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 (SPIK) or I2C controller interface.
The MAX14830 quad serial UART provides four independent UART channels, each with 128‑word transmit and receive FIFOs. It supports high‑speed SPI or I²C controller interfaces, fractional baud‑rate generators, and on‑board timers for flexible timing and GPIO clock generation.
The device is offered in a 48‑pin TQFN package, operates from –40 °C to +85 °C, and includes features such as automatic hardware flow control, transmitter synchronization, and logic‑level translation for easy integration with microcontrollers and FPGAs.
