Quad Serial UART with 128-Word FIFOs

MAX14830

EVALUATION KIT AVAILABLE

19-5547; Rev 3; 1/13

General Description

The MAX14830 is an advanced quad universal asyn-

chronous receiver-transmitter (UART), each UART hav-

ing 128 words of receive and transmit first-in/first-out

(FIFO) and a high-speed serial peripheral interface

(SPIK) or I2C controller interface. A PLL and fractional

baud-rate generators allow a high degree of flexibility in

baud-rate programming and reference clock selection.

Each of the four UARTs is selected by in-band SPI/I2C

addressing. Logic-level translation on the transceiver

and controller interfaces allows ease of interfacing to

microcontrollers, FPGAs, and transceivers that are pow-

ered by differing supply voltages.

Extensive features simplify transceiver control in half-

duplex communication applications. The MAX14830

features the ability to synchronize the start of individual

UART’s transmission by SPI-based triggering. On-board

timers allow programming of delays between transmit-

ters as well as clock generation on GPIOs.

The 128-word FIFOs have advanced FIFO control reduc-

ing host processor data flow management.

The MAX14830 is available in a 48-pin TQFN (7mm x

7mm) package and is specified to operate over the

extended -40NC to +85NC temperature range.
