SAB 80C166/83C166
Introduction
The SAB 80C166 is the first representative of the Siemens SAB 80C166 family of full featured
single-chip CMOS microcontrollers. It combines high CPU performance (up to 10 million
instructions per second) with high peripheral functionality and enhanced IO-capabilities.
