The MAX3107 is an advanced universal asynchronous

receiver-transmitter (UART) with 128 words each of

receive and transmit first-in/first-out (FIFO) that can be

controlled through I

4x rate modes allow a maximum of 24Mbps data rates.

A phase-locked loop (PLL), prescaler, and fractional

baud-rate generator allow for high-resolution baud-rate

programming and minimize the dependency of baud

rate on reference clock frequency.

Autosleep and shutdown modes help reduce power

consumption during periods of inactivity. A low 640µA

(typ) supply current and tiny 24-pin TQFN (3.5mm x

3.5mm) package make the MAX3107 ideal for low-power

portable devices.

Integrated logic-level translation on the controller and

transceiver (RX/TX and RTS/CTS) interfaces enable use

with a wide selection of RS-232/RS-485 transceivers.

Automatic hardware and software flow control with

selectable FIFO interrupt triggering offloads low-level

activity from the host controller. Automatic half-duplex

transceiver control with programmable setup and hold

times allow the MAX3107 to be used in high-speed appli-

cations, for example Profibus-DP.

The MAX3107 is ideal for use in portable devices,

industrial applications, and automotive applications. The

MAX3107 is available in a 24-pin SSOP package and a

24-pin TQFN package. It is specified over the -40NC to

+85NC extended ambient temperature range.
