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.

Absolute Maximum Ratings

Ambient temperature under bias (T_A):

SAB 83C166-5M, SAB 80C166-M..................................................................................0 to + 70 ˚C

SAB 83C166-5M-T3, SAB 80C166-M-T3 .................................................................. – 40 to + 85 ˚C

Storage temperature (T_ST) ....................................................................................... – 65 to + 150 ˚C

Voltage on V_CC pins with respect to ground (V_SS) ..................................................... – 0.5 to + 6.5 V

Voltage on any pin with respect to ground (V_SS).................................................– 0.5 to V_CC + 0.5 V

Input current on any pin during overload condition.................................................. – 10 to + 10 mA

Absolute sum of all input currents during overload condition ..............................................|100 mA|

Power dissipation........................................................................................................................ 1 W

Note: Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. During overload conditions (VIN > VCC or VIN < VSS) the voltage on pins with respect to ground (VSS) must not exceed the values defined by the Absolute Maximum Ratings.
