Deciphering Texas Instruments' New MCU Series: TMS320F28P55x & F29H85x Lead Trend of Intelligentization

2024-11-25

With the rapid development of technology, microcontrollers (MCU), as the core components of electronic devices, directly relate to the competitiveness and market performance of products. Recently, global semiconductor giant Texas Instruments (TI) has launched two new real-time microcontroller series - the TMS320F28P55x series and the F29H85x series, once again demonstrating its profound foundation and innovative strength in the field of MCU.

01 TMS320F28P55x Series: Real-Time MCU with Integrated NPU

The TMS320F28P55x series is a shining star in Texas Instruments' C2000 real-time MCU family. This series of MCUs not only inherits the C2000 series' consistent high real-time performance and excellent processing capabilities but also achieves a significant breakthrough in intelligence. The TMS320F28P55x series is built on the 32-bit C28x DSP core, with a main frequency of up to 150MHz. The C28x DSP core is specifically optimized for real-time applications, capable of efficiently executing data and instructions in parallel. Its processing capabilities are outstanding, supporting advanced features such as a floating-point unit (FPU), a trigonometric function accelerator (TMU), and VCRC, further enhancing the system's processing power and data integrity verification capabilities.

The biggest highlight of the TMS320F28P55x series is the integrated neural processing unit (NPU), which excels in high-precision, low-latency fault detection functions. The NPU is designed for deep learning calculations, with very high computational efficiency and energy efficiency, capable of completing large-scale neural network computation tasks in a short time. The NPU can handle 600–1200MOPS (million operations per second) and provides model support for arc fault detection or motor fault detection, improving the NN inference cycle by up to 10 times compared to software-only implementations. The NPU's high efficiency, low latency, stability, and programmability make the TMS320F28P55x series MCU outstanding in handling complex algorithm models, providing strong assurance for system intelligence upgrades.

02 F29H85x Series: 64-bit C29 DSP Core

Compared to the TMS320F28P55x series, the F29H85x series excels in high performance and high reliability. This series of MCUs adopts advanced manufacturing processes and packaging technologies, achieving industry-leading levels in performance, power consumption, and reliability. The F29H85x series is built on Texas Instruments' new 64-bit C29 digital signal processing core, with real-time performance more than double that of its predecessor, the C28, featuring three C29 cores. The new F29H85x processor series with the C29 DSP core has TI's very long instruction word VLIW architecture, supporting up to 8 instructions per cycle. It provides network security features, including a fully isolated hardware security module for system protection. Additionally, the F29H85x series has passed the highest level of automotive safety integrity level ASIL D and safety integrity level SIL 3 certification.

At the same time, the F29H85x series MCU also excels in reliability. This series of MCUs adopts various protective measures, such as over-temperature protection, short-circuit protection, over-voltage protection, etc., ensuring that the system can still operate stably under harsh conditions. In addition, this series of MCUs also supports ECC protection functions, effectively preventing data corruption and loss, providing strong assurance for system data security.

Application Areas

The main application areas for TI's two new products include motor drivers, electrical appliances, hybrid, electric and powertrain systems, solar and electric vehicle charging, digital power, body electronics and lighting, testing and measurement, etc. Especially in some countries and regions, photovoltaic storage and charging systems and digital power need to be mandatorily equipped with arc fault detection capabilities to enhance system safety and reliability.

Conclusion

The TMS320F28P55x series and F29H85x series of MCUs launched by Texas Instruments not only inherit the C2000 series' consistent high real-time performance and excellent processing capabilities but also achieve significant breakthroughs in intelligence, high performance, and reliability. These two new products will inject new vitality into the development of industrial automation, smart homes, electric vehicles, and other fields, promoting the industry to develop in a more intelligent, efficient, and reliable direction. In the future, with the continuous progress of technology and the expansion of application scenarios, these two MCUs are expected to demonstrate their unique advantages and value in more fields.
