Procurement Notes
This component is officially marked as obsolete and no longer manufactured by Infineon Technologies. Sourcing should focus on verified surplus distributors or secondary market suppliers. Buyers must verify part authenticity and condition carefully due to the end-of-life status. Availability is limited and subject to stock fluctuations. Ensure compatibility with existing designs before procurement.
Selection Notes
Select this part only if legacy C166 architecture compatibility is required. Consider modern alternatives like the AURIX family for new designs. Verify pinout and voltage levels match the target application. Check for sufficient I/O count and peripheral availability. Evaluate long-term supply chain risks associated with obsolete components.
Part Context
Part of the C16xx family, designed for high-performance 16-bit applications. Uses PG-TQFP-100-1 packaging. Supports standard automotive and industrial temperature ranges. Includes power-on reset, PWM, and watchdog timer peripherals.
Replacement Considerations
No direct public substitute part numbers are confirmed for this specific variant. Review Infineon's C161PI datasheet for potential cross-references. Consider migration to newer MCU families for sustained production support.
