General Description

The MAX14830 evaluation kit (EV kit) provides a proven

design to evaluate the MAX14830 quad-channel univer-

sal asynchronous receiver-transmitter (UART) IC. Each

UART contains 128 words of receive and transmit first-in/

first-out (FIFO) buffer that can be controlled through the

SPI or I

C interface. Each of the four UARTs are selected

through SPI or I

C in-band addressing.

Each of the four UARTs can interface with an IO-Link

master transceiver or an RS-485/RS-232 multiprotocol

transceiver. The EV kit contains on-board IO-Link master

transceivers, RS-485/RS-232 multiprotocol transceivers,

and double-pole/double-throw (DPDT) switches are used to

select between the IO link and RS-485/RS-232 transceivers.

The EV kit operates from a +3.3V and a +24V DC supply

and requires 100mA of current from each supply. This

EV kit requires a user-supplied SPI/I

C controller and

software.

The EV kit comes with a MAX14830ETM+ installed.
