Procurement Notes
Verify the suffix MBT-VAO indicates specific automotive qualification and tape-and-reel packaging. Confirm the manufacturer datasheet for exact moisture sensitivity level and reflow soldering profiles. Ensure the order matches the required operating temperature range and package variant.
Selection Notes
Select this component when ISO 26262 compliance is mandatory for the design. Compare against standard ATtiny816 variants if automotive qualification is not required. Verify pin compatibility with existing footprints as the QFN20 package dimensions must match the PCB layout constraints.
Part Context
This part belongs to the tinyAVR 1 family, which emphasizes low power consumption and functional safety. It shares architectural similarities with other members like the ATtiny817 but offers specific memory configurations optimized for cost-sensitive automotive and industrial applications requiring robust error handling.
Replacement Considerations
Direct substitutes include ATtiny816-MFR or ATtiny816-MFU for non-automotive use. For equivalent automotive-grade parts, verify ATtiny816-MFR-VAO availability. Cross-reference pinouts to ensure mechanical compatibility before substitution.
