The SAB 80C517/80C537 is a high-end microcontroller in the Siemens SAB 8051 8-bit
microcontroller family. lt is based on the well-known industry standard 8051 architecture; a great
number of enhancements and new peripheral features extend its capabilities to meet the extensive
requirements of new applications. Nevertheless, the SAB 80C517 maintains compatibility within the
Siemens SAB 8051 family; in fact, the SAB 80C517 is a superset of the Siemens SAB 80C515/
80C535 microcontroller thus offering an easy upgrade path for SAB 80(C)515/80(C)535 users.
In addition to all features of the SAB 80C515, there are several enhancements for higher
performance. The SAB 80C517 has been expanded e.g. in its arithmetic characteristics, fail save
mechanisms, analog signal processing facilities and timer capabilities.
Listed below is a summary of the main features of the SAB 80C517/80C537:
Semiconductor Group
8 Kbyte on-chip program memory (SAB 80C517 only)
ROMIess version also available (SAB 80C537)
Full compatibility with SAB 80C515/80C535
256 byte on-chip RAM
256 directly addressable bits
