MAX14830

Quad Serial UART with 128-Word FIFOs

General Description

Features

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 I C controller interface. A PLL and fractional

baud-rate generators allow a high degree of flexibility in

baud-rate programming and reference clock selection.

S SPI Up to 26MHz Clock Rate

S Fast-Mode Plus (Fm+) I C Interface Up to 1MHz

S 128-Word Transmit and Receive FIFOs Per UART

S 6Mbaud (max) Data Rate in 16x Sampling Mode

S 12/24Mbaud (max) Data Rate in 2x/4x Rate Modes

S Fractional Baud-Rate Generators, Predivider, and

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

Phase-Locked Loop (PLL)

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.

S Transmitter Synchronization Through SPI

Commands

S Four Timers Routed to GPIOs

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.

S Automatic Hardware Flow Control Using RTS_

and CTS_ Outputs and Inputs

S Automatic Software Flow Control (XON/XOFF)

S Auto Transceiver Direction Control

S Programmable Setup and Hold Times for

The 128-word FIFOs have advanced FIFO control reduc-

ing host processor data flow management.

S Auto Transmitter Disable

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.
