MAX14830ETM+

MAX14830ETM+ 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. It is used in applications such as industrial control systems, programmable logic controllers (PLC), IO-link host controllers, medical systems, point-of-sales systems, airplane communication buses.

• SIR- and MIR-compliant IrDA encoder/decoder, line noise indication ensures data link integrity
• 128-word transmit and receive FIFOs per UART, transmitter synchronization through SPI commands
• Automatic software flow control (XON/XOFF), auto transceiver direction control
• Programmable setup and hold times for transceiver control, auto transmitter disable
• Special character detection, GPIO-based character detection, four timers routed to GPIO
• High-resolution programmable baud-rate, SPI upto 26MHz clock rate
• Fractional baud-rate generators, predivider, and phase-locked loop (PLL)
• Logic supply voltage range from 1.65V to 1.95V
• VA supply current is 400µA maximum at (VA = +2.35V to +3.6V, VL = +1.71V to +3.6V)
• Operating temperature range from -40°C to +85°C, 48-lead TQFN-EP package
