Introduction
The SAB 80C166W/83C166W is a representative of the Siemens SAB 800166 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. These
devices derive the CPU clock signal (operating clock) directly from the on-chip oscillator without
using a prescaler. This reduces the device's EME.
