The SAB 80C515A/83C515A-5 is a high-end member of the Siemens SAB 8051 microcontroller family. It 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 80C515A/83C515A-5 contains more on-chip RAM/ROM. Furthermore a new 10-bit A/D Converter is implemented as well as extended security mechanisms. The SAB 80C515A is identical with the SAB 83C515A-5 except that it lacks the on-chip program memory. The SAB 80C515A / 83C515A-5 is supplied in a 68-pin plastic leaded chip carrier package (P-LCC- 68) and in a 80-pin plastic metric quad flat package (P-MQFP-80).
Versions for extended temperature range – 40 to + 110 ∞C are available on request.
