Maxim MAX14830 Quad Serial UART Datasheet
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.
