The maximum frequency of the clock input (SCL) for I2C mode is 400 kHz, but it can be up to 1 MHz in Fast-mode Plus.
The UART baud rate can be configured using the Baud Rate Register (UART_BAUD). The register value is calculated based on the desired baud rate and the input clock frequency.
The maximum data transfer rate for the UART is 5 Mbps.
Yes, the SC16IS752IPW can be used as a UART-to-I2C bridge. It can convert UART data to I2C and vice versa.
The SC16IS752IPW supports RTS/CTS flow control in UART mode. The RTS and CTS pins can be used to control the data flow between the transmitter and receiver.
