Procurement Notes
Verify the specific suffix MMUR corresponds to the tape and reel packaging configuration required for automated assembly processes. Confirm that the component meets RoHS compliance standards applicable to your manufacturing region. Ensure compatibility with surface-mount technology reflow profiles specified in the official datasheet thermal guidelines.
Selection Notes
Select this component when an 8-bit AVR core with moderate program memory capacity is required. Consider the 28-VQFN package dimensions for PCB layout constraints. Evaluate the 1.8 V to 5.5 V operating range against the target system power supply stability requirements.
Part Context
This part belongs to the ATmega88PA family, which offers enhanced power efficiency compared to previous generations. The PA designation indicates optimized power consumption characteristics suitable for battery-operated applications. It shares architectural similarities with other members of the megaAVR series while providing specific memory and pin configurations.
Replacement Considerations
Direct substitutes include ATMEGA88PA-MU or ATMEGA88PA-MMHR, provided the package type and termination finish match the design requirements. Verify electrical specifications and pinout compatibility before substitution.
