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 (VIN > VCC or V IN < VSS) theVoltage on VCC pins with respect to ground (VSS ) must not exeed the values definded by the absolute maximum ratings.

The SAB SAB80C517A is a high-end member of the Siemens SAB 8051 family of microcontrollers. It is designed in Siemens ACMOS technology and based on SAB 8051 architecture. ACMOS is a technology which combines high-speed and density characteristics with low-power consumption or dissipation.

While maintaining all the SAB80C517A features and operating characteristics the SAB 80C517A is expanded in its "fail-safe" characteristics and timer capabilities.The SAB 80C517A is identical with the SAB 83C517A-5 except that it lacks the on-chip program memory. The SAB80C517A is supplied in a 84-pin plastic leaded chip carrier package (P-LCC-84) and in a 100-pin plastic quad flat package (P-MQFP-100-2).The SAB80C517A is based on 8051 architecture. It is a fully compatible member of the Siemens SAB80C517A microcontroller family being an significantly enhanced SAB 80C517. The SAB80C517A is therefore compatible with code written for the SAB80C517.Having an 8-bit CPU with extensive facilities for bit-handling and binary BCD arithmetics the SAB 80C517A is optimized for control applications. With a 18 MHz crystal, 58 % of the instructions are executed in 666.67 ns.

Being designed to close the performance gap to the 16-bit microcontroller world, the SAB80C517A's CPU is supported by a powerful 32-/16-bit arithmetic unit and a more flexible addressing of external memory by eight 16-bit datapointers.
