TMS320F28374SPTPS 概述
A microcontroller (MCU) is a compact integrated circuit designed to govern a specific operation in an embedded system. It contains a processor core, memory, and programmable input/output peripherals. The C2000 family is a series of MCUs optimized for real-time control, combining the processing power of a digital signal processor with the peripherals of a microcontroller. This makes them ideal for applications requiring precise, high-speed calculations and control loops.
Key features include a 12-bit ADC, multiple communication interfaces (SCI, SPI, I2C, CAN), and enhanced PWM modules. The device supports functional safety (FuSa) applications, making it suitable for automotive and industrial systems. The 176-pin HLQFP package provides ample I/O for complex control systems.
The TMS320F28374S architecture includes a dual-core option (TMS320F28374D) and a single-core variant, with the 'S' denoting single-core. The CLA is a parallel processing unit that can execute control algorithms independently, offloading the main CPU. The FPU and TMU accelerate mathematical operations, crucial for real-time control algorithms.
Typical applications include industrial motor drives, solar inverters, electric vehicle powertrains, and digital power supplies. The device's high-speed ADC and PWM modules enable precise current and voltage sensing and control.
When designing with this MCU, ensure proper decoupling of the 1.2V core supply and use the internal voltage regulator. The exposed pad must be soldered to the PCB ground plane for thermal management.

设计说明
The TMS320F28374SPTPS requires a 1.2V core supply and 3.3V I/O supply. Use low-dropout regulators (LDOs) like TPS7A4700RGWR for clean power. Place 100nF decoupling capacitors close to each power pin and a 10uF bulk capacitor near the VDD pin. Ensure the core supply is stable within ±5% to avoid malfunction.
The 176-pin HLQFP package has an exposed pad that must be soldered to the PCB ground plane for effective heat dissipation. For high-power applications, use thermal vias under the pad to conduct heat to inner layers. The maximum junction temperature is typically 125°C; calculate power dissipation based on I/O loading and clock frequency to ensure adequate cooling.
For optimal signal integrity, route high-speed signals (e.g., PWM, ADC inputs) with controlled impedance and minimize trace lengths. Keep analog and digital grounds separate and connect them at a single point. Place the ADC reference decoupling capacitors close to the ADC pins to reduce noise.
