The C509-L is a high-end microcontroller in the Siemens C500 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. Further, the C509-L is a superset of the Siemens SAB 80C517/80C517A 8-bit microcontroller thus offering an easy upgrade path for SAB 80C517/80C517A users.
