Note Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage of 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  longer periods may affect device reliability. During overload conditions (V_IN > V_CC or VIN < V_SS)theVoltageonV_CC pins with respect to ground (V_SS) must not exeed the values definded by the absolute maximum ratings.


Description

The SAB 80C517/80C537 is a high-end member of the Siemens SAB 8051 family of microcontrollers. SAB 80C537 is designed in Siemens ACMOS technology and based on the SAB 8051 architecture. ACMOS is a technology which combines high-speed and density characteristics with low-power consumption or dissipation.

While maintaining all the SAB 80C515 features and operating characteristics the SAB 80C517 is expanded in its arithmetic capabilities, "fail-safe" characteristics, analog signal processing and timer capabilities. The SAB 80C537 is identical with the  SAB 80C517 except that it lacks the on-chip program memory. The SAB 80C517/SAB 80C537 is supplied in a 84 pin plastic leaded chip carrier package (P-LCC-84) and in a 100-pin plastic quad metric flat package (P-MQFP-100-2).
