Product details
Overview
TMS320F280041RSHSR from Texas Instruments is a 100MHz C28x 32-bit floating-point real-time MCU with IEEE 754 FPU, CLA accelerator, 128KB flash, 100KB RAM (ECC/parity-protected), and 56-pin VQFN package. It integrates three 3.45MSPS 12-bit ADCs, seven PGAs, dual CAN, FSI, and ePWM with 150ps resolution-designed for high-precision motor control in EV charging power modules.
For engineers reviewing the TMS320F280041RSHSR datasheet, TMS320F280041RSHSR pinout, TMS320F280041RSHSR application, or TMS320F280041RSHSR equivalent, key selection criteria include functional safety support (FS-QM), CLA offload capability, analog front-end channel count (12 external ADC channels, 4 PGA inputs), and VQFN-56 thermal performance in space-constrained industrial power converters.
Technical Context
The TMS320F280041RSHSR implements a dual-core real-time control architecture: the 100MHz C28x CPU handles main-loop execution and system management, while the independent 100MHz CLA executes time-critical control tasks-including Park/Clarke transforms and PID updates-without CPU intervention. Both cores share access to on-chip memory and peripherals via a unified bus matrix.
Its analog subsystem features three synchronized 12-bit ADCs (3.45MSPS aggregate), each with four post-processing blocks (PPBs), plus seven windowed comparators with integrated 12-bit DAC references and five programmable-gain amplifiers (gain settings: 3/6/12/24). The 56-pin RSH package exposes 25 GPIOs, 12 analog inputs, and dedicated pins for FSI, CAN, SPI, and ePWM outputs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time motor control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F280049RSHR | 256KB flash, CLB enabled, InstaSPIN-FOC™ ROM - higher memory and logic resources. | Required for complex multi-axis servo systems or designs needing CLB-based encoder interpolation. | Select when >128KB flash or CLB functionality is needed; otherwise TMS320F280041RSHSR offers optimal cost/performance balance. |
| TMS320F280025CRSBR | 100MHz C28x, 64KB flash, no CLA, no TMU/VCU-I, 48-pin VQFN - lower-cost entry-tier variant. | Suitable for simpler single-phase inverters or fans where trigonometric acceleration and dual CAN are not required. | Choose for cost-sensitive, lower-complexity applications; lacks CLA, TMU, and analog channel count for advanced motor control. |
Compared with TMS320F280049RSHR, the TMS320F280041RSHSR reduces flash size and omits CLB but retains identical CPU, FPU, ADC, and PWM specs-making it ideal for optimized single-axis control.
