Introduction

The members of the C500 Siemens microcontroller family are basically fully compatible in
architecture and software to the standard 8051 microcontroller family. Especially, they are
functionally upward compatible to the SAB 80C52/80C32 microcontroller. While maintaining all
architectural and operational characteristics of the SAB 80C52/80C32, the C500 microcontrollers
differ in number and complexity of their peripheral units which have been adapted to the specific
application areas.
The goal of this ÒArchitecture and Instruction Set ManualÒ is to summarize the basic architecture
and functional characteristics of all members of the C500 microcontroller family. This includes the
description of the architecture and the description of the complete instruction set. Detailed
information about the different versions of the C500 microcontrollers are given in the specific User
Manuals.
