TI's new single-core microcontrollers bring high-precision, high-performance 16-bit ADCs for industrial control applications

High frequency probe and high frequency line can be customized to meet specific requirements.

The industry-leading dual-core C2000 Delfino MCUs are pin and software compatible, offering scalable solutions for variable speed drives, frequency converters, power conversion systems, and renewable energy applications. These MCUs are designed to meet the evolving demands of industrial control and power management systems.

Beijing, August 27, 2014 — Texas Instruments (TI) announced the launch of the new C2000® Delfino® 32-bit F2837xS microcontroller (MCU), a powerful single-core solution tailored for industrial real-time control applications. This MCU introduces a range of advanced features that make it ideal for a variety of high-performance control systems.

As the first single-core MCU in the industry to include four 16-bit analog-to-digital converters (ADCs), the F2837xS provides precise feedback for power control applications. It is also compatible with the recently released dual-core C2000 Delfino F2837xD MCU, enabling a smooth transition from high-performance designs to medium-control systems. For users of previous Delfino F2833x MCU families, the F2837xS offers an upgraded single-core option with enhanced performance and improved peripheral support.

Key features and benefits of the F2837xS MCU include:

• Combining the C28x CPU with the Real-Time Control Accelerator (CLA) delivers 400 MIPS of floating-point performance, allowing efficient handling of multiple control tasks.
• Integrated hardware accelerators like the Triangular Mathematical Unit (TMU) and Viterbi Complex Unit (VCU II) significantly improve performance in complex mathematical operations and communication algorithms.
• Intelligent system partitioning offloads demanding control loops to the CLA, freeing up the main CPU for other critical tasks such as diagnostics or application management.
• Four 16-bit ADCs provide accurate feedback in power control systems, supporting applications like motor monitoring and resolver signal decoding.
• Advanced peripherals such as sigma-delta demodulators, comparators, DACs, and communication interfaces enhance system integration and reduce BOM costs.
• Eight debugged delta-sigma channels simplify threshold comparisons and integrate seamlessly with TI’s AMC1204 isolated modulator.
• Easy migration from older F2833x MCUs due to shared architecture, peripherals, and software compatibility, ensuring a smooth upgrade path.
• Scalable design allows for future expansion and pin/soft-compatible architectures, reducing development time and costs for dual-core devices.
• Access to controlSUITE® software, including examples, libraries, and header files, supports centralized and efficient development.

Developers can take advantage of the same development platform used for the Delfino F2837xD Experimenter Kit, making it easier to evaluate and implement the F2837xS MCU in their projects. The modular controlCARD format further enhances flexibility, allowing designers to use the controlCARD with existing C2000 application suites.

The F2837xS MCU family includes several variants such as the TMS320F28377S, TMS320F28375S, and TMS320F28374S, each with different memory and peripheral configurations to suit a wide range of applications. Developers can also evaluate the new MCU using the Delfino F2837xD Experimenter Kit Expansion Base or purchase the controlCARD separately.

Samples of the full-featured F28377S MCU are now available, giving developers early access to this next-generation solution for industrial control and power management systems.
