• Integrated clock generation via on-chip PLL with selectable factors, prescaler, or direct clock input options.
• Comprehensive peripheral set including an 8-channel 10-bit A/D converter with programmable conversion times and CAPCOM2 units.

Applications

• Cost-sensitive embedded control systems
• Industrial automation controllers
• Automotive subsystems requiring robust I/O capabilities

Procurement Notes

Verify the specific suffix and package configuration against official Infineon documentation to ensure compatibility with your design requirements. Confirm availability status as product lifecycles may change. Cross-reference the exact part number with authorized distributors to avoid counterfeit components. Ensure that the selected variant meets all environmental and electrical specifications required for your target application environment.

Selection Notes

Select this component when a balance of high CPU performance and extensive peripheral functionality is needed within a cost-constrained design. The C166 architecture offers enhanced boolean bit manipulation and support for high-level languages. Consider the available on-chip memory sizes and the specific interface requirements, such as the need for PEC-based data transfer, before finalizing the choice.

Part Context

This microcontroller belongs to the C166 family, known for combining high processing power with rich peripheral integration. The C164CI derivatives are specifically optimized for applications where cost efficiency is critical without compromising on computational throughput or I/O flexibility. The architecture supports a 16 MBytes total linear address space for code and data.

Replacement Considerations

Consult official Infineon substitution guides for verified alternatives. Generic cross-references should be avoided due to potential differences in pinouts, memory configurations, and peripheral sets. Verify compatibility with existing development tools and software libraries if migrating from other members of the C166 family.
