TMS320F28075PTPT Descripción general
A C2000 Piccolo microcontroller is a 32-bit MCU family from Texas Instruments optimized for digital control of power, motor, and signal-conversion systems. The C28x CPU combines a single-cycle MAC DSP engine with a Harvard-style memory bus, while the FPU and TMU extend the architecture to IEEE-754 floating-point math and dedicated sine/cosine/arctangent acceleration used in field-oriented motor control. The Piccolo sub-family sits below the Delfino sub-family in the C2000 taxonomy (C2000 > Piccolo > C28x > DSP/MCU), balancing cost, integration, and real-time performance for industrial and renewable-energy applications.
Key features include 120 MHz CPU clock with single-cycle 32-bit MAC, 512 KB single-bank flash with ECC, configurable logic block (CLB) for custom glue logic, 12-bit and 16-bit ADC subsystems, sigma-delta filter (SDFM) interface for isolated current sensing, up to 20 PWM channels with high-resolution capability, control-law accelerator (CLA) for offloading the main CPU, and a CAN 2.0B / SPI / I2C / UART / LIN peripheral set. The on-chip SDFM accepts isolated sigma-delta bit-streams from TI's AMC-family current shunt monitors, enabling direct shunt-based phase-current measurement without an external modulator.
The architecture separates compute from control: the FPU/TMU-accelerated C28x handles state-machine and high-level control, while the CLA executes time-critical inner loops such as current sampling and PWM update at zero CPU overhead. The integrated SDFM, HRPWM, and comparator subsystems eliminate many external components required in discrete DSP + FPGA solutions.
Typical applications include solar micro-inverters and string inverters, servo and AC induction motor drives, on-board EV chargers, digital power supplies (PFC + LLC), industrial PLCs and process controllers, and wireless charging transmitters. The functional-safety documentation (FMEDA, safety manual) supports IEC 61508 SIL-2 and ISO 26262 ASIL-B target designs when the part is used with the corresponding TI safety software package.
Designers should note that pin-compatible C2000 supersets (F2837xS, F2837xD) can drop in for the F28075PTPT in the 176-HLQFP footprint, allowing upward migration to higher flash/CPU resources on identical PCB layouts. The 176-HLQFP powerPAD exposed pad must be soldered to a sufficiently large copper pour to keep junction temperature within the -40C to +105C operating range under full peripheral load.
This page synthesizes distributor stock, drop-in pin-compatible variants in the same 176-HLQFP footprint, and field application notes that complement the TI datasheet.

Aplicaciones típicas
TMS320F28075PTPT es adecuado para 6 aplicacións: Solar Micro-Inverter and String Inverter Control, Industrial Servo and AC Motor Drives, On-Board EV Charger (OBC) and EV Charging Stations, Digital Power Supply (PFC + LLC / Phase-Shifted Full-Bridge), Wireless Charging Transmitter (Qi / Proprietary), Industrial PLC and Process Controller.
Solar Micro-Inverter and String Inverter Control
The TMS320F28075PTPT's 120 MHz C28x with FPU and TMU executes MPPT, anti-islanding, and grid-synchronization loops at sub-millisecond latency. The integrated HRPWM channels deliver 200 ps duty-cycle resolution for the DC-AC H-bridge, while the SDFM accepts isolated current bit-streams from TI AMC1306 modulators, eliminating the need for external ADCs. Compared with a Delfino F28335, the F28075PTPT reduces BOM cost by integrating the SDFM and CLB and supports IEC 62109-1 functional-safety compliance. A complete micro-inverter firmware stack (MPPT + grid-tie) fits within the 512 KB flash.
Recomendado
Industrial Servo and AC Motor Drives
For three-phase servo and induction motor drives, the TMS320F28075PTPT delivers field-oriented control (FOC) at up to 30 kHz current-loop bandwidth. The TMU accelerates Park/Inverse-Park and sin/cos transforms, freeing the C28x to handle state-machine and CANopen/EtherCAT communication. The CLA offloads the SVM and current-sampling tasks, leaving zero CPU overhead for the outer velocity loop. The 176-HLQFP exposes the maximum PWM/ADC pinout, supporting triple-shunt-up sensor feedback and incremental encoder interfaces.
