TMS320F280021-Q1 Présentation

TMS320F280021-Q1 is an automotive-grade C2000 real-time microcontroller from Texas Instruments, featuring a 32-bit CPU running at 100 MHz with floating-point unit (FPU) and trigonometric math unit (TMU). It integrates 32 KB of flash memory and is available in an LQFP-48 package.

The C2000 family of microcontrollers is specifically designed for real-time control applications in power electronics, offering ultra-low latency and high performance. The TMS320F280021-Q1 belongs to the TMS320F28002x series, which supports high power density, high switching frequencies, and is optimized for use with GaN and SiC technologies.

Key features include 100 MHz CPU speed, FPU for efficient floating-point computation, and TMU for fast trigonometric calculations, essential for complex control algorithms. The automotive qualification (-Q1) ensures operation in harsh environments and compliance with AEC-Q100 requirements, making it suitable for automotive applications such as motor control, DC-DC converters, and onboard chargers.

The device is designed to deliver deterministic, low-latency performance for closed-loop control systems. The C2000 architecture includes specialized hardware for real-time control, enabling precise PWM generation, high-resolution ADC sampling, and fast interrupt handling. The TMU accelerates trigonometric operations used in space vector modulation (SVM) and other motor control algorithms, reducing CPU load.

Typical applications include industrial motor drives, automotive HEV/EV power electronics, solar inverters, server power supplies, and other power conversion systems. The TMS320F280021-Q1's combination of real-time performance, automotive-grade quality, and support for wide-bandgap semiconductors (SiC and GaN) makes it a robust choice for modern power electronics.

When designing with this MCU, ensure proper power supply decoupling and consider thermal management for high-frequency switching applications. The C28x core requires careful handling of the boot mode pins to configure the startup sequence. Additionally, the TMU and FPU enable efficient implementation of advanced control algorithms, but memory constraints (32 KB flash) should be planned accordingly.

Notes de conception

Place 0.1uF and 1uF ceramic capacitors close to each VDD and VDDA pin. Use a 10uF bulk capacitor on the 3.3V supply. Ensure the analog supply (VDDA) is properly filtered with a ferrite bead to reduce noise from digital switching. Follow the datasheet's recommended decoupling scheme to maintain stable operation at 100 MHz.

The boot mode pins (GPIO72, GPIO73, GPIO74, or similar) must be configured correctly at reset to select the desired boot source (e.g., SCI, SPLASH). Incorrect boot configuration can prevent the MCU from starting. Consult the datasheet's Boot ROM chapter. Also, avoid drawing large currents from GPIO pins directly; use external drivers for high-load peripherals.

At 100 MHz operation, the TMS320F280021-Q1 dissipates power based on supply voltage and activity. Ensure adequate copper pour and thermal vias under the LQFP-48 package to keep the junction temperature within the recommended range. For automotive applications, consider ambient temperatures up to 125°C; calculate power dissipation using the datasheet's power consumption tables.

Use a four-layer PCB with a solid ground plane. Route analog and digital grounds separately and join at a single point to minimize noise. Keep the crystal oscillator circuit short and away from high-current traces. For high-frequency switching, maintain short trace lengths for PWM outputs to reduce EMI and ensure signal integrity.
