Rev. 2 September 2013 1/32 UM0162 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. Main Features ■ 20-bit digital interface for 2-, 3-wire sensors or mechanical contact using CLT3-4BT6 and PCLT-2A Te rminations supporting Type 1, 2 or 3 input characteristics according to IEC61131-2 specifications ■ 24-bit digital output interface supporting VN340 and VN808 Reference Design Boards ■ 16-bit ST10F269 microcontroller with a C166 core @ 40MHz ■ ST202E RS-232 Transceiver with 15kV guaranteed ESD protection ■ ST485A Very High-speed Low-power RS-485 Transceiver interface with bit rate up to 30Mbps ■ Two L9616 High-speed CAN Bus Transceiver with bit rate up to 1Mbps ■ STM811 Reset Circuit ■ LF50 Very Low Dropout Voltage Regulator ■ 6 to 16V DC Supply Voltage
