Typical Applications
TMS320F28032 is suitable for 6 applications: Digital Power Conversion (PFC, LLC, PSFB), BLDC and PMSM Motor Drives, Solar Micro-Inverters and MPPT, Industrial Automation and Control Cards, Automotive Real-Time Control, Uninterruptible Power Supplies and Energy Storage.
Digital Power Conversion (PFC, LLC, PSFB)
The TMS320F28032 fits digitally controlled AC/DC and DC/DC power stages because its 60 MHz C28x core, atomic operations and fast interrupt response keep voltage/current loop ISR entry jitter extremely low - the key determinant of achievable loop bandwidth. The 4.6 MSPS 12-bit ADC samples inductor or phase current at up to 4.6 million conversions per second, supporting cycle-by-cycle peak current mode at 100 kHz-plus switching frequencies. High-resolution ePWM peripherals typical of the F2803x family implement phase-shifted full-bridge, LLC and boost-PFC topologies with sub-nanosecond PWM edge resolution. Placed as the single control IC, it replaces analog compensators and adds programmable protection, soft-start and telemetry, at the cost of firmware development effort versus a purely analog controller.
Recommended
BLDC and PMSM Motor Drives
For brushless DC and permanent-magnet synchronous motor control, the TMS320F28032 provides the deterministic timing that field-oriented control (FOC) demands: single-cycle 32x32 MAC operations execute Clarke/Park transforms and PI compensators within one 16.67 ns-class control cycle budget, while the 4.6 MSPS ADC captures two or three phase currents nearly simultaneously. The F2803x ePWM modules generate complementary center-aligned PWM with hardware dead-band and trip-zone protection for inverter bridges. In trapezoidal (six-step) schemes, capture peripherals handle hall-sensor commutation. The main trade-off is that 64 KB flash suits fixed-point FOC stacks, but sensorless-observer firmware with floating-point-intensive algorithms may need the pin-compatible TMS320F28035 with its CLA coprocessor.
Recommended
Solar Micro-Inverters and MPPT
Grid-tied solar micro-inverters and MPPT stages use the TMS320F28032 because it can run panel maximum-power-point tracking, DC/DC boost control and grid-synchronization (PLL) routines concurrently at 60 MHz with deterministic interrupt scheduling. The 4.6 MSPS ADC digitizes panel voltage/current and grid voltage feedback fast enough for anti-islanding detection and current-harmonic shaping. Harvard bus architecture with unified memory supports the nested ISR structure typical of inverter firmware. The 64 KB flash accommodates MPPT plus inverter control in fixed-point C. Designers should reserve flash headroom for certification firmware (grid codes) or step up to the pin-compatible 128 KB TMS320F28035PNT without PCB changes.
Recommended
Industrial Automation and Control Cards
In factory automation, the TMS320F28032 serves as the real-time control element in PLC I/O cards, robotics joint controllers and actuator drivers where closed-loop response time matters more than general-purpose throughput. Its 16.67 ns cycle time, atomic read-modify-write operations and fast interrupt processing give deterministic sensor-to-PWM latency, while the 4.6 MSPS ADC handles encoder-interleaved current and position feedback sampling. The 64-pin TQFP (10x10 mm) footprint with surface mounting integrates into dense industrial PCBs, and the active lifecycle plus AEC-Q100 TMS320F28032-Q1 variant give procurement teams a qualification path from industrial to vehicular deployments using identical firmware. JTAG real-time debugging via Code Composer Studio lets engineers watch running control variables without halting the loop.
Recommended
Automotive Real-Time Control
Through the AEC-Q100 qualified TMS320F28032-Q1, this device addresses automotive subsystems such as electric power steering ancillaries, cooling-fan inverters, pumps and on-board charger control stages. The identical 60 MHz C28x core, 64 KB flash and 4.6 MSPS ADC mean firmware developed on the commercial part ports directly, while the -Q1 qualification satisfies automotive component quality requirements for temperature and reliability. The 4.6 MSPS ADC supports current sensing in 12 V auxiliary inverter bridges, and high-resolution PWM meets the tight dead-time control demanded by audible-noise-sensitive automotive actuators. Teams should verify the specific temperature grade (per the Q1 datasheet) against their under-hood placement, and order the -Q1 suffix exclusively for automotive production programs.
Recommended
Uninterruptible Power Supplies and Energy Storage
UPS and battery-energy-storage systems embed the TMS320F28032 as the inverter and battery-converter controller: the 60 MHz C28x core executes the multiple nested loops (battery current, bus voltage, grid current) with deterministic priorities, and the 4.6 MSPS ADC provides the oversampling headroom used for RMS metering and waveform quality checks. The F2803x ePWM architecture supports interleaved bidirectional converter legs needed for charge/discharge transitions, with trip-zone hardware for fast fault gating independent of CPU response. The 64 KB flash fits fixed-point control plus state-machine logic; complex harmonic-compensation firmware may favor the pin-compatible 128 KB TMS320F28035PNT. Analog design effort concentrates on ADC front-end scaling, since the on-chip converter handles both fast current loops and slower supervisory channels.

Key Differentiators
- Deterministic real-time control at lowest F2803x-tier cost (vs TMS320F28035PNT)
- Pin-compatible memory upgrade path (vs TMS320F28034PNT)
- Automotive qualification option on identical silicon (vs TMS320F28032-Q1)
Design Notes
Flash budget is the most common F28032 design pitfall: 64 KB (32K x 16) fits fixed-point control loops comfortably but can overflow once sensorless observers, floating-point emulation, and communication stacks accumulate. Compile early with the free C2000 CGT compiler and inspect the .map file; if text plus const data approaches the limit, migrate to the pin-compatible TMS320F28034PNT or TMS320F28035PNT (128 KB) with zero PCB change. Also confirm linker CMD files match the F28032 memory map when reusing F2803x example projects.
Keep the ADC front-end within the datasheet input range: the 4.6 MSPS sampling relies on low source impedance and adequate sample-hold settling, so series resistors and any op-amp drivers (e.g., OPA2350-class) should present low impedance at the selected sample window. For current sensing in digital power designs, filter shunt signals close to the pin and use the F2803x ADC calibration routine at boot. Decouple VDD/VDDIO per the TMS320F2803x datasheet power-supply section with local 0.1 uF ceramics at each supply pin pair.
Use the exposed layout conventions of the 64-TQFP (10x10 mm, 0.5 mm pitch): route the ePWM outputs to gate drivers with matched lengths for inverter legs, keep JTAG traces short and add series termination on TCK to avoid boundary-scan failures with XDS100-class emulators. Place the crystal/oscillator close to XCLKIN/X1-X2 pins with guard ground. Reserve programming access: TI recommends leaving JTAG header footprint on production boards since Code Composer Studio real-time mode is the primary debug path for running control loops.
Compliance Information
Compliance status must be confirmed on the TI product page (ti.com quality data) for the specific ordering suffix. The TMS320F28032-Q1 variant carries AEC-Q100 qualification for automotive use.
