SC16C654BIB64,157 datasheet by NXP Semiconductors

SC16C654BIB64,157 Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that can be used with this UART?
  The maximum clock frequency for the SC16C654BIB64,157 is 64 MHz. However, the actual clock frequency used may be limited by the specific application and system design.
• How do I configure the UART for 9-bit data transmission?
  To configure the UART for 9-bit data transmission, set the MCR (Modem Control Register) to enable 9-bit mode, and then set the LCR (Line Control Register) to select the 9-bit data length. Additionally, ensure that the transmitter and receiver are properly configured to handle the 9-bit data format.
• What is the maximum baud rate supported by this UART?
  The SC16C654BIB64,157 supports baud rates up to 3.125 Mbps. However, the actual maximum baud rate may be limited by the system design, clock frequency, and other factors.
• How do I handle FIFO overflow and underflow conditions?
  To handle FIFO overflow and underflow conditions, implement a FIFO management strategy that includes monitoring the FIFO status registers, using interrupts to detect overflow and underflow conditions, and implementing flow control mechanisms to prevent data loss.
• Can I use this UART in a multi-drop configuration?
  Yes, the SC16C654BIB64,157 can be used in a multi-drop configuration. However, ensure that the UART is properly configured to handle the multi-drop mode, and that the system design includes proper addressing and data routing mechanisms.
