Introduction

The C164SV derivatives of the Infineon C166 Family of full featured single-chip CMOS microcontrollers are especially suited for cost sensitive applications. They combine high CPU performance (up to 12.5 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 and internal RAM.
