General Description 
The CO4011 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. 
CO4011 provides up to 32 digital I/O lines, 0, 4 or 8 
channels may be set for analog input operation with 
a resolution of 8 or 10 bit. To support output overload 
monitoring, a special error interrupt input is provided. 
All usual baud rates up to 1 MBit are supported.  
The CO4011 Chip requires only few external compo-
nents, just like a crystal, a CAN transceiver and 
capacitors. 
To 
minimize 
recommendations all output pins have high current 
drive capability of 4 mA. For interfacing optoisolators 
no external drivers are required.

CO4011 is a software solution to run on Fujitsu 
MB90F497 micro controller. It is offered either as 
software runtime licence or as ready programmed 
chip (runtime licence included).
