NUC230LD2AE - Nuvoton

NUC230LD2AE Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for the NUC230LD2AE?
  The NUC230LD2AE can operate from -40°C to 105°C, but the recommended operating temperature range is -20°C to 85°C for optimal performance and reliability.
• How do I configure the clock source for the NUC230LD2AE?
  The NUC230LD2AE has an internal oscillator and can also use an external clock source. To configure the clock source, you need to set the CKS (Clock Source Select) bits in the Clock Control Register (CLK_CFG). Refer to the datasheet for the specific register settings.
• What is the maximum current consumption of the NUC230LD2AE?
  The maximum current consumption of the NUC230LD2AE depends on the operating frequency and voltage. At 3.3V and 24MHz, the typical current consumption is around 15mA. However, this can increase to around 30mA at 48MHz. Refer to the datasheet for more detailed information on power consumption.
• How do I implement a watchdog timer on the NUC230LD2AE?
  The NUC230LD2AE has a built-in watchdog timer that can be enabled by setting the WDTEN (Watchdog Timer Enable) bit in the Watchdog Timer Control Register (WDT_CFG). You can also set the watchdog timer period and timeout using the WDT_PR (Watchdog Timer Period) and WDT_TO (Watchdog Timer Timeout) registers.
• Can I use the NUC230LD2AE with an external crystal oscillator?
  Yes, the NUC230LD2AE can be used with an external crystal oscillator. You need to connect the crystal oscillator to the XT1 and XT2 pins and configure the clock source to use the external oscillator. Refer to the datasheet for more information on the recommended crystal oscillator specifications.
