2. Electromagnetic Compatibility

Electromagnetic compatibility (EMC) performance is highly dependent on The environment where the MCU is located. Board Design and Layout, Circuit Topology Selection, location and characteristics of external components and MCU software Operation plays an important role in EMC performance.

3. Thermal characteristics

For operating temperature range, power dissipation, and package thermal resistance. Power consumption on I/O pins is generally small Power consumption in on-chip logic and voltage regulator circuits, which is determined by the user and not controlled by the MCU design. Taking PI/O into account for power calculations, determine the difference between the actual pin voltage and VSS or VDD and multiply by the pin current for each I/O pin. The difference between pin voltage and VSS or VDD can be large unless under abnormally high pin current (heavy load) small.
