USER MANUAL
Getting Started with the CAN Industrial Controller Evaluation Board
using an ST10 MCU
Introduction
This user manual describes the implementation of Controller Area Network (CAN) Industrial Controller
(IC) applications based on a 16-bit microcontroller from STMicroelectronics’ ST10 family. ST10
microcontrollers have a C166 core that is compatible in industrial market segment. The CANIC10 can be
used as a simple programmable logic controller (PLC), master or slave node in a communication system
and as an evaluation board.
The CANIC10 is equipped with a sophisticated industrial sensor interface using a CLT3-4BT6 integrated
device, 5Volt CMOS level parallel output interface and several bus interfaces such as RS232, RS485 and
two CAN2.0B connections.
Output interface is compatible with VN808, VN808CM and VN340 Reference Design Boards (industrial
high-side drivers).
The system can be supplied either from a standard DC power supply (6 to 16V DC) or from a connected
VNxxx board.
The CANIC10 package includes a CD-ROM with the application program (Intel hex file), board fabrication
data (Gerber files), this user manual and other documentation for related devices.
