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

High frequency probe, high frequency line can be customized with other specifications

The industry-leading dual-core C2000 Delfino MCUs are pin and software compatible, offering scalable solutions for variable speed drives, frequency converters, power systems, and renewable energy applications. These MCUs provide a robust foundation for industrial control designs, ensuring flexibility and performance in real-time environments.

On August 27, 2014, Texas Instruments (TI) announced the launch of the new C2000 Delfino 32-bit F2837xS microcontroller (MCU), introducing a powerful single-core series tailored for industrial real-time control applications. This MCU is the first in its class to feature four 16-bit analog-to-digital converters (ADCs), delivering precise feedback in power control scenarios. It is designed to work seamlessly with the recently introduced dual-core F2837xD MCU, enabling developers to transition smoothly from high-performance applications to medium-level control systems.

For users of the previous Delfino F2833x family, the F2837xS offers an upgraded single-core solution. Developers can leverage their existing investments in F2833x MCUs by migrating to the F2837xS, which provides enhanced CPU performance, advanced analog features, and improved control peripherals.

Key features and benefits of the F2837xS MCU include:

• Combines the C28x core with the Real-Time Control Accelerator (CLA) to deliver 400 MIPS of floating-point performance, allowing efficient handling of multiple control tasks.
• Integrated hardware accelerators such as the Triangular Mathematical Unit (TMU) and Viterbi Complex Unit (VCU II) enhance trigonometric and complex mathematical operations, improving performance in signal processing and communication applications.
• Intelligent system partitioning allows offloading demanding control loops to the CLA, freeing up the main CPU for other critical tasks like diagnostics or application management.
• Four 16-bit ADCs provide accurate feedback in power control applications, making it ideal for monitoring motor voltage and current, as well as decoding resolver signals.
• Advanced peripherals including sigma-delta demodulators, comparators, DACs, and communication interfaces help maximize system integration and reduce BOM costs.
• Eight debugged delta-sigma channels support threshold comparison and integrate seamlessly with the TI AMC1204 isolated modulator.
• Easy migration from F2833x MCUs due to shared architecture, peripherals, and software compatibility, enabling faster development and better performance.
• Scalable design supports future dual-core devices, helping accelerate time-to-market and reduce development costs through pin- and software-compatible architectures.
• ControlSUITE software provides examples, header files, and libraries for centralized development, available for free download at ti.com.

New tools make development easier. The F2837xS shares the same development platform as the F2837xD, using the Delfino F2837xD Experimenter Kit based on the C2000 controlCARD form factor. This allows designers to use the controlCARD with existing C2000 application suites for seamless integration.

The F28377S MCU (TMX320F28377S) is now available for sampling. With variants like TMS320F28376S, TMS320F28375S, and TMS320F28374S offering different memory and peripheral configurations, TI gives designers more options. Additionally, the modular controlCARD (TMDXCNCD28377D) and the Delfino F2837xD Experimenter Kit Expansion Base (TMDXDOCK28377D) allow for flexible evaluation and separate purchase of the controlCARD.
