TMS320F28035-Q1 Descripción general
A microcontroller (MCU) is a compact integrated circuit that combines a processor core, memory, and programmable input/output peripherals on a single chip. The C2000 family is a specialized line of MCUs optimized for real-time control, with a digital signal processor (DSP)-like architecture that excels in mathematical computations required for closed-loop control algorithms. The TMS320F28035-Q1 sits within the C2000 Piccolo series, which balances cost and performance for automotive and industrial applications.
Key features include a 32-bit C28x CPU with a 60 MHz clock, 128 KB of flash memory, 20 KB of SRAM, and a Control Law Accelerator (CLA) that offloads math-intensive tasks from the main CPU. It also includes a 12-bit ADC with up to 16 channels, multiple PWM modules, and communication interfaces such as SPI, SCI (UART), and I2C. The device operates over a wide temperature range of -40C to +125C, making it suitable for harsh automotive environments.
The architecture integrates a Harvard bus structure for efficient real-time signal processing. The CLA is a parallel processor that can execute control algorithms independently, reducing CPU load and enabling faster loop rates. The device also features a memory protection unit and a watchdog timer for enhanced reliability.
Typical applications include automotive motor control (e.g., pumps, fans, and power steering), DC-DC converters, battery management systems, and industrial drives. Its automotive qualification (AEC-Q100) ensures compliance with stringent quality and reliability standards.
When designing with this MCU, ensure proper decoupling of the power supply pins and a clean ground plane to minimize noise. The CLA can be used to offload time-critical control loops, but careful consideration of memory partitioning is required to avoid conflicts.

Aplicaciones típicas
TMS320F28035-Q1 es adecuado para 6 aplicacións: Automotive Motor Control, DC-DC Power Conversion, Battery Management Systems, Industrial Motor Drives, Solar Inverters and Digital Power, Automotive Sensing and Signal Processing.
Automotive Motor Control
The TMS320F28035-Q1 drives pumps, fans, and electric power steering motors with its 60 MHz C28x core and independent CLA running field-oriented control loops. The ePWM modules produce complementary outputs with hardware dead-band, while the 12-bit ADC samples phase currents for closed-loop torque control. Its AEC-Q100 qualification and -40C to +125C range meet automotive under-hood requirements, and the CLA enables loop rates that a general-purpose MCU could not sustain alone.
Recomendado
DC-DC Power Conversion
In automotive DC-DC converters, the TMS320F28035-Q1 implements digital control of buck, boost, and LLC topologies. The CLA executes voltage and current compensation loops independently while the main CPU handles housekeeping, state machines, and fault management. High-resolution PWM supports frequency modulation for EMI optimization, and the 12-bit ADC monitors input/output voltage and temperature. Digital control enables adaptive algorithms and diagnostics beyond what analog controllers offer.
Recomendado
Battery Management Systems
The TMS320F28035-Q1 serves as the BMS master controller in EV and HEV battery packs, coordinating cell monitoring front-ends via SPI or UART while running state-of-charge and state-of-health algorithms on the CLA. Its watchdog timer and memory protection unit support functional-safety-oriented designs. CAN (eCAN) connectivity interfaces the BMS with vehicle ECUs, and the wide -40C to +125C operating range suits underbody pack environments.
Recomendado
Industrial Motor Drives
The same control peripherals that serve automotive applications make the TMS320F28035-Q1 (or its industrial TMS320F28035PAGT sibling) effective in industrial drives for BLDC, PMSM, and AC induction motors. The C28x core is code-compatible with previous C28x devices, protecting software investment. Integrated PWM, ADC, and comparators support overcurrent trip zones in hardware, enabling cycle-level fault shutdown without CPU intervention - a key reliability advantage in high-power drives.
Recomendado
Solar Inverters and Digital Power
In solar micro-inverters and string optimizers, the TMS320F28035-Q1 executes MPPT algorithms on the main CPU while the CLA runs fast current loops for the power stage. Its 60 MHz performance handles multiple simultaneous control loops, and high ADC throughput captures grid current waveforms for active anti-islanding and grid-tie compliance. The F2803x family was explicitly designed by TI for solar inverter and digital power applications per the datasheet.
Recomendado
Automotive Sensing and Signal Processing
Beyond actuation, the TMS320F28035-Q1 excels in sensing nodes that require local signal processing - position sensors, current monitoring, and diagnostic modules. The 12-bit ADC with up to 16 channels multiplexes multiple sensor inputs, and the DSP-like C28x architecture performs filtering and FFT analysis on-chip. Results are reported over CAN or UART, reducing wiring harness complexity by processing data at the sensor rather than in a central ECU.

Notas de diseño
Provide a solid ground plane and place 100 nF ceramic decoupling capacitors at every VDD/VDDIO pin pair, as close to the pins as possible. The 12-bit ADC reference should be filtered and routed away from ePWM switching noise; use Kelvin grounding for current-sense signals feeding ADC inputs to preserve accuracy in motor control loops.
When migrating firmware between F2803x family members (e.g., F28035 to F28031), confirm flash size fits and that CLA-dependent code is removed if the target lacks the CLA. Q1 and non-Q1 parts share die but differ in qualification - never substitute industrial grade for automotive builds without requalification.
The device requires a core supply and I/O supply rails; use the TI-recommended power sequencing and monitor with the integrated brown-out/reset features. Refer to TI C2000 hardware design guides (SPRABV4 series) for reference power trees using TPS7A-class LDOs feeding the 1.8V core.
The CLA runs parallel control code while the CPU accesses the same SRAM - partition CLA vs CPU memory regions in the linker command file to avoid contention stalls and nondeterministic loop timing in high-speed control applications.
