TMS320F280023-Q1 Overview
A C2000 real-time microcontroller is a specialized MCU architecture optimized for closed-loop control applications, such as motor control and digital power conversion. It combines the versatility of a microcontroller with the deterministic execution required for real-time algorithms. The C2000 family sits within the broader power management and embedded control hierarchy, offering precise PWM generation, fast ADC conversion, and hardware math acceleration.
Key features include a 100 MHz C28x CPU, FPU for single-precision floating-point calculations, TMU for accelerating trigonometric functions, and 64-KB flash. The automotive qualification (-Q1) ensures compliance with AEC-Q100 standards for use in harsh vehicle environments. The device supports multiple PWM channels and communication interfaces, enabling complex control loops with minimal latency.
The architectural design of the F28002x family focuses on real-time performance, with a Harvard bus architecture and dedicated hardware accelerators. The FPU and TMU offload intensive math from the CPU, allowing higher control frequencies and more complex algorithms. The flash memory is tightly coupled to the CPU to minimize wait states, ensuring deterministic execution.
Typical applications include automotive motor control, digital power supplies, solar inverters, EV charging systems, industrial drives, and battery management. These applications benefit from the MCU's high-speed PWM, low-latency ADC, and robust thermal performance. The device is also compatible with GaN and SiC power devices, supporting next-generation high-efficiency designs.
When designing with this MCU, ensure proper power supply decoupling and consider the thermal budget at 100 MHz. The automotive qualification makes it an ideal choice for safety-critical systems, though designers should still perform worst-case analysis for temperature and voltage transients.

Design Notes
The TMS320F280023-Q1 requires a stable power supply with proper decoupling. Use separate decoupling capacitors (100nF and 10uF) on the VDD and VDDIO pins. Ensure the core voltage is within the specified range; the internal regulator may be used. Place the ceramic capacitors close to the IC to minimize inductance. For automotive designs, consider the operating temperature range and ensure the voltage supply is robust to load transients (e.g., from motor switching).
The MCU's power dissipation is low, but in automotive environments, ensure adequate thermal dissipation. Use a copper pour under the package (if QFN) or thermal vias. The C2000 device should not exceed the maximum junction temperature; check the datasheet for thermal resistance. At 100 MHz with active peripherals, the current draw is moderate, but a heat sink may not be needed unless integrated with high-power components. Keep the layout compact to avoid thermal coupling with power stages.
For real-time control, keep the crystal/oscillator close to the device and route the oscillator traces with a clean ground return. Use a proper ground plane. Ensure the ADC reference pins have a low-impedance path. For PWM outputs driving gate drivers, use series resistors to reduce ringing. Avoid running noise-sensitive signals (like ADC inputs) near high-speed digital lines. For functional safety, consider using the device's lockstep or watchdog features.
