High-Performance
8-Bit CMOS Single-Chip Microcontroller

The SAB 80C517A/83C517A-5 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 SAB 80C517 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 SAB 80C517A/83C517A-5 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).
