TMS320F280040C-Q1 Présentation
What is a real-time microcontroller? A real-time MCU is a specialized microcontroller optimized for deterministic, low-latency execution of control loops, typically used in motor drives, power converters, and other applications where timing predictability is critical. The C2000 family sits in the power management and embedded control hierarchy, bridging general-purpose MCUs and dedicated DSPs for real-time signal processing.
Key features include InstaSPIN-FOC support for sensorless field-oriented control, an automotive AEC-Q100 qualification, and a 100 MHz CPU with FPU and TMU. The CLB enables custom digital logic to offload the CPU, while PGAs and SDFM provide signal conditioning and isolated sensing capabilities.
The TMS320F280040C-Q1 is packaged in an LQFP-64 (PM) form factor, offering a compact footprint for automotive control units. Its real-time performance makes it suitable for industrial motor drives, solar inverters, digital power supplies, and electric vehicle powertrains.
In a typical application, the MCU reads current and voltage through integrated ADCs, computes control efforts using the FPU/TMU, and drives power stages via PWM peripherals. Designers should decouple the supply rails with ceramic capacitors and pay attention to the exposed thermal pad for proper heat spreading.

Applications typiques
TMS320F280040C-Q1 convient pour 6 applications: Industrial Motor Drive, Solar Inverter, Digital Power Supply, Electric Vehicle Powertrain, Motor Control (General), Sensing and Signal Processing.
Industrial Motor Drive
The TMS320F280040C-Q1's 100 MHz C28x core with FPU and TMU enables fast computation of field-oriented control algorithms, essential for real-time motor torque and speed regulation. Its InstaSPIN-FOC support removes the need for manual motor parameter identification, reducing development effort. In a typical drive, the MCU reads phase currents via ADCs (amplified by PGAs), calculates PWM commands, and drives a gate driver with integrated protection. The high PWM resolution and configurable logic block (CLB) reduce CPU load by handling dead-time and fault logic in hardware, allowing deterministic execution at high controller frequencies.
Recommandé
Solar Inverter
The MCU's 100 MHz processing with FPU/TMU is ideal for implementing maximum power point tracking (MPPT) and grid synchronization algorithms in solar inverters. It manages multiple high-speed ADC channels to sample photovoltaic panel voltage/current and controls the DC-DC stage via PWM. The SDFM module enables isolated sigma-delta sensing of currents on the grid side, simplifying compliance with safety standards. With its automotive-grade reliability, the device performs robustly in outdoor environments, ensuring high efficiency and low harmonic distortion in the injected grid current.

Digital Power Supply
For digital power conversion, the TMS320F280040C-Q1 provides the necessary real-time control performance to regulate output voltage and current with high bandwidth. Its 100 MHz CPU, FPU, and TMU enable software-defined control loops that can adapt to load changes dynamically. The CLB implements hardware-based protection and interlocking logic, reducing latency and ensuring safe operation. The device integrates multiple ADCs and PWM with precision timers, allowing tight coupling of sampling and actuation. This reduces component count and enables flexible firmware updates to meet different power specification requirements.

Electric Vehicle Powertrain
The TMS320F280040C-Q1 is designed for automotive electric vehicle (EV) powertrain control, offering AEC-Q100 qualification and a wide operating temperature range. Its 100 MHz C28x core with TMU accelerates trigonometry-heavy torque and flux calculations, which are critical in permanent magnet motor control. The sigma-delta filter module (SDFM) enables isolated current sensing in high-voltage traction drives, while the configurable logic block (CLB) can implement hardware-based fault protection at nanosecond speeds. The device interfaces with gate drivers, high-voltage battery monitors, and CAN, ensuring reliable operation in the harsh automotive environment.

Motor Control (General)
In general motor control applications (BLDC, PMSM, and induction motors), the TMS320F280040C-Q1 provides an optimal balance of performance and cost. Its 100 MHz FPU and TMU allow hardware-accelerated evaluation of trigonometric functions, which is the computational bottleneck in FOC. The integrated PGAs amplify small shunt signals, removing the need for external op-amps and reducing BOM cost. With InstaSPIN-FOC, developers can quickly bring up sensorless control in days. The CLB can also offload encoder decoding and PWM generation, freeing the CPU for higher-level control tasks.

Sensing and Signal Processing
The TMS320F280040C-Q1 integrates a sigma-delta filter module (SDFM) and programmable gain amplifiers (PGAs) that enable high-accuracy sensor interfaces without additional analog front-end ICs. In applications such as current sensing for power monitoring, the SDFM can directly process sigma-delta streams from isolated modulators, providing digital filtering and offset correction. The device's 100 MHz TMU accelerates math functions for signal conditioning and calibration. Combined with its on-chip ADC, the MCU can implement closed-loop compensation for temperature drift and gain error, ensuring excellent measurement accuracy.

Notes de conception
The TMS320F280040C-Q1 consumes significant power when running at 100 MHz with the FPU and TMU active. The LQFP-64 (PM) package has a thermal resistance of approximately 35 C/W (junction-to-ambient) with a standard 1 oz copper PCB. For applications exceeding 150 mW, a copper pour under the exposed pad and a thermal via array are recommended to maintain junction temperature below 125 C. Use at least 4 thermal vias connected to the ground plane.
Place a 0.1 uF ceramic capacitor close to each VDD pin and a 1 uF capacitor on VDDA. Use a star-ground topology for analog and digital grounds, connecting them at a single point. Route ADC input traces away from switching PWM outputs to minimize crosstalk. For noisy environments, add a ferrite bead on the VDD supply. Keep the crystal or oscillator layout short and direct to avoid parasitic capacitance.
Do not exceed the recommended supply voltage, and wait for the oscillator to stabilize before executing code. Ensure that the watchdog timer is configured properly during low-power modes. When using the CLB, verify that all logic connections are correctly mapped to avoid glitches at startup. Also, check that PGA inputs are not overdriven beyond the ADC range to prevent damage.
