The CSC01 is based on the M16C 16-bit micro-controller from Renesas (formerly: Mitsubishi). It provides two CAN modules on-chip. The micro-controller implements the CANopen application layer (CiA DS 301 version 4.02) and the CANopen safety protocol (CiA DSP 304 version 1.0). The chip is suitable to be used for safety-relevant sensor as well as actuator device applications. It also can be used for safety-relevant control devices as communication processor optionally connected to the safety-relevant application processor. The CSC01 can be used for devices to be compliant with IEC 61508 – up to SIL 3 (safety integrity level). The chip has been submitted for TÜV approval.

The CSC01 features

• NMT slave functionality
• 2 SRDO to be transmitted
• 2 SRDO to be received
• GFC (global failsafe command)
• 2 PDO to be transmitted
• 2 PDO to be received
• 1 SDO server
• Emergency producer function
• Heartbeat producer function
• PDO linking capability
• Variable PDO mapping capability
• Asynchronous and synchronous PDO transmission

The CSC01 micro-controller in a QFP-100 housing runs at 16 MHz. It provides 10 KiB internal SRAM and 256 KiB Flash memory. Approximately 2.5 KiB SRAM and 10 KiB Flash memory are available for the user-specific safety application. The micro-controller is specified for operation in a temperature range from –40 °C to +85 °C.

The CSC01 starter kit is made of two single-board computer boards featuring the CSC01 CANopen safety chip and all necessary additional circuitry to connect simple safety-relevant input devices (e.g. emergency switch) or safety-relevant output devices (e.g. safety relay). The modules also provide simple watchdog circuits and power supply circuitries. The kit comes with cables and handbook.
