The CO4201 is a low cost, high performance Single Chip solution for CANopen remote I/O modules and especially designed for automotive and industrial applications. The device offers the complex implementation of the CANopen standards DS301 and DS401 in a single chip. It is suitable for simple low cost applications like sensor interfacing as well as for complex I/O systems.

CO4201 provides up to 27 input lines, 8 channels convert analog input signals with a resolution of 12 bit. 18 output lines are provided. 2 output lines may be used as analog voltage output lines with a resolution of 10 bit. 6 output lines support PWM generation.

To support output overload monitoring, a special error interrupt input is provided. All usual baud rates up to 1 MBit are supported.

The CO4201 Chip requires only few external components, just like a crystal, a CAN transceiver and capacitors. To minimize external interface recommendations all output pins have high current drive capability of 4 mA. For interfacing opto isolators no external drivers are required.
