TMS320F280034-Q1 概要
A real-time microcontroller (MCU) is a specialized processing unit optimized for deterministic, low-latency control of electrical and electromechanical systems. The C2000 family extends the traditional MCU concept by integrating a digital signal processor (DSP) architecture with control peripherals such as high-resolution PWM, ADCs, and communication interfaces. This allows the MCU to execute complex control algorithms in a single clock cycle, enabling faster loop rates and higher power density in converters and inverters. C2000 devices are widely used in motor drives, EV powertrain, renewable energy systems, and digital power supplies where predictable timing is critical.
Key features of the TMS320F280034-Q1 include a 120-MHz C28x CPU with floating-point unit (FPU), trigonometric math unit (TMU), control law accelerator (CLA), 128-KB flash, hardware AES acceleration, and CAN-FD. The device includes a CRC engine and multiple timers, and supports a 3.3-V supply. The automotive qualification ensures operation over the extended temperature range and compliance with AEC-Q100 requirements.
The architecture of the C2000 MCU is centered on the C28x DSP core, which combines the math capabilities of a DSP with the peripheral set of an MCU. The FPU accelerates floating-point control algorithms, while the TMU accelerates trigonometric operations used in motor control. The CLA is an independent coprocessor that can execute real-time control tasks in parallel, offloading the main CPU. The AES module provides hardware-accelerated security, and CAN-FD supports higher bandwidth automotive networking.
Typical applications include electric vehicle traction inverters, industrial motor drives, digital power supplies, and solar inverters. The high switching frequency support and low-latency control loop make this MCU suitable for GaN and SiC power stages, where fast response is essential for efficiency and reliability.
Designers should note that precise supply decoupling and a clean ground plane are critical for reliable ADC operation and deterministic performance. Refer to the TI TMS320F28003x datasheet and application notes for recommended PCB layout, PLL configuration, and flash wait-state setup.

設計ノート
For reliable operation of the TMS320F280034-Q1, decouple each VDD and VDDIO pin with 100nF ceramic capacitors placed as close to the pins as possible, and a bulk 4.7uF capacitor near the power entry. The MCU has separate analog and digital power supplies, so use ferrite beads between them to reduce noise coupling. Provide a clean 3.3V rail and maintain power-up sequencing per the datasheet.
Route the ADC input traces with ground guarding and keep them away from switching nodes to minimize noise. The oscillator and PLL pins need a dedicated ground area and short traces. For the LQFP-48 package, use a solid ground pour on the bottom layer to enhance thermal dissipation and reduce inductance. Follow the TI recommended layout guidelines in the TMS320F28003x datasheet.
Do not leave boot configuration pins floating, as this may cause unexpected boot behavior. Configure the TRST pin appropriately to avoid unintentional test mode. Ensure flash wait states are set for 120MHz operation; otherwise, incorrect flash reads can occur. Refer to the TMS320F28003x datasheet for the recommended flash wait-state and PLL configuration values.
