Texas Instruments has released its C2000 Piccolo series of MCUs that equip TI's Insta-SPIN field-oriented control (FOC) and motion control technologies on the read-only memory (ROM) of the chip, designed for a range of three-phase sensor-enabled or sensorless motor control applications.

The InstaSPIN technology enables designers to identify, tune the torque controller and efficiently control the motor in what TI says is just minutes, and without the use of any mechanical rotor sensors.

The C2000 Piccolo F2805x MCUs provide the power of the C28x core running at 60MHz with embedded memory for more storage, including up to 128KB Flash and up to 20KB SRAM. It features on-chip communication interfaces such as an SPI module, I2C bus, CAN 2.0 and three SCI/UART modules to improve connectivity for real-time communications.

To improve system efficiency and reduce bill of materials cost, the MCUs also integrate control peripherals including 12bit ADC, enhanced PWM channels with fault management, windowed analogue comparators with 10bit DACs, zero-pin oscillators, voltage regulator, programmable gain amplifiers and fixed-gain amplifiers.

The Piccolo MCUs with InstaSPIN are available, ranging from $4 to $12 per 1,000 units.
