What are the key features of TMS320F280049CRSH?
- 100 MHz C28x DSP core with Trigonometric Math Unit (TMU) for fast sin/cos calculations in motor control algorithms
- High-Resolution PWM (HRPWM) with 150 ps resolution for precision power converter switching
- Control Law Accelerator (CLA) co-processor offloading control loops from the main CPU for 2× effective throughput
- Configurable Logic Block (CLB) enabling custom digital logic without external FPGAs or CPLDs
- 12-bit ADC with simultaneous sampling at up to 3.5 MSPS for high-bandwidth feedback in real-time control
What is TMS320F280049CRSH used for?
The TMS320F280049CRSH excels in three-phase motor drives, servo controllers, and solar inverters where its 100 MHz C28x core and HRPWM deliver cycle-accurate real-time control with minimal latency. Industrial power supplies and digital power modules leverage its CLA co-processor and 12-bit ADC for closed-loop voltage and current regulation at switching frequencies above 100 kHz. It is also deployed in EV on-board chargers and uninterruptible power supplies requiring the TMU's hardware trigonometric acceleration to sustain fast field-oriented control at full load.

Frequently Asked Questions
How does the TMS320F280049CRSH's Control Law Accelerator improve motor control loop execution time?
The CLA is an independent 32-bit floating-point co-processor running at 100 MHz in parallel with the C28x main core. By offloading inner control loops such as current regulation to the CLA, designers achieve effective dual-core throughput, allowing PI loops to execute in under 1 µs without stalling main CPU tasks like communications or fault handling.
What PWM resolution does the TMS320F280049CRSH provide, and why does it matter in power supply design?
The TMS320F280049CRSH features High-Resolution PWM with 150 ps edge resolution, far finer than the 10 ns typical of standard 100 MHz timers. In DC-DC converters operating above 200 kHz, this resolution allows precise duty-cycle steps below 0.01%, reducing output ripple and enabling tighter voltage regulation without analog trim circuits.
Can the TMS320F280049CRSH replace a TMS320F28004x device in an existing PCB, and what should engineers verify?
The TMS320F280049CRSH is a member of the TMS320F28004x family and is pin-compatible with other QFN variants in that series, so board re-spin is typically not required. Engineers should verify Flash size requirements (256 KB on this device), confirm CLB and CLA usage matches their firmware, and validate that the operating temperature range of -40°C to +125°C meets the application profile.
Which communication peripherals are integrated on the TMS320F280049CRSH for industrial network connectivity?
The device integrates multiple SCI (UART-compatible), SPI, I2C, and CAN 2.0B ports, plus an FSI (Fast Serial Interface) for deterministic multi-device synchronization at up to 200 Mbps. This mix of 5 V-tolerant GPIO and digital isolation-friendly interfaces makes it straightforward to connect to RS-485 field buses, CAN networks, and isolated gate drivers in an 8-channel configuration.
