Abstract
Texas Instruments (TI) is one of the world's largest semiconductor companies, with a broad portfolio specifically targeting industrial applications. From C2000 microcontrollers for digital power and motor control, to isolated CAN transceivers for industrial fieldbus communications, to high-precision analog components for sensor interfaces — TI's industrial lineup is designed for robustness, long availability, and wide temperature range operation.

2. Industrial Application Areas
2.1 Factory Automation and PLCs
PLCs require real-time processing, reliable communications, and robust analog front-ends. TI's C2000 MCUs handle real-time control loops, while CAN transceivers interconnect PLCs and distributed I/O modules.
2.2 Motor Drives and Motion Control
Three-phase motor drives demand high-speed PWM generation, precise current measurement, and robust communication. The TMS320F28335's ePWM module generates complementary PWM signals with programmable dead-band for three-phase inverter legs.
2.3 Industrial Power Supply and Conversion
Digital power supplies use TI C2000 MCUs to implement control algorithms that maximize efficiency across load ranges. The FPU handles digital filters and PLL synchronization.
3. Selection Guide
| Application | Primary Recommendation |
|---|---|
| Digital power / solar inverter | TMS320F28335 |
| Motor control (general purpose) | TMS320F28335 |
| Industrial CAN (5V bus, needs isolation) | ISO1050 |
| Industrial CAN (3.3V node) | SN65HVD230 |
| PLC analog inputs | TMS320F28335 + ISO1050 combo |
4. How to Source and Evaluate TI Industrial Parts
TI's industrial-grade parts typically offer extended temperature ranges and 10+ year availability — critical for industrial equipment with decades-long field life.
Engineers should: download official data sheets from ti.com; use WEBENCH for power supply design; order samples for board-level evaluation; check availability via authorized distributors.
5. FAQ
Q: What is the difference between TMS320F28335 and newer C2000 parts like F28004x? A: The F28335 (Delfino) uses C28x at 150 MHz with external FPU. The newer F28004x (Piccolo) integrates FPU on-chip at up to 100 MHz, includes a CLA for offloading control loops, and offers smaller packages.
Q: Can ISO1050 and SN65HVD230 be mixed on the same CAN bus? A: Yes, both are CAN 2.0B compliant and ISO 11898-2 compatible. Position ISO1050 on nodes requiring ground-loop isolation.
Q: Does TI offer evaluation modules? A: Yes. TI provides LaunchPad and controlCARD evaluation platforms for C2000 MCUs.
6. Conclusion
Texas Instruments remains a cornerstone vendor for industrial semiconductors. The TMS320F28335 provides a proven real-time control platform with extensive ecosystem support. The ISO1050 and SN65HVD230 cover the two most common industrial CAN bus voltage domains with robust ESD protection.
