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 C164CI 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 C164CI derivatives of the Infineon C166 Family of full featured single-chip CMOS
microcontrollers are especially suited for cost sensitive applications. They combine high
CPU performance (up to 12.5 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 or OTP, internal RAM, and
extension RAM.
