Procurement Notes

Verify the specific suffix 'MUR' against the manufacturer's official documentation to confirm the reel packaging configuration and moisture sensitivity level. Ensure the component status is current for new designs, as availability may vary by region or distributor. Cross-reference the datasheet revision to confirm pinout and electrical characteristics match your schematic requirements before procurement.

Selection Notes

Select this component when a balance of moderate program memory and extensive I/O capabilities is required within a compact form factor. The 32-pin package provides sufficient pins for complex peripheral integration while maintaining a small footprint. Consider the power consumption profiles across different clock speeds and voltage levels to ensure compliance with system energy budgets.

Part Context

This part belongs to the ATtiny828 family of 8-bit AVR microcontrollers. It shares core architectural features with other devices in the series but offers specific memory sizes and package options. The MUR suffix typically denotes a tape and reel packaging variant suitable for automated surface-mount assembly processes.

Replacement Considerations

Consult the official Microchip compatibility matrix for verified substitutes. Direct pin-to-pin replacements may require verification of memory size and peripheral availability. Ensure any alternative component meets the same voltage, temperature, and interface specifications.
