Ordering Information
The ordering code for Infineon microcontrollers provides an exact reference to the
required product. This ordering code identifies:
•
•
•
•
the derivative itself, i.e. its function set
the specified temperature range
the package
the type of delivery.
For the available ordering codes for the
C161PI
please refer to the
„Product
Catalog Microcontrollers“,
which summarizes all available microcontroller
variants.
Note: The ordering codes for Mask-ROM versions are defined for each product after
verification of the respective ROM code.

Introduction
The C161PI is a derivative of the Infineon C166 Family of 16-bit single-chip CMOS
microcontrollers. It combines high CPU performance (up to 8 million instructions per
second) with high peripheral functionality and enhanced IO-capabilities. The C161PI
derivative is especially suited for cost sensitive applications.
