ATTINY461-20SU Frequently Asked Questions (FAQs)

  • The ATTINY461-20SU can operate from -40°C to +125°C, but the recommended operating temperature range is -40°C to +85°C for optimal performance.
  • The ATTINY461-20SU 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 ATTINY461-20SU is 20 MHz, but it can be operated at lower frequencies by dividing the clock frequency using the CLKPR register.
  • The ATTINY461-20SU can be programmed using a variety of methods, including in-system programming (ISP), high-voltage serial programming (HVSP), and parallel programming. The device can also be programmed using a programmer or a development board.
  • The power consumption of the ATTINY461-20SU depends on the operating frequency, voltage, and mode of operation. In active mode, the device consumes around 1.5 mA at 1 MHz and 5V. In power-down mode, the device consumes around 0.1 μA.
