C164CI

Introduction

The C164CI is a new low cost 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. It also provides on-chip ROM or OTP

and clock generation via PLL. The C164CI 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, ie. its function set

the specified temperature range

the package

the type of delivery.

For the available ordering codes for the C164CI 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.
