SC16IS750IBS datasheet by NXP Semiconductors

SC16IS750IBS Frequently Asked Questions (FAQs)

• What is the maximum frequency of the clock input (SCL) for I2C mode?
  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.
• How do I handle the flow control in UART mode?
  The SC16IS750IBS has built-in flow control using RTS and CTS signals. The RTS signal is used to control the flow of data from the transmitter, and the CTS signal is used to control the flow of data to the receiver.
• What is the maximum baud rate supported by the SC16IS750IBS?
  The SC16IS750IBS supports baud rates up to 5 Mbps in UART mode.
• Can I use the SC16IS750IBS as a UART-to-I2C bridge?
  Yes, the SC16IS750IBS can be used as a UART-to-I2C bridge. It can convert UART data to I2C and vice versa.
• How do I configure the SC16IS750IBS for I2C mode?
  To configure the SC16IS750IBS for I2C mode, you need to set the M1 and M0 bits in the LCR register to '11'. You also need to set the I2C slave address using the I2AS register.
