SC16IS741IPW,118 datasheet by NXP Semiconductors

SC16IS741IPW,118 Frequently Asked Questions (FAQs)

• What is the maximum baud rate supported by SC16IS741IPW,118?
  The SC16IS741IPW,118 supports baud rates up to 5 Mbps, but it's recommended to limit it to 1 Mbps for reliable operation.
• How do I configure the UART interface for 9-bit data transmission?
  To configure the UART interface for 9-bit data transmission, set the MCR[7] bit to '1' and the LCR[2] bit to '1'. This enables 9-bit data transmission with a 9th bit as a parity bit.
• What is the purpose of the XOFF and XON characters in the SC16IS741IPW,118?
  The XOFF (Transmit Off) and XON (Transmit On) characters are used for software flow control. When the receiver's buffer is full, it sends an XOFF character to the transmitter to pause transmission. When the buffer has space available, it sends an XON character to resume transmission.
• How do I reset the SC16IS741IPW,118?
  The SC16IS741IPW,118 can be reset by asserting the RST pin low for at least 10 ns. This resets the device to its default state, clearing all registers and disabling the UART.
• What is the difference between the SC16IS741IPW,118 and the SC16IS750IPW,118?
  The main difference is that the SC16IS741IPW,118 has a single UART channel, while the SC16IS750IPW,118 has two UART channels. Both devices share similar features and pinouts, but the SC16IS750IPW,118 provides additional UART capabilities.
