Procurement Notes

This component is officially listed as obsolete and no longer manufactured by Infineon Technologies. Verification of availability should focus on distributor surplus stock or authorized secondary market channels. Buyers must confirm the specific revision status and ensure compatibility with existing design specifications before procurement, as direct manufacturing support is unavailable.

Selection Notes

Engineers selecting this part should consider its legacy status within the C16xx family. The absence of internal program memory requires external code storage solutions. Designers must verify that the 4.5 V to 5.5 V supply requirement aligns with system power rails. Alternative modern microcontrollers may offer enhanced performance and continued production support.

Part Context

The C165LF series belongs to Infineon's broader C166 microcontroller family, designed for high-performance embedded applications. This specific variant represents a ROMless version intended for systems requiring external program memory. The C166 architecture is known for its efficiency in digital signal processing and complex control tasks within industrial and automotive sectors.
