One of each type of motor is included along with necessary cables and power supplies. SmartFusion cSoCs are the only devices that integrate an FPGA, an ARM® Cortex™-M3 processor, and programmable analog, offering full customization, IP protection, and ease- of-use. The device contains on-chip flash and on-chip SRAM memory, as well as additional SPI flash memory on the board. SmartFusion FPGA fit well to motion control applications. Due to the combination of hardware, software, and additional analog components complex systems can be integrated within a single chip. This drastically reduces the number of required components to realize a motion control unit. Real time critical tasks can be implemented in hardware. Complex - but less real time critical tasks - can be realized in software. Real Time critical tasks are commutation of fast rotating BLDC motors or processing of high resolution encoder signals. Processing of analog signals, e.g., voltage and current measurement is a typical task in motion control applications. Therefore, the SmartFusion’s. analog I/Os and processing functionality can be used.
