Procurement Notes

Verify part status as obsolete before procurement planning. Confirm availability of qualified substitutes such as the XMC4400F100K512BAXQMA1. Ensure compatibility with existing design constraints when transitioning to replacement components. Validate all specifications against official datasheets prior to implementation.

Selection Notes

Select this component for applications requiring a 16-bit C166 core with external memory expansion due to its ROMless nature. Consider the 100-pin MQFP package for board space requirements. Verify that the 20 MHz speed and 4.5V to 5.5V supply range meet system specifications. Check peripheral needs against available SPI and USART channels.

Part Context

This microcontroller belongs to the C16xx family, designed primarily for automotive and industrial markets. The C166 core provides a balance of performance and efficiency for complex control tasks. The series is known for robust integration of communication interfaces suitable for networked environments.

Replacement Considerations

The XMC4400F100K512BAXQMA1 is listed as a similar substitute. Evaluate architectural differences between the legacy C166 core and modern alternatives. Assess pinout compatibility and software migration efforts required for replacement.
