Introduction
The rapidly growing area of embedded control applications is representing one of the
most time-critical operating environments for today’s microcontrollers. Complex control
algorithms have to be processed based on a large number of digital as well as analog
input signals, and the appropriate output signals must be generated within a defined
maximum response time. Embedded control applications also are often sensitive to
board space, power consumption, and overall system cost.
Embedded control applications therefore require microcontrollers, which:
• offer a high level of system integration
• eliminate the need for additional peripheral devices and the associated software overhead
• provide system security and fail-safe mechanisms
• provide effective means to control (and reduce) the device’s power consumption.
With the increasing complexity of embedded control applications, a significant increase
in CPU performance and peripheral functionality over conventional 8-bit controllers is
required from microcontrollers for high-end embedded control systems. In order to
achieve this high performance goal Infineon has decided to develop its family of 16-bit
CMOS microcontrollers without the constraints of backward compatibility.
Of course the architecture of the 16-bit microcontroller family pursues successful
hardware and software concepts, which have been established in Infineon’s popular
8-bit controller families.
About this Manual
This manual describes the functionality of a number of 16-bit microcontrollers of the
Infineon C166 Family, the C167-class.
As these microcontrollers provide a great extent of identical functionality it makes sense
to describe a superset of the provided features. For this reason some sections of this
manual do not refer to all the C167 derivatives that are offered (e.g. devices without on-
chip program memory). These sections contain respective notes wherever possible.
The descriptions in this manual refer to the following derivatives of the C167-class:
• C167CS-4RM Version with 32 KByte ROM
• C167CS-LM Version without on-chip program memory
This manual is valid for the versions with on-chip ROM of the mentioned derivatives as
well as for the ROMless versions. Of course it refers to all devices of the different
available temperature ranges and packages.
For simplicity all these various versions are referred to by the term C167CS throughout
this manual. The complete pro-electron conforming designations are listed in the
respective data sheets.
