The MAX3349EA ±15kV ESD-protected, USB transceiv-
er provides a full-speed USB interface to a lower voltage
microprocessor or ASIC. The device supports enumera-
tion, 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 connec-
tor 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 sup-
ply input to support legacy devices using +2.75V signal-
ing. The MAX3349EA supports a maximum UART baud
rate of 921kbaud.
Upon connection to a USB host, the MAX3349EA enters
USB mode and provides a full-speed USB 2.0 compliant
interface through VP, VM, RCV, and OE. The
MAX3349EA 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 discon-
nect from the USB while plugged in. A suspend mode is
provided for low-power operation. D+ and D- are pro-
tected from electrostatic discharge (ESD) up to ±15kV.
The MAX3349EA 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.
