TMS320F28035PNT Descripción general
A microcontroller (MCU) is a compact integrated circuit combining a processor core, memory, and programmable peripherals on a single chip. The C2000 family is a specialized class of MCUs optimized for real-time control, pairing the C28x DSP-class core with high-resolution PWM, fast 12-bit ADCs, and on-chip comparators. Taxonomically: C2000 MCU -> real-time microcontroller -> digital signal controller -> embedded processor -> semiconductor.
Key features include a 60 MHz C28x CPU with an independent Control Law Accelerator (CLA) also running at 60 MHz, effectively doubling throughput for time-critical control loops; 128KB flash with 20KB SRAM; up to 45 GPIO; a 12-bit ADC with up to 16 channels; on-chip comparators; and high-resolution ePWM with 150 ps resolution. Communication peripherals include SCI (UART), SPI, I2C, CAN, and LIN.
Architecturally, the device uses a modified Harvard architecture with a unified memory map, operating from a single 3.3V supply with an internal voltage regulator. The CLA executes control algorithms concurrently with the main C28x CPU, cutting control-loop latency in digital power and motor drive systems where switching frequencies exceed 100 kHz. The device is code-compatible with previous C28x generations, easing migration from older F280x designs.
Typical applications include field-oriented control (FOC) of PMSM and BLDC motors, solar inverters with MPPT, digital power supplies (LLC, active clamp, totem-pole PFC), HEV/EV onboard chargers and traction inverters, and battery management systems. The high analog integration reduces external component count in compact power stages.
Design tip: decouple the 3.3V supply with 100 nF and 10 uF capacitors close to the VDD pins, and route the ADC reference away from PWM switching noise for best conversion accuracy. Use the ePWM trip-zone inputs for hardware overcurrent protection.

Aplicaciones típicas
TMS320F28035PNT es adecuado para 6 aplicacións: Industrial Motor Drives and Servo Control, Solar Inverters with MPPT, Digital Power Conversion (LLC, Active Clamp, PFC), HEV/EV Onboard Chargers and Traction Inverters, Battery Management Systems (BMS), Renewable Energy and Distributed Power Systems.
Industrial Motor Drives and Servo Control
The TMS320F28035PNT fits industrial motor drives because its 150 ps high-resolution ePWM enables precise dead-time and switching control for field-oriented control (FOC) of PMSM and BLDC motors, while the 12-bit ADC with up to 16 channels samples phase currents and DC bus voltage synchronously with the PWM carrier. The independent 60 MHz CLA runs the current control loop concurrently with the 60 MHz C28x CPU handling supervision and communication, keeping loop latency low at switching frequencies above 100 kHz typical of servo drives. On-chip comparators with trip-zone inputs shut down PWM outputs in hardware within nanoseconds on overcurrent events, protecting power stages without CPU intervention.
Recomendado
Solar Inverters with MPPT
In solar micro-inverters and string inverters, the TMS320F28035PNT performs maximum power point tracking (MPPT), DC-DC boost control, and grid-synchronized DC-AC inversion on one chip. Its 128KB flash accommodates PLL grid synchronization, MPPT algorithms, and safety firmware, while the 60 MHz C28x plus 60 MHz CLA split the boost converter loop (CLA) from the inverter loop and housekeeping tasks (CPU). The 150 ps HRPWM resolution supports high-frequency LLC and phase-shifted full-bridge stages, and the 12-bit ADC monitors panel voltage/current and grid waveforms for anti-islanding and grid-code compliance in renewable energy installations.
Recomendado
Digital Power Conversion (LLC, Active Clamp, PFC)
For digital power supplies such as LLC resonant converters, active-clamp forwards, and totem-pole or boost PFC stages, the TMS320F28035PNT replaces fixed-function controllers with a programmable solution. Its ePWM modules support frequency and phase modulation with 150 ps effective resolution for precise resonant control, while adaptive dead-time insertion maximizes efficiency across load ranges. The CLA executes the fast voltage/current loops at 60 MHz, freeing the C28x CPU for PMBus/I2C telemetry, fault logging, and housekeeping. Digital soft-start, burst mode, and protection profiles are all implemented in firmware, cutting BOM cost versus analog control with a 3.3V single-supply design.
Recomendado
HEV/EV Onboard Chargers and Traction Inverters
In electric vehicle systems, the TMS320F28035PNT controls power-factor-corrected AC-DC front ends and isolated DC-DC stages of onboard chargers, and supports auxiliary inverter functions in traction systems. Its -40C to +105C operating range suits under-hood and battery-adjacent environments, and the 12-bit ADC samples isolated current and voltage feedbacks (via AMC1311-class isolators) for control and diagnostic compliance. Note that for safety-critical traction functions requiring AEC-Q100 qualification, the pin-compatible TMS320F28035PNQ or TMS320F28035-Q1 automotive variants should be specified instead of the industrial-grade PNT.
Recomendado
Battery Management Systems (BMS)
The TMS320F28035PNT serves as the pack-level controller in battery management systems, coordinating cell monitoring front-ends over SPI or I2C, balancing decisions, and pack current/voltage supervision. Its 128KB flash stores state-of-charge and state-of-health algorithms with room for data logging, while the 12-bit ADC provides redundant pack-level measurements independent of the cell-monitoring AFE for functional safety cross-checks. The CLA can run fast overcurrent/overvoltage protection loops concurrently with the C28x CPU executing SOC estimation. CAN and LIN interfaces connect the BMS to vehicle or inverter controllers, and the -40C to +105C range covers automotive and industrial battery environments.
Recomendado
Renewable Energy and Distributed Power Systems
Beyond inverters, the TMS320F28035PNT controls wind micro-turbine converters, fuel-cell DC-DC stages, energy storage converters (PCS), and bidirectional AC/DC charging modules in distributed renewable energy systems. Its combination of a real-time 60 MHz C28x core, deterministic 150 ps PWM resolution, and hardware comparators delivers the fast fault response (trip-zone shutdown in hardware) that grid-tied power conversion demands. Dual communication stacks (CAN, SCI, SPI, I2C) let one MCU bridge power conversion control with supervisory SCADA or energy-management links, and the code-compatible C2000 ecosystem provides certified software libraries for grid-support functions such as reactive power injection.

Notas de diseño
The TMS320F28035PNT operates from a single 3.3V supply with an internal VREG supplying the core. Decouple each VDD pin with 100 nF ceramic capacitors placed within 2 mm of the pin, and add a 10 uF bulk capacitor near the device. Tie VDDIO to the same 3.3V rail. Avoid powering flash programming from supplies that droop during inrush, as brownouts can corrupt flash; consider TI's TPS3823-class supervisor for reset integrity.
Route ADC inputs away from ePWM switching traces; the 12-bit ADC is effective but sensitive to switching-induced crosstalk in motor drive layouts. Use a dedicated low-noise analog 3.3V feed and place an RC filter (e.g., 100 ohm / 1 nF) at each ADC input within source impedance limits. Star-ground the analog section or use a solid ground plane with analog routing discipline. Keep the crystal or external oscillator traces short and guarded.
Do not substitute the F28034 or F28032 without verifying flash fit - the 128KB flash of the F28035 is the largest in the F2803x family, and firmware near capacity will not run on smaller-memory siblings. Also remember the PNT is industrial grade: automotive programs must use the PNQ/Q1 variant for AEC-Q100 qualification. When migrating to newer C2000 generations (F28002x, F28001x), budget for recompilation and peripheral driver changes - they are not pin-to-pin drops.
