C167CR
Highly Integrated
Microcontroller with On-chip
CAN-Module
The C167CR* is a new derivative
of the Siemens C166 family of full
featured single-chip CMOS micro-
controllers. It combines high CPU
performance with high peripheral
functionality and enhanced IO-
capabilities.
The C167CR features a CAN
module which meets version 2.0 B
active of the Controller Area
Network specification and was
designed to fulfill the require-
ments of coming generations
of automotive and industrial
control applications.
