הערות תכנון
Decouple the VDD pin with a 100nF ceramic capacitor placed as close as possible to the pin, and a 1uF capacitor for bulk decoupling. The supply voltage range is 2.95V to 5.5V; ensure the supply is stable and within this range to avoid brown-out resets. The device has an internal brown-out reset (BOR) that monitors VDD and resets the MCU if the voltage drops below a threshold, but external filtering is still recommended for noisy environments.
For the NRST pin, connect a 100nF capacitor to ground and a 10k ohm pull-up resistor to VDD to prevent spurious resets from noise. The SWIM pin (PD1) is used for programming and debugging; keep the trace short and avoid routing high-speed signals nearby. For the crystal oscillator (if used), place the crystal and load capacitors close to the OSC pins and keep the traces short to minimize parasitic capacitance. Ensure a solid ground plane under the MCU to reduce EMI.
Do not leave unused I/O pins floating; configure them as outputs or enable internal pull-ups to reduce current consumption and avoid undefined states. The ADC input pins have a maximum input voltage of VDD; ensure external signals do not exceed this. When using the internal RC oscillator, note that accuracy is +/-2% over temperature, which may be insufficient for time-critical applications; use an external crystal for better accuracy. Also, the EEPROM has a limited write endurance (100k cycles), so avoid frequent writes in high-cycle applications.
