TMS320F28031-Q1 Présentation
A C2000 MCU is a digital signal controller optimized for real-time control rather than general-purpose computing. Within the power-management hierarchy, C2000 devices form the digital control loop between power-conversion hardware and system software, sitting alongside families such as the TMS320F2803x Piccolo line and the larger F2837x Delfino parts. Their defining trait is deterministic, tightly closed control loops.
Key features include the 60 MHz C28x core, 64 KB flash with 10 KB SRAM, a 2 MSPS 12-bit ADC synchronized to the ePWM modules, and communication interfaces including CAN, SCI (UART), SPI, and I2C. Per the TMS320F2803x datasheet, the family couples the C28x core with the Control Law Accelerator (CLA) for parallel control mathematics in low pin-count packages.
Architecturally, the device uses a Harvard bus structure optimized for deterministic loop execution. The ADC, triggered by ePWM, enables the sample-to-output latency that current-loop control in motor drives and power inverters demands, while the CLA offloads control computations from the main CPU for lower loop jitter.
Typical applications include automotive motor control, PFC stages, LED headlights, battery management, body control modules, and HEV/EV auxiliary systems. The 60 MHz clock and 64 KB flash cover field-oriented control and LLC resonant-control code without over-provisioning.
Designers should ensure controlled supply sequencing, low-impedance grounding for ADC accuracy, and decoupling per TI layout guidelines; development uses Code Composer Studio with standard JTAG debug probes. This page adds verified pricing tiers, drop-in family alternatives, and practical design notes beyond the manufacturer datasheet.

Applications typiques
TMS320F28031-Q1 convient pour 6 applications: Automotive Motor Control, Digital Power and PFC Stages, HEV/EV Auxiliary Systems, Automotive LED Headlight Control, Battery Management Pack Control, Industrial Servo Drives and Inverters.
Automotive Motor Control
The TMS320F28031-Q1 fits automotive motor control because its 60 MHz C28x core plus CLA executes field-oriented control (FOC) with the deterministic latency that traction pumps, HVAC blowers, and radiator fans demand, while AEC-Q100 qualification and -40C to +125C operation survive under-hood conditions. The 2 MSPS 12-bit ADC, triggered directly by the ePWM modules, samples phase currents at the PWM midpoint, minimizing switching-noise error and enabling tight current-loop bandwidth. Firmware for sensorless observers or resolver decoding fits comfortably in 64 KB flash. Design consideration: keep the ADC reference ground star-connected to the shunt ground to preserve the 12-bit accuracy, and budget CPU headroom for the CAN stack alongside the control loop.

Digital Power and PFC Stages
In switched-mode power supplies and PFC front ends, the TMS320F28031-Q1 provides the digital control loop between the power stage and the system controller. The ePWM modules generate phase-shifted or complementary PWM with dead-band control, and the 2 MSPS ADC samples input/output voltage and inductor current fast enough for average-current-mode PFC at the frequencies typical of onboard chargers and telecom rectifiers. The CLA can run the fast inner current loop while the C28x CPU handles supervisory logic, protecting, and CAN communication. The 64 KB flash holds the control law plus protection state machines. Estimated benefit versus analog control: programmable nonlinear gain and feedforward that improve light-load efficiency without extra hardware.
Recommandé
HEV/EV Auxiliary Systems
Hybrid and electric-vehicle auxiliary loads - coolant pumps, oil pumps, e-compressors, and DC-DC converters - require AEC-Q100-qualified controllers with integrated CAN, and the TMS320F28031-Q1 delivers exactly that envelope in an 80-pin LQFP. Its 64 KB flash hosts sensorless motor control, functional protection, and CAN 2.0B communication simultaneously, while the CLA keeps the current loop deterministic at 60 MHz CPU speed. The 2 MSPS ADC supports shunt-based phase-current sensing and DC-link voltage monitoring with ePWM-synchronized sampling to reject switching noise. Designers should implement safe-state PWM trip logic using the ePWM trip-zone hardware so overcurrent events are handled in hardware, independent of software latency, a core C2000 safety pattern in EV auxiliaries.
Recommandé
Automotive LED Headlight Control
Adaptive LED headlight modules need a controller that combines precise current regulation, diagnostic reporting, and thermal derating - all in an AEC-Q100 device, which is the TMS320F28031-Q1's sweet spot. High-resolution ePWM outputs drive LED driver stages at fixed frequency with duty-cycle resolution fine enough for smooth intensity steps in adaptive driving beams, while the 12-bit, 2 MSPS ADC digitizes current-sense and thermistor channels for closed-loop current control and temperature derating. The CAN interface links the module to the body controller, and SCI/SPI support boot-time configuration of external drivers. The 64 KB flash holds the beam-pattern logic plus diagnostics. Keep ADC sampling synchronized away from PWM edges to avoid LED current-ripple artifacts in the measurement.

