Packing
Please use the recycling operators known to you. We can also help you – get in touch with your nearest sales office. By agreement we
will take packing material back, if it is sorted. You must bear the costs of transport.
For packing material that is returned to us unsorted or which we are not obliged to accept, we shall have to invoice you for any costs in-
curred.
Components used in life-support devices or systems must be expressly authorized for such purpose!
Critical components

with the express
written approval of the Semiconductor Group of Siemens AG.
1 A critical component is a component used in a life-support device or system whose failure can reasonably be expected to cause the
failure of that life-support device or system, or to affect its safety or effectiveness of that device or system.
2 Life support devices or systems are intended (a) to be implanted in the human body, or (b) to support and/or maintain and sustain hu-
man life. If they fail, it is reasonable to assume that the health of the user may be endangered.

The C515A is an upward compatible version of the SAB 80C515A/83C515A-5 8-bit microcontroller
which additionally provides an improved 10-bit A/D converter, ALE switch-off capability, on-chip
emulation support, ROM protection, and enhanced power saving mode capabilities. With a
maximum external clock rate of 24 MHz it achieves a 500 ns instruction cycle time (1
µ
s at 12 MHz).
The C515A is mounted in a P-MQFP-80 package.
