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.
