Absolute Maximum Ratings

  • VDD2: The microcontroller’s input supply voltage range. To function properly, it should be between 2.7 V and 5.5 V. It is not permitted to go below -0.3 V or above 5.8 V.
  • VREFH: The high reference voltage for the Analog-to-Digital Converter (ADC) inputs is specified by this parameter. It should be between 3.3 and 5.0 volts. The absolute upper and lower limits are -0.3 V and 5.8 V.
  • IINJPAD_DC_ABS: This variable represents the continuous DC input current (negative positive or) that can be injected into an I/O pin. The permissible range is -3 to +3 mA.
  • VIN_DC: The continuous DC voltage that can be applied to any I/O pin with respect to ground (VSS) is specified by this parameter. The voltage should range between -0.8 V and 5.85 V.
  • IINJSUM_DC_ABS: Under continuous DC conditions, the sum of the absolute value of injected currents on all pins shall not exceed 30 mA.
  • Tramp_MCU: The rate at which the ECU supply voltage can increase is defined as the ramp rate. It should not be higher than 0.5 V/min or 500 V/ms.
  • Tramp_MCU: The MCU supply ramp rate determines how quickly the microcontroller supply voltage can rise. It should not be higher than 0.5 V/min or 100 V/ms.
  • TA: Ambient temperature is the microcontroller’s permitted operating temperature range, which ranges from -40°C to 125°C. Operating the gadget outside of this range may result in problems.
  • TSTG: Storage temperature range indicates the temperature range for safe microcontroller storage, which should be between -55°C and 165°C.
  • VIN_TRANSIENT: The transient overshoot voltage allowed on an I/O pin beyond the VIN_DC limit is specified by this parameter. It should not be higher than 6.8 V.

These absolute maximum ratings are critical for guaranteeing the microcontroller’s reliable and safe performance in a variety of environmental conditions and use scenarios. Excessive use of these restrictions might cause device malfunction, decreased lifespan, or irreversible damage, thus they must be properly followed during design and operation.
