The SAB 80C517 is based on 8051 architecture. It is a fully compatible member of the Siemens
SAB 8051/80C51 microcontroller family being a significantly enhanced SAB 80C515. The
SAB 80C517 is therefore 100 % compatible with code written for the SAB 80C515.
Having an 8-bit CPU with extensive facilities for bit-handling and binary BCD arithmetics the
SAB 80C517 is optimized for control applications. With a 12 MHz crystal, 58% of the
instructions execute in 1 s.
Being designed to close the performance gap to the 16-bit microcontroller world, the
SAB 80C517’s CPU is supported by a powerful 32-/16-bit arithmetic unit and a more flexible
addressing of external memory by eight 16-bit datapointers.
According to the SAB 8051 architecture, the SAB 80C517 has separate address spaces for
program and data memory. Figure 2 illustrates the mapping of address spaces.
