C161K
C161O
Data Sheet 2 V2.0, 2001-01
This document describes several derivatives of the C161 group. Table 1 enumerates
these derivatives and summarizes the differences. As this document refers to all of these
derivatives, some descriptions may not apply to a specific product.
For simplicity all versions are referred to by the term C161K/O throughout this document.
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 C161K/O 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.
