TI TMS320F28P55x MCU Deep Dive: Performance, Pricing & Industrial Applications

TMS320F28P55x Series Performance and Applications In-Depth Analysis

From late 2024 to early 2025, Texas Instruments (TI) officially released the TMS320F28P55x series of real-time microcontroller chips. Since its launch, sales of this series have steadily increased, with shipments exceeding one million. They have performed particularly well in areas such as new energy motor control, photovoltaic inverters, industrial automation, and energy storage PCS, making them the preferred solution for industry engineers. As an electronic component trader, Kingrole selects the most cost-effective microcontroller chips from a variety of models based on the client's project scale, performance requirements, and cost targets. We also ensure stable supply channels, helping clients shorten R&D cycles and reduce procurement costs.

Microcontroller Chips: A Complete Analysis of Products and Models

The TMS320F28P55x series is TI's latest generation of C2000 real-time control MCUs for 2025, covering multiple models: F28P550D, F28P550Q, F28P552R, and F28P554C. The F28P550Q, with its 200MHz C28x CPU, dual-core architecture, 512KB Flash, two CLA coprocessors, and rich high-resolution PWM resources, is currently the most popular model. It is widely used in electric drives, servos, and high-performance digital power supplies.

Technically, this MCU series integrates a 16-bit high-speed ADC, configurable logic modules, and a DSP core with floating-point support. Compared to the previous-generation F2837x series, it offers approximately 25% higher overall computing performance and 10% lower power consumption. These upgrades enable it to perform even better in demanding real-time, multi-tasking scenarios.

Microcontroller Chip: Performance and Architectural Advantages

The TMS320F28P55x's greatest strength lies in its dual-core architecture combined with high-speed peripherals. The primary C28x core handles primary control tasks, while the secondary CLA core independently runs control loops, reducing the primary core's load and improving system responsiveness. Its 1.02ns resolution HRPWM ensures smoother motor control, lower noise, and higher efficiency. Compared to the STMicroelectronics STM32G4, the F28P55x leads in both PWM accuracy and ADC sampling speed, making it particularly suitable for servo control systems requiring high dynamic performance.

F28P55x Series Microcontroller Chips: Applications and Real-World Examples

New Energy Vehicle Electric Drive Control: A well-known automaker uses the F28P550Q for dual-motor system control on an 800V platform, optimizing energy recovery strategies and increasing driving range by approximately 5%.

Photovoltaic Inverter: The F28P554C is used for multi-channel MPPT control, improving photovoltaic system power generation efficiency by 3%-4%.

Energy storage BMS control board: Using the F28P552R for battery pack balancing control reduces temperature rise by 8%, extending battery life.

Industrial servo drive: The F28P550Q, combined with TI's MotorWare library, enables high-speed position loop control and improves machining accuracy.

These use cases demonstrate that the F28P55x not only meets real-time control requirements but also helps customers reduce overall bill of materials (BOM) costs and accelerate time to market.

Microcontroller Chips: Market Price and Supply Trends

In the first quarter of 2025, the spot price of the F28P550Q remained in the US$7.5-8.2 range. The F28P552R was slightly higher, approximately 5%, while the high-capacity F28P554C was even more expensive. However, demand in the high-end inverter market is strong. The global semiconductor supply chain is gradually recovering, with delivery times stabilizing at 8-10 weeks. Through Kingrole, customers can obtain authorized suppliers, avoid the risk of counterfeit goods, and obtain more favorable prices when purchasing in bulk.

Microcontroller Chips: Competitive Product Comparison

Compared to the STMicroelectronics STM32G4 and Infineon's XMC7000, the TMS320F28P55x surpasses its competitors in real-time control capabilities, PWM accuracy, and ADC bandwidth, making it particularly suitable for high-power motor drives, digital power supplies, and inverter control scenarios. Although the price per chip is slightly higher, its improved performance reduces peripheral circuitry, making it more advantageous from a system cost perspective.

Microcontroller Chips: Traders' Purchasing Recommendations

Reasonable Model Selection: For high-real-time applications, the F28P550Q is recommended. If more peripherals and storage are required, choose the F28P554C.
