Procurement Notes

Verify the exact ordering code against official Infineon documentation to ensure correct package type and delivery format. Confirm that the specific suffix matches the required temperature range and voltage specifications. Check current product status as older derivatives may be discontinued or subject to last-time buy notices.

Selection Notes

Select this component when a 16-bit architecture with high interrupt response times is required. Ensure the design utilizes the available 2 KBytes of on-chip RAM and fits within the 80-pin MQFP footprint. Verify compatibility with the 4.5 V to 5.5 V power supply requirements and check if the external bus controller modes meet memory expansion needs.

Part Context

This part belongs to the C161K/O derivative group within the broader C166 Family. It shares architectural similarities with other members but differs in specific memory sizes and peripheral counts. The C161O variant specifically provides enhanced I/O capabilities compared to the C161K model.

Replacement Considerations

Consult the official C161K/O Derivative Synopsis table for cross-references. Potential substitutes include other C166 family members with similar pinouts and performance characteristics, provided they match the specific memory and peripheral requirements.
