Power Supply:
- Ensure the supply voltage is within the specified range (1.8V to 5.5V).
- Use appropriate decoupling capacitors near the power pins to minimize noise.
Clock Configuration:
- The device can be configured to use an internal oscillator or external crystal/clock source.
- For precise timing applications, configure the external crystal oscillator.
Programming:
- Use an ISP programmer or bootloader to upload code to the flash memory.
- Ensure correct settings for fuse bits to avoid programming issues.
Peripheral Setup:
- Initialize ADC, UART, SPI, TWI peripherals as required by your application.
- Configure pin modes and interrupts in software for optimal performance.
Power Management:
- Utilize sleep modes to reduce power consumption when the MCU is idle.
- Enable watchdog timer for reliable operation in low-power states.
Debugging:
- Use debugWIRE or JTAG for debugging purposes.
- Ensure proper connections and settings for debugging interfaces.
Storage Conditions:
- Store in a dry environment to prevent moisture damage.
- Handle with care to avoid static discharge which can damage sensitive components.
