Typical Applications
TMS320F28069PZT is suitable for 6 applications: Motor Control, Digital Power Supplies, Solar Inverters, Industrial Automation, Renewable Energy Systems, Test and Measurement.
Motor Control
The TMS320F28069PZT excels in motor control applications such as AC induction, BLDC, and PMSM drives. Its 90 MHz C28x core with FPU handles complex field-oriented control (FOC) algorithms, while the CLA offloads time-critical loops, freeing the CPU for other tasks. The integrated 12-bit ADC with up to 16 channels captures phase currents and rotor position, and the PWM modules generate precise switching signals. With a 10-ns cycle time, the device ensures deterministic response for high-speed motor control, achieving efficient torque and speed regulation.
Recommended
Digital Power Supplies
In digital power conversion, the TMS320F28069PZT provides the computational power for implementing digital control loops in buck, boost, and PFC converters. The FPU accelerates PID and filter calculations, while the CLA can execute the control loop in parallel with the main CPU, reducing latency. The high-resolution PWM modules (up to 150 ps) enable precise duty-cycle control, and the ADC samples voltage and current with 12-bit resolution. This results in high-efficiency power supplies with fast transient response and excellent load regulation.
Recommended
Solar Inverters
The TMS320F28069PZT is well-suited for solar inverter applications, where it manages maximum power point tracking (MPPT) and grid-tie control. Its 90 MHz processing speed and FPU handle complex algorithms like perturb-and-observe and incremental conductance. The CLA can run the MPPT loop independently, ensuring fast tracking under varying irradiance. The device's robust communication interfaces (CAN, SCI) enable monitoring and control, while the ADC and PWM modules interface with voltage/current sensors and inverter switches. This enables high-efficiency energy conversion and reliable grid synchronization.
Recommended
Industrial Automation
In industrial automation, the TMS320F28069PZT serves as a central controller for PLCs, robotics, and process control systems. Its 54 GPIO pins and multiple serial interfaces (SCI, SPI, I2C, CAN) allow connection to sensors, actuators, and fieldbuses. The 12-bit ADC with 16 channels monitors analog signals, while the PWM outputs drive actuators. The device's real-time capabilities ensure deterministic response to events, and the low-power modes help reduce energy consumption in always-on systems. The CLA can handle fast control loops, leaving the CPU for higher-level tasks.
Recommended
Renewable Energy Systems
The TMS320F28069PZT is used in renewable energy systems such as wind turbines and battery energy storage systems. Its high-speed processing and FPU enable advanced control algorithms for power conversion and grid integration. The CLA can handle real-time tasks like phase-locked loops (PLL) for grid synchronization, while the CPU manages system monitoring and communication. The device's wide operating temperature range (-40C to +105C) suits harsh outdoor environments. With integrated protection features and robust peripherals, it ensures reliable operation in demanding energy applications.
Recommended
Test and Measurement
In test and measurement equipment, the TMS320F28069PZT provides the processing power for data acquisition, signal analysis, and control. Its 12-bit ADC with 16 channels captures multiple analog signals simultaneously, while the DMA controller transfers data without CPU intervention, enabling high-throughput sampling. The FPU accelerates digital signal processing algorithms like FFT and filtering. The device's multiple timers and PWM outputs can generate precise trigger signals. With its real-time capabilities, it is ideal for oscilloscopes, data loggers, and automated test systems.

- Automotive-grade option (vs TMS320F28069MPZT)
Design Notes
The TMS320F28069PZT requires a 1.8V core supply and a 3.3V I/O supply. Use separate LDOs or DC-DC converters for each rail, and place decoupling capacitors (0.1uF and 1uF) close to each VDD and VDDIO pin. Ensure the core supply ramps up before or simultaneously with the I/O supply to avoid latch-up. The device has no power sequencing requirement, simplifying design, but proper decoupling is critical for stable operation.
For the 100-LQFP package, use a 4-layer PCB with dedicated power and ground planes. Place the crystal oscillator and its load capacitors close to the X1/X2 pins, and keep the ADC input traces short and shielded to minimize noise. Route high-speed PWM signals away from analog inputs to reduce crosstalk. Use a solid ground plane under the device to improve thermal performance and signal integrity.
A common mistake is neglecting the ADC reference decoupling. The ADC requires a clean reference voltage; place a 10uF and 0.1uF capacitor near the VREFHI pin. Also, ensure the JTAG pins are properly pulled up or down for reliable debugging. When using the internal oscillator, be aware of its accuracy; for applications requiring precise timing, use an external crystal. Finally, do not exceed the absolute maximum ratings on any pin to avoid damage.
