ATTINY461A-SU Frequently Asked Questions (FAQs)

  • The ATTINY461A-SU can operate from -40°C to +125°C, but the recommended operating temperature range is -40°C to +85°C for optimal performance.
  • The ATTINY461A-SU can use an internal RC oscillator, an external crystal oscillator, or an external clock source. The clock source can be configured using the CKSEL fuses or the CLKPS bits in the CLKPR register.
  • The maximum frequency for the ATTINY461A-SU is 20 MHz, but it can be operated at lower frequencies by dividing the clock frequency using the CLKPR register.
  • The ADC on the ATTINY461A-SU is a 10-bit successive approximation ADC. It can be enabled by setting the ADEN bit in the ADCSRA register, and the ADC conversion can be started by setting the ADSC bit in the ADCSRA register.
  • Yes, the ATTINY461A-SU has several power-saving features, including sleep modes, power reduction registers, and a low-power oscillator. These features can be used to minimize power consumption and extend battery life in low-power applications.
