company blog about New MCU F28P550SJ9PMR: Texas Instruments C2000™ Real-Time Microcontroller

Today's engineers are challenged to design systems that make accurate, intelligent decisions in real time to perform functions such as arc fault detection in solar and energy storage systems, and motor bearing fault detection for predictive maintenance. As the industry's first real-time MCU with an integrated neural processing unit, Texas Instruments' new C2000 TMS320F28P55x family addresses these challenges by guaranteeing consistent performance for real-time processing.

Running convolutional neural network (CNN) models with an integrated neural network processing unit (NPU), the TMS320F28P55x family of MCUs reduces the burden on the main CPU, resulting in latency that is 5 to 10 times lower than software implementations, enabling faster and more accurate decisions. Additionally, models running on the integrated NPU can be trained to learn and adapt to different environments, helping the system achieve better than 99 percent fault detection accuracy for more informed decisions at the edge. Texas Instruments' complete AI toolchain includes models optimised and tested for specific applications, making the AI model development process easy for engineers of all experience levels.

The Mingjiada [Supply, Acquisition] F28P550SJ9PMR is a high-performance, 32-bit fixed-point microcontroller (MCU) in the Texas Instruments C2000™ family, designed for power electronics applications to achieve high efficiency.
