C161RI

Introduction

The C161RI is a new derivative of the Siemens C166 Family of 16-bit single-chip CMOS

microcontrollers. It combines high CPU performance (up to 8 million instructions per second) with

high peripheral functionality and enhanced IO-capabilities. The C161RI derivative is especially

suited for cost sensitive applications.

Ordering Information

The ordering code for Siemens microcontrollers provides an exact reference to the required

product. This ordering code identifies:

the derivative itself, i.e. its function set

the specified temperature range

the package

the type of delivery.

For the available ordering codes for the C161RI please refer to the

“Product Information Microcontrollers”, which summarizes all available microcontroller variants.

Note: The ordering codes for the Mask-ROM versions are defined for each product after

verification of the respective ROM code.
