MAX14830 Datasheet PDF - Maxim Integrated

Description

●The MAX14830 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.

●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 powered 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 transmitters as well as clock generation on GPIOs.

●The 128-word FIFOs have advanced FIFO control reducing host processor data flow management.

●The MAX14830 is available in a 48-pin TQFN (7mm × 7mm) package and is specified to operate over the extended -40°C to +85°C temperature range.
