ATTINY44-20SSU Frequently Asked Questions (FAQs)

  • The ATTINY44-20SSU can operate from -40°C to +85°C, but the recommended operating temperature range is 0°C to +70°C for optimal performance.
  • The ATTINY44-20SSU can be programmed using a variety of methods, including in-system programming (ISP), in-circuit serial programming (ICSP), and high-voltage serial programming (HVSP). You can use a programmer such as the AVRISP or the PICkit 3, or use a development board with a built-in programmer.
  • The ATTINY44-20SSU can operate at a maximum clock speed of 20 MHz, but it can also be clocked at lower speeds to conserve power.
  • The ATTINY44-20SSU has a typical active mode current consumption of 1.5 mA at 1 MHz and 3V, and a typical sleep mode current consumption of 0.1 μA at 3V.
  • Yes, the ATTINY44-20SSU has a built-in 10-bit analog-to-digital converter (ADC) with 8 channels, which can be used to convert analog signals to digital values.
