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

2
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 C515 is an upward compatible version of the SAB 80C515A 8-bit microcontroller which
additionally provides ALE switch-off capability, on-chip emulation support, ROM protection, and
slow down mode capability. With a maximum external clock rate of 24 MHz it achieves a 500 ns
instruction cycle time (1
µ
s at 12 MHz). The C515 is mounted in a P-MQFP-80 package.
