For engineers reviewing the TMS320F280025PTSRG4 datasheet, TMS320F280025PTSRG4 pinout, TMS320F280025PTSRG4 application, or TMS320F280025PTSRG4 equivalent, key selection criteria include high-resolution PWM timing, on-chip analog signal chain integration, functional safety documentation support (ISO 26262/IEC 61508), and 48-pin LQFP package compatibility with industrial temperature range (–40°C to 125°C).
Technical Context
The TMS320F280025PTSRG4 implements a deterministic C28x DSP core augmented by TMU for trigonometric acceleration and VCRC instructions for fast CRC computation-enabling real-time NLPID control loops. Its dual ADC subsystem feeds four post-processing blocks per converter, tightly synchronized with ePWM triggers for closed-loop current/voltage regulation.
Control peripherals include eight high-resolution ePWM channels with hardware trip zones and dead-band generation, three eCAP modules (one with HRCAP), two eQEP interfaces for motor position feedback, and four windowed comparators with integrated 12-bit DAC references-supporting fast overcurrent protection and adaptive gate drive timing in SiC/GaN-based power stages.

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F280025PMR | 64-pin LQFP package; adds 13 more GPIO and 2 additional ADC channels vs. PT package. | Better suited for designs requiring expanded analog monitoring or complex I/O routing. | Select when board layout allows larger footprint and additional analog inputs are needed for multi-sensor feedback. |
| TMS320F280023PTSR | 64KB flash (vs. 128KB), no CLB, same 48-pin LQFP package and peripheral set. | Targeted at cost-sensitive applications with simpler control requirements and smaller firmware footprints. | Choose for entry-level solar microinverters or low-power motor drives where CLB and full flash capacity are unnecessary. |
Compared with TMS320F280025PMR, the TMS320F280025PTSRG4 offers identical real-time performance in a smaller 48-pin footprint but trades GPIO count and ADC channel count for board space savings; versus TMS320F280023PTSR, it delivers double flash, CLB logic, and enhanced safety documentation-justifying premium use in certified industrial power systems.

FAQ
What is the maximum operating frequency of the TMS320F280025PTSRG4 CPU core?
The TMS320F280025PTSRG4 features a C28x 32-bit DSP core running at 100MHz, delivering deterministic real-time performance for floating-point and fixed-point control algorithms. This clock speed is fully supported across the specified industrial temperature range (–40°C to 125°C) and enables sub-microsecond execution of critical motor control or digital power loops. The TMS320F280025PTSRG4 maintains this frequency without throttling under full load and thermal conditions.
Does the TMS320F280025PTSRG4 support functional safety certification documentation?
Yes, the TMS320F280025PTSRG4 is supported by Texas Instruments' functional safety documentation package for ISO 26262 (ASIL-B), IEC 61508 (SIL-3), and IEC 60730 compliance. This includes FMEDA reports, safety manuals, and diagnostic coverage analysis-specifically validated for the TMS320F280025PTSRG4 device variant. The TMS320F280025PTSRG4 also integrates hardware features such as ECC memory, windowed watchdog timers, and memory built-in self-test (MBIST) to meet safety mechanism requirements.
How many high-resolution PWM channels does the TMS320F280025PTSRG4 provide?
The TMS320F280025PTSRG4 provides eight high-resolution ePWM channels (ePWM1–ePWM4, each with A/B outputs) capable of 150ps resolution, enabling precise timing control for SiC and GaN power devices. These channels include integrated dead-band generation, hardware trip zones, and event synchronization with ADC conversions. The remaining six ePWM channels operate at standard resolution. All 14 ePWM channels are accessible in the 48-pin PT package of the TMS320F280025PTSRG4.
What analog-to-digital converter (ADC) capabilities does the TMS320F280025PTSRG4 include?
The TMS320F280025PTSRG4 integrates two independent 12-bit, 3.45MSPS ADCs (ADC-A and ADC-C) with up to 14 external input channels in the 48-pin package. Each ADC includes four post-processing blocks (PPBs) for hardware-based averaging, offset correction, and window comparison. The TMS320F280025PTSRG4 supports simultaneous sampling, hardware-triggered conversions synchronized to ePWM events, and direct result loading into DMA buffers-reducing CPU overhead in high-speed control loops.
Is the TMS320F280025PTSRG4 pin-compatible with other devices in the F28002x family?
The TMS320F280025PTSRG4 shares identical pinout, electrical characteristics, and package dimensions with other 48-pin LQFP variants in the F28002x family-including TMS320F280023PTSR and TMS320F280021PTSR. This allows drop-in replacement within the same PT package footprint. However, feature differences exist: the TMS320F280025PTSRG4 includes 128KB flash and CLB logic not present in lower-tier variants, so firmware and peripheral initialization must be verified for compatibility.
