Ordering Information
The ordering code for Siemens microcontrollers provides an exact reference to the required
product. This ordering code identifies:
•
the derivative itself, i.e. its function set
•
the specified temperature range
•
the package and the type of delivery.
For the available ordering codes for the C517A please refer to the
„Product
Information Microcontrollers“,
which summarizes all available microcontroller variants.
Note: The ordering codes for the Mask-ROM versions are defined for each product after
verification of the respective ROM code.
