Typical Applications
TMS320F28343-Q1 is suitable for 6 applications: Industrial Motor Drives, Solar Inverters, Electric Vehicles (EV) Powertrain Control, Sensing and Signal Processing, Digital Power Supplies, Automotive Body and Lighting.
Industrial Motor Drives
The TMS320F28343-Q1, as a C2000 Delfino real-time MCU, is designed for closed-loop motor control. With its C28x core, it can execute complex field-oriented control algorithms at high speed. While the exact clock frequency is not verified, the Delfino family typically runs at 150 MHz, enabling fast PWM updates and precise current regulation. It supports multiple PWM outputs and high-resolution ADCs, making it suitable for servo drives, variable frequency drives, and pump control. Designers must ensure the ADC and PWM timings are properly configured to achieve the desired torque and speed control.
Recommended
Solar Inverters
In solar inverter applications, the TMS320F28343-Q1 can perform maximum power point tracking (MPPT) and grid synchronization. The C2000 family provides rich digital control peripherals for managing power electronics. The real-time performance of the C28x core allows fast loop control of DC-DC converters and inverters. The device's PWM modules are suitable for generating high-frequency switching signals. For a solar inverter, the ADC must sample phase currents and voltages with high accuracy. Although specific ADC resolution is not verified, typical Delfino parts offer 12-bit ADCs. Converters benefit from the DSP-like arithmetic for efficient MPPT algorithms.

Electric Vehicles (EV) Powertrain Control
TMS320F28343-Q1 is an automotive-grade MCU suitable for EV powertrain control, including inverter control for traction motors and DC-DC converters. The Q1 suffix indicates AEC-Q100 qualification, though the exact qualification is not verified. Its C28x core is optimized for real-time control, ensuring stable operation under extreme temperatures and vibration. The device can manage multiple control loops simultaneously, such as torque control and battery management. For EV applications, functional safety is paramount. TI's C2000 family supports safety features like Error Correction Code (ECC) on memory and hardware fault protections. The pinout must be confirmed to integrate with gate drivers and sensors.
Recommended
Sensing and Signal Processing
The TMS320F28343-Q1 is capable of handling high-speed sensing and signal processing tasks, such as rotor position estimation and vibration monitoring. Its C28x DSP core provides MAC operations that accelerate digital filters. In a typical application, the MCU samples analog signals from encoders or magnetic sensors via its ADCs and processes them to derive position or speed. The device's trigonometric math unit (TMU) in later Delfino models speeds up sine/cosine calculations, but this feature is not verified for this part. Engineers should confirm whether the TMU is available. For communication, the MCU supports standard interfaces like SPI, I2C, and CAN for reporting to a host controller.

Digital Power Supplies
In digital power supply designs, the TMS320F28343-Q1 can be used as a controller for LLC resonant converters or buck-boost converters. The C2000 family offers dedicated PWM modules with dead-time support, enabling efficient switching. The MCU's high-speed ADC allows precise monitoring of output voltage and current, facilitating dynamic response. Although the exact clock speed is unknown, Delfino parts typically provide sufficient performance for loop rates above 10 kHz. Designers must carefully implement voltage compensation to ensure stability. The MCU also supports multiple feedback loops, making it suitable for multi-phase power supplies. Hardware protections such as overcurrent and overvoltage can be implemented using on-chip comparators.
Recommended
Automotive Body and Lighting
The TMS320F28343-Q1 is suitable for automotive body and lighting applications, such as headlamp control and window lifts. Its real-time capabilities ensure smooth operation of actuators and LED drivers. The MCU integrates timers and PWM outputs that can generate dimming signals for LED lamps. As a Q1 variant, it is designed to withstand harsh automotive environments. The device's communication interfaces, like CAN, allow it to interact with vehicle networks. For lighting, precise PWM frequencies (e.g., 20 kHz) avoid visible flicker. Although the exact PWM resolution is not verified, C2000 parts typically offer 16-bit PWM counters. The MCU can also monitor fault conditions and enter safe states.

- Potential for high performance (vs TMS320F28334-Q1)
Design Notes
Ensure a stable power supply: use a 1.9V core and 3.3V I/O rails with decoupling capacitors. Place 0.1uF and 1uF capacitors close to each power pin. If the exact voltage requirements are unknown, confirm from the datasheet before layout.
The Delfino MCU can dissipate significant power, especially at 150 MHz. Provide adequate copper pour and, if necessary, a heatsink. For automotive temperatures, derate the clock speed and observe junction temperature limits. Verify the package thermal resistance from the datasheet.
Do not assume pin compatibility with other C2000 parts without a verified datasheet. The TMS320F28343-Q1 may have different pin functions. Also, ensure the flash programming voltage is correctly applied. Use the TI Uniflash tool for programming.
Compliance Information
The -Q1 suffix implies automotive qualification, but specific values are not verified. RoHS and other compliance details require confirmation from official documentation.
