CANopen Chip CO411xA

frenzel + berg CO4201 CANopen Single Chip IO Controller with PWM Function

The CO411x-FL 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.

CO411X provides up to 32 digital I/O lines, 8 channels convert analog input signals with a resolution of 10 bit. 8 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 CO411X Chip requires only few external components, just like a crystal, a CAN transceiver and capacitors.

The CO411x has several compatibility modes in order to replace the CO4011 and CO4017 controllers.
