Product details
Overview
TMS320F280041PMSR from Texas Instruments is a 100MHz C28x 32-bit floating-point real-time microcontroller with IEEE 754 FPU, CLA accelerator, 128KB flash, 100KB RAM, and integrated analog (3× 12-bit 3.45MSPS ADCs, 7 PGAs, 7 CMPSS). It targets high-precision motor control in EV charging power modules and solar string inverters.
For engineers reviewing the TMS320F280041PMSR datasheet, TMS320F280041PMSR pinout, TMS320F280041PMSR application, or TMS320F280041PMSR equivalent, key selection criteria include ePWM resolution (150ps), functional safety support (ASIL B certified variant available), CLA offloading capability, and 64-pin LQFP package compatibility with industrial temperature range (–40°C to 125°C).
Technical Context
The TMS320F280041PMSR implements a dual-core real-time control architecture: the main C28x CPU runs at 100MHz with FPU, TMU, and VCU-I for fast trigonometric and complex math; the independent CLA executes floating-point control loops in parallel at 100MHz. Both cores share access to ECC-protected memory and peripherals including ePWM, eCAP, and SDFM.
Its analog subsystem integrates three synchronized 12-bit ADCs (3.45MSPS), seven programmable-gain amplifiers (gain settings: 3/6/12/24), and seven windowed comparators with 12-bit DAC references-enabling simultaneous current/voltage sensing and fast overcurrent trip response in isolated 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 |
|---|---|---|---|
| TMS320F280041C | Includes Configurable Logic Block (CLB) and InstaSPIN-FOC™ ROM - adds 4-tile logic fabric and pre-validated motor control library. | Required for position manager implementations or sensorless FOC deployment without external tuning tools. | Select TMS320F280041C when CLB-based encoder interface or InstaSPIN-FOC acceleration is needed; TMS320F280041PMSR suffices for standard vector control with custom firmware. |
| TMS320F280045 | 256KB flash (vs 128KB), same 100MHz CPU/CLA, identical 64-pin PM package and peripheral set. | Preferred for complex multi-axis motion control or systems requiring large data logging buffers and dual-application firmware images. | Choose TMS320F280045 if firmware size exceeds 128KB or if future feature expansion requires additional flash headroom; otherwise TMS320F280041PMSR offers optimal cost/performance balance. |
Compared with TMS320F280041C, TMS320F280041PMSR omits CLB and InstaSPIN-FOC™ ROM but retains full CPU/CLA/ADC/ePWM capability - making it ideal for cost-sensitive, firmware-defined control systems. Against TMS320F280045, it trades flash capacity for lower unit cost while maintaining identical real-time performance and peripheral functionality.
