TIs TL16C550C is a Single UART with 16-Byte FIFOs and Auto Flow Control. A high-speed 16550 UART 9-pin serial port transfers data at up to 920 Kbps baud rate, ensuring that connected hardware runs at peak performance. My small test bench is modified to work with 32-bit mode.

. . Report abuse. Frank Diersch, Digital Factory Division, Siemens AG. 5M Baud (Baud is of bits transmittedsec, incl uding start, stop, data and parity). When the Mini UART is enabled the SoC frequency will by default be locked so shouldn&x27;t change or cause baud rate changes. 5V Tolerant Inputs.

UART is self-timed each individual bit occupies a specific amount of time based on the configured baud rate, e.
