P89LPC9351FDH,518 Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that can be used with the P89LPC9351FDH,518?
  The maximum clock frequency is 12 MHz, but it can be overclocked up to 18 MHz with some limitations.
• How do I configure the oscillator for the P89LPC9351FDH,518?
  The oscillator can be configured using the OSCCFG register. The oscillator frequency can be set to 12 MHz, 6 MHz, or 3 MHz, and the oscillator mode can be set to internal, external, or crystal oscillator mode.
• What is the maximum current consumption of the P89LPC9351FDH,518?
  The maximum current consumption is 12 mA at 12 MHz, but it can be reduced to 2 mA in idle mode and 0.5 mA in power-down mode.
• How do I use the UART interface on the P89LPC9351FDH,518?
  The UART interface can be used by configuring the UART registers (UART0, UART1, or UART2) and using the UART interrupts. The UART baud rate can be set using the UARTBSEL register.
• Can I use the P89LPC9351FDH,518 with a 5V power supply?
  No, the P89LPC9351FDH,518 is a 3.3V device and should not be used with a 5V power supply. Using a 5V power supply can damage the device.
