Microchip Technology ATAVRFEB-SAFETY Safety Field Engagement Board

Microchip ATAVRFEB-SAFETY, Functional Safety Field Engagement Board, is based on the ATtiny3217 microcontroller (MCU). The AVR Functional Safety board is designed to easily demonstrate and evaluate the safety and reliability peripherals on the ATtiny3217 MCU. This board demonstrates the various built-in safety features of the AVR® microcontroller. These features include Watchdog Timer (WDT), Cyclic Redundancy Check (CRC), Brown-out Detection (BOD), Voltage Level Monitoring (VLM), Power-on Reset (POR), and Timer/Counter type D (TCD) fault detection.


  • Core Independent Operation Using Configurable Custom Logic (CCL) and 16-bit Timer/Counter Type A to Create a 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 the Voltage to ATtiny3217, Demonstrating Voltage Level Monitor (VLM) Interrupt, Brown-out Detector (BOD), and Power-on Reset (POR)
  • Onboard Mini Embedded Debugger (mEDBG) for Programming and Debugging
