D+ and D- are protected from
electrostatic discharge (ESD) up to ±15kV.
The MAX3349E is available in 16-pin TQFN (4mm x
4mm) and 16-bump UCSP (2mm x 2mm) packages,
and is specified over the -40°C to +85°C extended tem-
perature range.
