ATTINY44-20PU Frequently Asked Questions (FAQs)

  • The ATTINY44-20PU can operate from -40°C to +125°C, but the recommended operating temperature range is -40°C to +85°C.
  • The ATTINY44-20PU can be programmed using a variety of methods, including In-System Programming (ISP), High-Voltage Serial Programming (HVSP), and Parallel Programming. You can use a programmer such as the AVRISP or the PICkit, or use a development board like the Arduino.
  • The ATTINY44-20PU has a maximum clock speed of 20 MHz, but it can also be operated at lower clock speeds to reduce power consumption.
  • The power consumption of the ATTINY44-20PU depends on the clock speed, operating voltage, and other factors. At 20 MHz and 5V, the typical current consumption is around 15 mA, but it can be as low as 0.1 mA in sleep mode.
  • Yes, the ATTINY44-20PU can operate from a 3.3V power supply, but the maximum clock speed is limited to 12 MHz at this voltage.
