Product details
Overview
F280041CPMS from Texas Instruments is a 32-bit real-time microcontroller (MCU) with 100MHz C28x CPU, IEEE 754 single-precision FPU, Trigonometric Math Unit (TMU), and Control Law Accelerator (CLA) running at 100MHz. It integrates 128KB flash, 100KB ECC/parity-protected RAM, three 3.45MSPS 12-bit ADCs, 16 ePWM channels with 150ps resolution, and dual CAN interfaces. It targets high-precision motor control in EV charging power modules and solar string inverters.
For engineers reviewing the F280041CPMS datasheet, F280041CPMS pinout, F280041CPMS application, or F280041CPMS equivalent, key selection considerations include CLA offload capability for torque-loop computation, integrated PGAs (gain 3/6/12/24) for analog front-end scaling, functional safety quality-managed status per ISO 26262, and 64-pin LQFP (PM) package compatibility with industrial thermal requirements (–40°C to 125°C).
Technical Context
The F280041CPMS implements a dual-core real-time control architecture: the main C28x CPU executes deterministic control loops while the independent CLA handles background math-intensive tasks like Park transforms (13-cycle latency) and FOC inner-loop calculations-both using IEEE 754 single-precision instructions. Its analog subsystem includes seven programmable gain amplifiers (PGAs) and seven windowed comparators with 12-bit DAC references, enabling direct sensor signal conditioning and fast overvoltage trip response.
Peripherals are optimized for closed-loop power conversion: 16 ePWM channels support high-resolution dead-band generation and hardware trip zones; two CAN 2.0B ports provide robust fieldbus communication; and the Fast Serial Interface (FSI) enables isolated high-speed data transfer to auxiliary controllers or gate drivers. The device uses dual-bank flash for concurrent execute-and-program operations and supports secure boot via dual-zone code security.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F280049CPMS | 256KB flash, 4 CLB tiles, InstaSPIN-FOC™ enabled, same 64-pin PM package | Supports larger control algorithms and advanced position manager functions; required for full InstaSPIN deployment | Select when >128KB flash or CLB-based encoder emulation is needed; otherwise F280041CPMS offers cost-optimized feature set. |
| TMS320F280035CPMS | 128KB flash, CAN-FD support, enhanced security (AES-128), no CLB or InstaSPIN-FOC™ | Better suited for secure, CAN-FD–based industrial networks; lacks analog acceleration features for motor control | Prefer for new designs requiring CAN-FD or cryptographic security; avoid if PGA/CMPSS/CLA-based analog control is essential. |
Compared with TMS320F280049CPMS, F280041CPMS trades flash capacity and CLB count for lower BOM cost while retaining identical CPU/CLA performance, ADC speed, and PWM resolution-making it optimal for cost-sensitive, high-volume power conversion where algorithm footprint fits within 128KB.
