The C161S is a derivative of the Infineon C166 Family of full featured single-chip CMOS microcontrollers. It combines high CPU performance (up to 12.5 million instructions per second) with high peripheral functionality and enhanced IO-capabilities. It also provides clock generation via PLL and power management features. The C161S is especially suited for cost sensitive applications.
