19-6127 Rev 1 7/12 MAX14830 Evaluation Kit Evaluates: MAX14830 General Description Features The MAX14830 evaluation kit (EV kit) provides a proven S +3.3V and +24V Power-Supply Operation design to evaluate the MAX14830 quad-channel univer- S On-Board IO-Link Master Transceivers sal asynchronous receiver-transmitter (UART) IC. Each (MAX14824) UART contains 128 words of receive and transmit first-in/ S On-Board RS-485/RS-232 Multiprotocol first-out (FIFO) buffer that can be controlled through the 2 Transceivers (MAX3160E) SPI or I C interface. Each of the four UARTs are selected 2 through SPI or I C in-band addressing. S PCB Header for User-Supplied SPI- and 2 M I C-Compatible Signals Each of the four UARTs can interface with an IO-Link master transceiver or an RS-485/RS-232 multiprotocol S PCB Headers for UART Signals (J1) transceiver. The EV kit contains on-board IO-Link master S Evaluates the MAX14830 in a 48-Pin TQFN transceivers, RS-485/RS-232 multiprotocol transceivers, (7mm x 7mm) Package and double-pole/double-throw (DPDT) switches are used to select between the IO link and RS-485/RS-232 transceivers. S RoHS Compliant The EV kit operates from a +3.3V and a +24V DC supply S Proven PCB Layout and requires 100mA of current from each supply. This S Fully Assembled and Tested 2 EV kit requires a user-supplied SPI/I C controller and software. Ordering Information appears at end of data sheet. The EV kit comes with a MAX14830ETM+ installed.
