Typical Applications
TMS320F28034PNT is suitable for 6 applications: Motor Control, Digital Power Supplies, Renewable Energy Inverters, Industrial Automation, Automotive Systems, Test and Measurement.
Motor Control
The TMS320F28034PNT excels in motor control applications such as field-oriented control (FOC) of PMSM and BLDC motors. Its 60 MHz C28x core and Control Law Accelerator (CLA) enable high-speed current loops, while the 12-bit ADC and high-resolution PWM modules provide precise voltage and current sensing. The CLA offloads time-critical control algorithms, allowing the CPU to handle commutation, communication, and system monitoring. This results in efficient, smooth motor operation with minimal torque ripple, making it ideal for industrial drives, robotics, and automotive power steering systems.
Recommended
Digital Power Supplies
In digital power conversion, the TMS320F28034PNT provides the computational power needed for advanced control topologies like LLC, phase-shifted full-bridge, and PFC. The high-resolution PWM modules (up to 150 ps) enable precise duty cycle control, while the fast 12-bit ADC captures voltage and current feedback with minimal latency. The CLA can execute the control loop in parallel with the CPU, reducing loop delay and improving transient response. This makes the MCU suitable for server power supplies, telecom rectifiers, and battery chargers, where efficiency and reliability are paramount.
Recommended
Renewable Energy Inverters
The TMS320F28034PNT is well-suited for solar and wind inverters, where it manages maximum power point tracking (MPPT) and grid synchronization. Its 60 MHz C28x core handles complex algorithms like perturb-and-observe MPPT, while the CLA accelerates the inner current control loop. The integrated ADC and comparators enable fast overcurrent protection, and the CAN interface facilitates communication with the grid or central controller. The wide operating temperature range and robust design ensure reliable operation in harsh outdoor environments.
Recommended
Industrial Automation
For industrial automation, the TMS320F28034PNT serves as a central controller for PLCs, robotic arms, and CNC machines. Its rich peripheral set includes multiple communication interfaces (SCI, SPI, I2C, CAN) for connecting to sensors, actuators, and HMI panels. The 12-bit ADC with 16 channels can monitor multiple analog signals, while the PWM outputs drive actuators and valves. The CLA can handle real-time tasks like position interpolation, ensuring precise motion control. The device's robustness and long-term availability make it a reliable choice for factory floor applications.
Recommended
Automotive Systems
Although the standard TMS320F28034PNT is not AEC-Q100 qualified, it is often used in automotive development and prototyping. For production, the Q1 variant is recommended. In automotive systems, the MCU can be used for engine control, transmission control, and electric power steering. Its high-performance C28x core and CLA enable real-time control of actuators and sensors, while the CAN interface supports vehicle networking. The device's small footprint and low power consumption are beneficial for space-constrained automotive modules.
Recommended
Test and Measurement
In test and measurement equipment, the TMS320F28034PNT provides precise timing and control for data acquisition systems, signal generators, and power analyzers. Its 12-bit ADC with 16 channels can sample multiple signals simultaneously, while the PWM modules generate precise trigger signals. The CLA can process data in real-time, enabling on-the-fly analysis and feedback. The device's deterministic execution and low latency make it suitable for applications requiring accurate timing, such as waveform generation and frequency measurement.

- Cost-effective balance (vs TMS320F28069UPNT)
Design Notes
The TMS320F28034PNT requires a 3.3V I/O supply and a 1.8V core supply. The 1.8V core can be generated internally from the 3.3V supply using an internal LDO, but for better efficiency and noise performance, an external 1.8V regulator is recommended. Place 100nF decoupling capacitors close to each VDD and VDDIO pin, and a 10uF bulk capacitor on the main supply rail.
For optimal ADC performance, separate analog and digital ground planes and connect them at a single point. Place the ADC reference decoupling capacitor (10uF) close to the VREFHI pin. Use a star topology for the analog supply to minimize noise coupling from digital switching.
Ensure the boot mode pins are configured correctly to avoid unexpected boot behavior. The TMS320F28034PNT has multiple boot modes (flash, SCI, SPI, etc.) selected by GPIO pins. Also, verify the clock source: if using an external crystal, ensure the load capacitors match the crystal specification. Incorrect clock configuration can cause the device to fail to start.
Compliance Information
