MC13892DJVL Frequently Asked Questions (FAQs)

• What is the recommended operating temperature range for the MC13892DJVL?
  The recommended operating temperature range for the MC13892DJVL is -40°C to 85°C, although it can tolerate storage temperatures from -55°C to 150°C.
• How do I configure the MC13892DJVL for low-power mode?
  To configure the MC13892DJVL for low-power mode, set the PWDNB pin high and ensure the VDDIO supply is within the recommended range. Additionally, reduce the clock frequency and disable unnecessary peripherals to minimize power consumption.
• What is the maximum clock frequency supported by the MC13892DJVL?
  The MC13892DJVL supports a maximum clock frequency of 32 kHz, although it can be configured to operate at lower frequencies for power-saving purposes.
• How do I interface the MC13892DJVL with an external crystal oscillator?
  To interface the MC13892DJVL with an external crystal oscillator, connect the crystal between the XTAL_IN and XTAL_OUT pins, and ensure the crystal frequency is within the recommended range of 32 kHz to 40 kHz.
• What is the purpose of the VDDIO pin on the MC13892DJVL?
  The VDDIO pin on the MC13892DJVL is used to power the I/O interfaces, such as the SPI and UART peripherals. It should be connected to a separate power supply or a voltage regulator to ensure proper operation.
