• Manufacturer Part Number: SAH-C515
• Description: 8-Bit CMOS Microcontroller
• Manufacturer: SIEMENS [Siemens Semiconductor Group]

The C515 is a member of the Siemens C500 family of 8-bit microcontrollers. lt is functionally fully
upward compatible with the SAB-80C515/80C535 microcontrollers.
The C515 basically operates with internal and/or external program memory. The C515-L is identical
to the C515-1R, except that it lacks the on-chip porgram memory. Therefore, in this documentation
the term C515 refers to all versions within this specification unless otherwise noted.
Figure 1-1 shows the different functional units of the C515 and figure 1-2 shows the simplified logic
symbol of the C515.