Battery Management Pack Control
As a pack-level controller, the TMS320F28031-Q1 orchestrates cell-monitoring front ends, contactors, pre-charge circuits, and isolation sensing, with its AEC-Q100 qualification meeting automotive quality gates. The 12-bit 2 MSPS ADC measures pack current via a shunt for coulomb counting support and fast overcurrent detection, while GPIO and ePWM outputs drive contactor and precharge sequencing with hardware trip protection. The CAN bus handles V2X and vehicle-network messaging; the 64 KB flash retains state-of-charge and fault logs across power cycles. Pairing the C2000 with a dedicated battery monitor IC offloads cell measurement, leaving the MCU headroom for protection algorithms. Use SPI at moderate clock rates with proper isolation layout when monitoring dV/dt-rich pack environments.
Recommandé
Industrial Servo Drives and Inverters
Although automotive-qualified, the TMS320F28031-Q1's control peripherals make it equally effective in industrial servo drives, solar micro-inverters, and UPS inverters, where the ePWM-to-ADC path is the defining feature. The 60 MHz C28x with CLA closes torque and speed loops deterministically; the 2 MSPS ADC samples phase currents for FOC or hysteresis control, and trip-zone hardware removes PWM output within one PWM cycle on fault detection - a hardware-level safety response software cannot match. 64 KB flash stores the control law, commutation tables, and Modbus/CAN communication stacks typical of compact drives. Estimated design margin: with an efficient interrupt scheme, the 60 MHz CPU sustains current-loop rates of 20 kHz or higher with supervisory tasks sharing the same silicon.

Notes de conception
Place 0.1 uF ceramic decoupling capacitors within 2 mm of each VDD/VDDIO pin pair, plus at least one bulk 10 uF capacitor per supply rail. Route the ADC reference and analog ground returns as a local analog island connected to the digital ground at a single point; the 2 MSPS ADC sampling capacitive kickback makes low-impedance reference decoupling essential. Follow the TI C2000 layout guidelines in the F2803x hardware design guide for the 80-pin LQFP thermal pad and fanout strategy.
Verify supply sequencing before first power-up: the F2803x core is derived from the 3.3 V rail via an internal regulator, and violating the datasheet ramp requirements can latch the device. Also confirm the pin multiplexing table - many LQFP-80 pins serve up to three functions (ePWM, eCAP, GPIO), and an incorrect GPAMUX/GPBMUX setting is the most common cause of a 'dead PWM' bug reported on the TI E2E forum for this family.
For ADC current-loop sampling, synchronize conversions to the center of the ePWM counter period (SOC trigger from ePWM) so that switching edges fall outside the sampling aperture; this measurably reduces current-sense ripple error versus free-running sampling. Keep shunt-sense traces Kelvin-connected and differential back to the ADC input pins, and add an RC anti-alias filter sized to the 2 MSPS rate (e.g. an estimated 1 kHz-100 kHz corner depending on loop bandwidth).
Estimated: at 60 MHz the C28x core draws on the order of tens of milliamps, so total board power is dominated by the driver stages, not the MCU. Still, size the 3.3 V rail with margin for simultaneous ADC operation and GPIO switching, and use the ePWM trip-zone hardware (one-shot) for overcurrent shutdown so protection response does not depend on firmware latency.
