Ordering Information
The ordering code for Infineon microcontrollers provides an exact reference to the
required product. This ordering code identifies:
• the derivative itself, i.e. its function set, the temperature range, and the supply voltage
• the package and the type of delivery.
For the available ordering codes for the C167CR please refer to the “Product Catalog
Microcontrollers”, which summarizes all available microcontroller variants.
Note: The ordering codes for Mask-ROM versions are defined for each product after
verification of the respective ROM code.
Introduction
The C167CR derivatives are high performance derivatives of the Infineon C166 Family
of full featured single-chip CMOS microcontrollers. They combine high CPU
performance (up to 16.5 million instructions per second) with high peripheral functionality
and enhanced IO-capabilities. They also provide clock generation via PLL and various
on-chip memory modules such as program ROM, internal RAM, and extension RAM.
