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.
The high performance of the C509-L microcontroller is achieved by the C500-Core with a maximum
operating frequency of 16 MHz internal (and external) CPU clock. While maintaining all the features
of the SAB 80C517A, the C509-L is expanded by one I/O port, in its compare/capture capabilities,
by A/D converter functions, by additional 1 KByte of on-chip RAM (now 3 KByte XRAM) and by an
additional user-selectable CMOS port structure. The C509-L is mounted in a P-MQFP-100-2
package.
