MAX14830ETM+T

MAX14830ETM+T is an advanced quad universal asynchronous receiver-transmitter (UART), each UART having 128 words of receive and transmit first-in/first-out (FIFO) and a high-speed serial peripheral interface (SPI) 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. 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 transmitters as well as clock generation on GPIOs. Applications include industrial control systems, programmable logic controllers (PLC), IO-link controllers, medical systems, point-of-sales systems, and airplane communication buses.
