3.5.1 Temperature Sensor

A clarification has been made to remove documentation from the following ADC sections related to a temperature sensor (TEMPSENSE) as the ATtiny3216/3217 Automotive devices do not have any internal temperature sensor.

  • Features
  • Block Diagram
  • Temperature Measurement

The affected ADC sections are listed below, with functional corrections shown in bold.

Features

  • 10-Bit Resolution
  • 0V to VDD Input Voltage Range
  • Multiple Internal ADC Reference Voltages
  • External Reference Input
  • Free-Running and Single Conversion Mode
  • Interrupt Available on Conversion Complete
  • Optional Interrupt on Conversion Results
  • Temperature Sensor Input Channel
  • Optional Event-Triggered Conversion
  • Window Comparator Function for Accurate Monitoring or Defined Thresholds
  • Accumulation of up to 64 Samples per Conversion

Block Diagram

The analog input channel is selected by writing to the MUXPOS bits in the MUXPOS (ADCn.MUXPOS) register. Any ADC input pins, GND, internal Voltage Reference (VREF), or temperature sensor, can be selected as a single-ended input to the ADC. The ADC is enabled by writing a ‘1’ to the ADC ENABLE bit in the Control A (ADCn.CTRLA) register. The voltage reference and input channel selections will not take effect before the ADC is enabled. The ADC does not consume power when the ENABLE bit in ADCn.CTRLA is ‘0’.
