Typical Applications
TMS320F28335QPGFAQ1 is suitable for 6 applications: Industrial Motor Drives, Solar Inverters and Digital Power, Electric Vehicles and Transportation, Digital Power Supplies and Servers, Sensing and Signal Processing, Automotive Body and Auxiliary Control.
Industrial Motor Drives
The TMS320F28335QPGFAQ1 excels in industrial motor drives because its 150 MHz C28x core with single-precision FPU executes field-oriented control (FOC) of PMSM and induction motors at high loop rates, while the 12-bit ADC captures phase currents for the fast inner current loop. Integrated PWM peripherals drive three-phase inverters with precise dead-time control. In a typical design the MCU senses current and voltage feedback, runs the control law every PWM cycle, and outputs inverter gate commands - achieving closed-loop bandwidth impossible with slower MCUs. The AEC-Q100 grade also covers harsh factory environments.
Recommended
Solar Inverters and Digital Power
In solar string and micro-inverters, the TMS320F28335QPGFAQ1 performs maximum power point tracking (MPPT), grid synchronization, and inverter control on one chip. Its FPU computes the MPPT algorithm and PLL-based grid-lock loops without fixed-point scaling overhead, and the EMIF can expand RAM for larger control structures. The 12-bit ADC samples DC bus and AC output voltages for feedforward control. The device's 18 PWM channels support interleaved converter topologies that reduce input ripple and increase efficiency, a direct benefit for photovoltaic energy harvest and grid-tie power conversion.
Recommended
Electric Vehicles and Transportation
For traction inverters, on-board chargers, and DC-DC converters in electric vehicles, the AEC-Q100-qualified TMS320F28335QPGFAQ1 provides the real-time control backbone. The 150 MHz C28x core with FPU runs motor control and battery-charging control laws concurrently with the 12-bit ADC providing current feedback at the PWM switching frequency. Its flash-based firmware supports OTA-capable field updates. Automotive qualification plus integration of control peripherals reduces external component count in space-constrained EV power electronics, while the EMIF supports additional memory for complex state machines and diagnostic logging.
Recommended
Digital Power Supplies and Servers
High-density server and telecom power supplies use the TMS320F28335QPGFAQ1 to implement digital LLC, phase-shifted full-bridge, and PFC control. The 150 MIPS core closes voltage loops at hundreds of kHz switching frequency, while the 12-bit ADC delivers the sampling precision needed for tight regulation (under 1% load transient deviation is achievable with proper compensation). The EMIF permits external memory for PMBus command tables and logging. Compared with dedicated analog controllers, the MCU adds programmability, adaptive tuning, and telemetry without adding a second control IC to the board.
Recommended
Sensing and Signal Processing
The TMS320F28335QPGFAQ1 functions as an intelligent sensing hub, using its DSP-class C28x core to run filtering, FFT, and estimation algorithms directly on digitized sensor data. The 12-bit ADC handles analog front-end sampling while the FPU executes fixed- or floating-point algorithms at 150 MIPS without external DSP support. Typical sensing systems interface the EMIF or GPIOs to external converters and use the on-chip communication peripherals for upstream reporting. This integration shortens the sensing-to-decision latency chain, making the part suitable for vibration monitoring, condition-based maintenance, and industrial instrumentation nodes.
Recommended
Automotive Body and Auxiliary Control
Beyond powertrain, the automotive-qualified TMS320F28335QPGFAQ1 serves auxiliary inverter, e-compressor, and electric power steering support control units. The AEC-Q100 qualification plus -40C-capable operation covers under-hood and chassis conditions. Its rich PWM and ADC resources drive BLDC auxiliary motors with sensorless algorithms executed on the FPU, while CAN communication peripherals (via external transceivers) link the node to the vehicle network. Using a single DSC for sensing, control, and actuation reduces BOM cost relative to MCU-plus-DSP two-chip solutions common in legacy designs.

Key Differentiators
- AEC-Q100 automotive qualification (vs TMS320F28335PGFA)
- Same die as commercial version enables dual-sourcing (vs TMS320F28335PGFA)
- Delfino-class memory plus EMIF (vs TMS320F28343-Q1)
- Stay in Delfino family vs redesign (vs TMS320F28346-Q1)
Design Notes
The TMS320F28335QPGFAQ1 requires dual-rail power sequencing: the 1.9V core rail and 3.3V I/O rail must follow TI datasheet sequencing requirements to avoid latch-up or boot failures. Use a supervisor with power-good monitoring (e.g., TPS38 series) and decouple each VDD pin with 0.1uF ceramics placed within 2 mm of the pin, plus bulk 10uF capacitance per rail.
The 176-LQFP (24x24 mm) PGF package has 0.5 mm pin pitch - use a solder-mask-defined pad pattern per TI's LQFP land-pattern guideline and inspect with AOI. Route the 12-bit ADC inputs away from ePWM and clock lines; use a dedicated analog ground island connected at a single point. The exposed internal power planes should keep core-rail impedance low at 150 MHz harmonic frequencies.
At 150 MHz, flash execution incurs wait-states - either accept the pipeline behavior or copy performance-critical code to on-chip RAM (code mentioned in TI's C2000 application notes). Verify JTAG header access for C2000 debugging early in layout. When substituting the TMS320F28335PTPQ automotive variant, confirm the HLQFP footprint differs from the PGF land pattern before release.
