• Manufacturer Part Number: SAB80C515A-5
• Description: 8-Bit CMOS Single-Chip Microcontroller Family
• Manufacturer: SIEMENS [Siemens Semiconductor Group]

The SAB 80C515A is available in two different versions:
With exception of the ROM sizes both parts are identical. Therefore the term SAB 80C515A refers
to both versions within this specification unless otherwise noted.
This manual describes only the new features of the SAB 80C515A in addition to the features of the
SAB 80C515/80C535. For reference to the SAB 80C515, the user's manual should be used.
Listed below is a summary of the main features of the SAB 80C515A:
The pin functions of the SAB 80C515A are identical with those of the SAB 80C515 with following
exceptions:
Pin 68
Pin 1
Pin 4
