●The MAX14830ETM+ is a quad serial UART with 128 word FIFOs in 48 pin TQFN package. This advanced UART has 128 words of receive and transmit 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. Logic level translation on transceiver & controller interfaces allows ease of interfacing to microcontrollers, FPGAs and transceivers that are powered by differing supply voltages. Extensive features simplify transceiver control in half-duplex communication applications. IC features ability to synchronize start of individual UART"s transmission by SPI based triggering. On-board timers allow programming of delays between transmitters and clock generation on GPIOs. The 128 word FIFOs have advanced FIFO control reducing host processor data flow management. It is used in PLC, IO-link master controllers & point of sales systems.
