LPC1311FHN33,551 Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the LPC1311FHN33?
  The recommended operating voltage range for the LPC1311FHN33 is 2.0 V to 3.6 V, with a typical voltage of 3.3 V.
• How do I configure the clock settings for the LPC1311FHN33?
  The clock settings for the LPC1311FHN33 can be configured using the Clock Generation Unit (CGU) registers. The CGU provides a flexible clock generation system that allows the user to select the clock source, divider, and multiplier to generate the desired clock frequency.
• What is the maximum frequency of the LPC1311FHN33?
  The maximum frequency of the LPC1311FHN33 is 72 MHz, which is achieved by using the internal PLL clock source.
• How do I use the UART interface on the LPC1311FHN33?
  The UART interface on the LPC1311FHN33 can be used by configuring the UART registers, such as the UART Control Register (UARTCR) and the UART Baud Rate Register (UARTBRD). The UART interface supports various baud rates, data bits, and stop bits, and can be used for asynchronous communication.
• What is the purpose of the Brown-Out Detection (BOD) feature on the LPC1311FHN33?
  The Brown-Out Detection (BOD) feature on the LPC1311FHN33 is used to detect when the voltage supply drops below a certain threshold, and can be used to reset the device or generate an interrupt to alert the system of a potential power failure.
