2.1 Introduction
The C167CR derivatives are high performance derivatives of the Infineon C166 Family
of full featured single-chip CMOS microcontrollers. They combine high CPU
performance (up to 16.5 million instructions per second) with high peripheral functionality
and enhanced IO-capabilities. They also provide clock generation via PLL and various
on-chip memory modules such as program ROM, internal RAM, and extension RAM.
