• Integrated full-function Controller Area Network (CAN) interface compliant with Rev. 2.0B
• On-chip OTP program memory allowing in-system or external programming
• Comprehensive peripheral set including ADC, timers, and flexible I/O ports

Applications

• Automotive electronic control units
• Industrial automation systems
• Communication equipment requiring CAN bus connectivity

Procurement Notes

Verify component authenticity through authorized Infineon distributors or certified partners. Confirm the specific ordering suffix matches the required package and delivery format. Check for obsolescence status as older derivatives may be discontinued. Ensure environmental compliance documentation is available for your region. Validate that the OTP programming requirements align with your manufacturing process capabilities.

Selection Notes

Select this derivative when a 16-bit architecture with integrated CAN functionality is required. Consider the 64 KByte OTP capacity for applications needing field-updatable firmware. Evaluate the 25 MHz clock speed against real-time processing demands. Ensure the 80-pin MQFP package fits the board layout constraints. Verify power supply voltage compatibility with the system design.

Part Context

This component belongs to the Infineon C164CI/SI/C164CL/SL series within the broader C166 microcontroller family. These devices are designed for cost-sensitive applications combining high CPU performance with rich peripheral integration. The C164CI specifically targets automotive and industrial markets requiring robust communication interfaces like CAN.

Replacement Considerations

Consult official Infineon documentation for qualified replacement part numbers. Verify pin-to-pin compatibility and functional equivalence before substitution. Review updated datasheets for any changes in electrical characteristics or package options.
