AVR Functional Safety

Part Number: ATAVRFEB-SAFETY

Summary:

The Functional Safety Field Engagement Board is based on the ATtiny3217 microcontroller demonstrating the various built-in safety features of the AVR® microcontroller, such as:

  • Power-on Reset (POR), Brown-out Detection (BOR), Voltage Level Monitoring (VLM) to ensure sufficient supply voltage.
  • Cyclic Redundancy Check (CRC) to ensure no code

Product Features

    • Core independent operation using Configurable Custom Logic (CCL) and 16-Bit Timer/Counter Type A to create heartbeat signal
    • Core independent Cyclic Redundancy Check Memory Scan (CRCSCAN)
    • Core independent operation using 12-Bit Timer/Counter Type D (TCD) to drive a fan motor
    • Core independent TCD fault handling using Event System (EVSYS), Analog Comparator (AC) and Digital-to-Analog Converter (DAC)
    • Using Charlieplexing technique to drive a large number of LEDs with a low number of pins, using 16-Bit Timer/Counter Type B (TCB) and priority interrupt
    • Demonstrating core independent Watchdog Timer (WDT) in window mode
    • Demonstrating Real Time Counter Periodic Interrupt (RTC) (PIT)
    • Board controller with (PTC) touch slider to adjust voltage to ATtiny3217, demonstrating Voltage Level Monitor (VLM) interrupt, Brown-out Detector (BOD) and Power-on Reset (POR)
    • On-board Mini Embedded Debugger (mEDBG) for programming and debugging

Summary

The Functional Safety Field Engagement Board is based on the ATtiny3217 microcontroller demonstrating the various built-in safety features of the AVR® microcontroller, such as:

  • Power-on Reset (POR), Brown-out Detection (BOR), Voltage Level Monitoring (VLM) to ensure sufficient supply voltage.
  • Cyclic Redundancy Check (CRC) to ensure no code corruption.
  • Windowed Watchdog Timer (WDT) monitoring correct program operation.
  • Timer/Counter type D (TCD) fault detection.
  • Class B self tests designed to detect various faults on start-up or during program execution, and shut down the application safely in case of fault.
