Procurement Notes

Verify the exact suffix against official documentation, as variations may indicate different temperature ranges or packaging types. Confirm current manufacturing status, as this specific part number may be discontinued or superseded by newer equivalents. Ensure compatibility with existing board layouts and software drivers designed for the C166 architecture before procurement.

Selection Notes

Select this component when a 16-bit MCU with external memory capability is required. Consider the C166 core performance and available I/O count relative to system needs. Evaluate the need for external oscillators versus internal options found in other variants. Check for pin-compatible alternatives if form factor constraints exist.

Part Context

This microcontroller belongs to the Infineon C166 family, widely used in automotive and industrial sectors. The C16xx sub-series typically targets cost-sensitive applications requiring robust 16-bit processing without integrated on-chip program memory. It serves as a foundational controller for systems needing reliable peripheral management and external bus interfacing.
