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.
