MC14LC5480DW datasheet by Freescale Semiconductor

MC14LC5480DW Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the MC14LC5480DW?
  The recommended operating voltage range for the MC14LC5480DW is 2.7V to 5.5V, although it can operate down to 2.3V with reduced performance.
• How do I handle the power-on reset (POR) and brown-out reset (BOR) in my design?
  The MC14LC5480DW has an internal POR and BOR circuitry. To handle these, ensure a stable power supply, add a capacitor to the VCC pin, and consider using an external reset circuit if necessary.
• What is the maximum clock frequency supported by the MC14LC5480DW?
  The maximum clock frequency supported by the MC14LC5480DW is 20 MHz, although it can operate at lower frequencies with reduced power consumption.
• How do I configure the I/O pins for input or output?
  The I/O pins of the MC14LC5480DW can be configured as input or output using the Data Direction Register (DDR). Set the corresponding bit in the DDR to 0 for input or 1 for output.
• What is the purpose of the internal oscillator and how do I use it?
  The internal oscillator is a 1.2 MHz RC oscillator that can be used as a clock source. To use it, set the OSCCTL register to enable the internal oscillator and configure the clock prescaler as needed.
