The C8051F85x/6x family is ideally suited for BLDC applications because of its best-in-class analog performance, small footprint and other features optimized for motor control designs. The cost-effective, high-performance 8051-based MCU spins the reference design kit’s 6-pole motor at a maximum speed of 50,000 rpm. The C8051F85x/6x MCU family also helps developers reduce overall system cost by eliminating the need for external components such as a crystal oscillator, voltage reference, level shifters, temperature sensor and other discretes.Silicon Labs’ sensorless BLDC reference design is designed to give developers a productive, comprehensive “out-of-box” experience, providing everything needed to get a motor spinning in less than five minutes. The reference design includes the following hardware and software tools:
- C8051F850 MCU control board providing the intelligence to drive the motor and associated peripherals
- Powertrain board with gate drivers and power MOSFETs
- Turnigy 450 Series 3800 kV BLDC outrunner motor attached to a motor mount board
- CD with application notes, production-ready motor control firmware source code and software tools including a motor control GUI
- Complimentary Keil® PK51 development software with unrestricted license (an approximate value of $2,500 USD)
- Power supply and USB cable
