SC16C554DBIB64,128 Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the SC16C554DBIB64,128 can operate at?
  The maximum clock frequency of the SC16C554DBIB64,128 is 16 MHz, but it can also operate at lower frequencies down to 300 kHz.
• How do I configure the UART for 9-bit data transmission?
  To configure the UART for 9-bit data transmission, set the MCR register to enable 9-bit mode, and then set the word length to 9 bits using the LCR register. Additionally, ensure that the parity and stop bit settings are correctly configured.
• Can I use the SC16C554DBIB64,128 as a UART replacement in an existing design?
  Yes, the SC16C554DBIB64,128 is a drop-in replacement for many existing UARTs, including the 16C554 and 16C654. However, ensure that the pinout and register settings are compatible with your existing design.
• How do I handle FIFO overflow and underflow conditions?
  To handle FIFO overflow and underflow conditions, enable the FIFO interrupt and set the interrupt threshold to a suitable value. The device will generate an interrupt when the FIFO reaches the threshold, allowing you to take corrective action.
• What is the maximum baud rate that the SC16C554DBIB64,128 can support?
  The maximum baud rate that the SC16C554DBIB64,128 can support is 1.5 Mbps, but this may vary depending on the clock frequency and system configuration.