Recomendado
On-Board EV Charger (OBC) and EV Charging Stations
The TMS320F28075PTPT supports both PFC and LLC stages in a single MCU for 3.3 kW-7.4 kW on-board chargers. The high-resolution PWM aligns the interleaved PFC phases, while the SDFM captures isolated current across the LLC transformer secondary for closed-loop regulation. TI's functional-safety collateral (FMEDA, safety manual) supports ISO 26262 ASIL-B target designs, a regulatory requirement for automotive traction and charging ECUs. Compared to a dual-MCU PFC+LLC architecture, the F28075PTPT BOM reduces part count by one full MCU.
Recomendado
Digital Power Supply (PFC + LLC / Phase-Shifted Full-Bridge)
Server and telecom PSUs use the TMS320F28075PTPT to implement digital PFC followed by an LLC or phase-shifted full-bridge stage. The 120 MHz C28x with FPU handles complex digital-compensator math (type-3, notch, adaptive gain) per switching cycle. The CLB configures hardware fault-protection logic (OCP, OVP) with sub-microsecond response, faster than CPU-based interrupts. Compared with an analog UCC25640 LLC controller, the F28075PTPT adds adaptive burst-mode and adaptive dead-time for higher light-load efficiency.
Recomendado
Wireless Charging Transmitter (Qi / Proprietary)
For automotive and consumer wireless charging pads, the TMS320F28075PTPT generates the precise 85-205 kHz Qi ASK/FSK modulated H-bridge drive and implements foreign-object detection (FOD) via Q-factor and power-loss measurements. The TMU accelerates the resonant-tank math at each PWM cycle, while the SDFM reads isolated resonant current and coil-voltage sense signals. The functional-safety collateral simplifies automotive Qi certification for in-cabin charging systems.
Recomendado
Industrial PLC and Process Controller
The TMS320F28075PTPT integrates analog and digital I/O for high-speed industrial PLC and process controller applications. With on-chip ADC, SDFM, CAN, SPI, I2C, and UART, it can replace a discrete DSP + FPGA solution in a single MCU. The CLA offloads high-rate encoder-counter and PWM-timestamp tasks, while the CLB implements custom deterministic logic for safety interlocks. TI provides certified IEC 61508 SIL-2 collateral, allowing the F28075PTPT to be used directly in safety-rated PLC backplanes.

Notas de diseño
Estimated: at 1.2V core / 3.3V I/O with all peripherals active, the F28075PTPT typically draws 200-300 mA. With a 176-HLQFP powerPAD theta_JA of approximately 25 C/W on a 4-layer JEDEC test board, junction temperature rise is 5-7C above ambient at full load. For continuous 105C ambient operation, solder the exposed powerPAD to at least 2 square inches of copper pour on top and bottom layers tied by thermal vias. This is critical for motor-drive designs with high PWM duty cycles.
Place the 1.2V core decoupling capacitors (1x 10 uF + 4x 100 nF per VDD rail) within 5 mm of their respective pins. The 3.3V I/O decoupling follows the same rule, with one 10 uF bulk per power quadrant. Keep the SDFM bit-stream traces short and routed as 100 ohm differential pairs away from PWM and ADC switching nodes; SDFM jitter directly degrades current-sense accuracy.
Do not assume that F2837x firmware binary is drop-in compatible with F28075; the peripheral instances, CLA task table offsets, and GPIO mux mappings differ between the two families even when they share the 176-HLQFP footprint. Re-validate boot-ROM configuration, DCAN bit-timing registers, and the ePWM shadow-to-active load timing. Also confirm the JTAG TCK pin has a 10 kohm pull-up to 3.3V per TI datasheet, or scan-chain lock-up may occur at POR.
