• Manufacturer Part Number: SAB80C517-M16
• Description: 8-Bit CMOS Single-Chip Microcontroller
• Manufacturer: SIEMENS [Siemens Semiconductor Group]

The ROMIess version SAB 80C537 is identical with the SAB 80C517 except for the fact that it lacks
the on-chip program memory; the SAB 80C537 is designed for applications with external program
memory.
In this manual, any reference made to the SAB 80C517 applies to both versions, the SAB 80C517
and the SAB 80C537, unless otherwise noted.
Figure 1-1 shows the logic symbol of the SAB 80C517:
