Product details
Overview
TMS320F280041PMS from Texas Instruments is a 32-bit real-time microcontroller optimized for high-precision motor control and digital power conversion, featuring a 100MHz C28x CPU with IEEE 754 FPU, 128KB flash (ECC-protected), 100KB RAM (ECC/parity-protected), and integrated analog subsystem including three 3.45MSPS 12-bit ADCs and seven PGAs - deployed in EV charging station power modules and solar string inverters.
For engineers reviewing the TMS320F280041PMS datasheet, TMS320F280041PMS pinout, TMS320F280041PMS application, or TMS320F280041PMS equivalent, key selection criteria include CLA acceleration for torque-loop offload, ePWM with 150ps resolution for high-fidelity gate timing, functional safety documentation support up to ASIL B, and compatibility with InstaSPIN-FOC™ library in ROM for sensorless FOC deployment.
Technical Context
The TMS320F280041PMS implements a dual-core real-time control architecture: the main C28x CPU executes at 100MHz with TMU and VCU-I extensions for fast trigonometric and complex math, while the independent CLA runs parallel floating-point code at 100MHz with dedicated memory and direct peripheral access. Both cores share a unified bus architecture supporting deterministic interrupt latency via ePIE.
Its analog subsystem integrates three synchronized 12-bit ADCs (3.45MSPS each), seven PGA channels (gain settings 3/6/12/24), seven windowed comparators with 12-bit DAC references, and four SDFM input channels - enabling simultaneous current/voltage sensing, overcurrent trip detection, and sigma-delta modulator interfacing across isolation barriers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | C28x 32-bit DSP core @ 100MHz with IEEE 754 FPU, TMU, and VCU-I - enables real-time execution of Park/Clarke transforms and field-oriented control loops without software libraries. |
| CLA | Independent 32-bit floating-point accelerator @ 100MHz - offloads time-critical control tasks (e.g., current regulation) from CPU, reducing main loop latency by up to 4×. |
| Flash / RAM | 128KB (64KW) ECC-protected flash across single bank; 100KB (50KW) RAM (ECC/parity-protected) - supports secure firmware updates and robust runtime data integrity in industrial environments. |
| Analog Subsystem | Three 12-bit ADCs @ 3.45MSPS (290ns conversion time); 7 PGA inputs (gain 3/6/12/24); 7 CMPSS with 12-bit DAC references - enables high-resolution, low-latency analog signal conditioning for dual-shunt motor current sensing. |
| ePWM / HRPWM | 16 channels with 150ps high-resolution period control and integrated dead-band generation - delivers precise, jitter-free gate drive timing for SiC/GaN half-bridges in DC/DC and inverter stages. |
| Package & Temp | 64-pin LQFP (PM suffix), –40°C to 125°C junction temperature - suitable for convection-cooled power electronics enclosures without forced airflow. |
