TC646VOA Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for the TC646VOA is 2.7V to 5.5V, although it can operate down to 2.5V with reduced performance.
  • To ensure the internal oscillator's stability and accuracy, it's recommended to use a 0.1uF to 1uF capacitor between the VDD and VSS pins, and to keep the oscillator pins (OSC1 and OSC2) away from noise sources and high-frequency signals.
  • The TC646VOA's I/O pins can source or sink up to 25mA of current, but it's recommended to limit the current to 10mA or less to ensure reliable operation and prevent overheating.
  • The BOD can be configured by setting the BODEN bit in the Configuration Register (CONFIG). It's recommended to set the BOD voltage threshold to around 2.5V to ensure the device resets properly during power-on or brown-out conditions.
  • The VREF pin is an internal voltage reference output that can be used as a reference voltage for analog-to-digital converters (ADCs) or digital-to-analog converters (DACs). It's recommended to buffer the VREF output with an external op-amp to prevent loading and ensure accuracy.
