SAF-C509-LM

Product Summary

The SAF-C509-LM is a high-end microcontroller in the Siemens C500 8-bit microcontroller family. It 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. Further, the SAF-C509-LM is a superset of the Siemens SAB 80C517/80C517A 8-bit microcontroller thus offering an easy upgrade path for SAB 80C517/80C517A users. The high performance of the SAF-C509-LM microcontroller is achieved by the C500-Core with a maximum operating frequency of 16 MHz internal (and external) CPU clock.
