Overview
TMS320F280041PZSR from Texas Instruments is a 100MHz C28x-based real-time MCU with IEEE 754 FPU, CLA accelerator, 128KB flash, 100KB RAM (ECC/parity-protected), and 40 GPIOs - designed for high-precision motor control in solar inverters, EV charging power modules, and industrial AC drives.
For engineers reviewing the TMS320F280041PZSR datasheet, TMS320F280041PZSR pinout, TMS320F280041PZSR application, or TMS320F280041PZSR equivalent, key selection factors include its 16-channel ePWM with 150ps resolution, three 3.45MSPS 12-bit ADCs, dual CAN interfaces, functional safety quality-managed status, and 100-pin LQFP package with analog input support on 21 pins.
Technical Context
The TMS320F280041PZSR integrates a C28x CPU core running at 100MHz with hardware-accelerated trigonometric (TMU) and complex math (VCU-I) units, enabling sub-13-cycle Park transforms and 3×–4× speedup over software libraries. Its independent CLA executes floating-point control loops in parallel with the main CPU.
It features three synchronized 12-bit ADCs (3.45MSPS each), seven PGA inputs with gain settings of 3/6/12/24, seven windowed comparators with integrated 12-bit DAC references, and four SDFM channels for sigma-delta modulator interfacing - all supporting closed-loop timing-critical control in power electronics.

The TMS320F280041PZSR features a C28x 32-bit CPU core rated for 100MHz operation under full temperature and voltage specifications. This frequency enables deterministic execution of complex control algorithms such as field-oriented control (FOC) and model-predictive control (MPC) within tight timing budgets required for high-switching-frequency power converters.
Does the TMS320F280041PZSR include hardware safety features for industrial applications?
The TMS320F280041PZSR is designated as Functional Safety Quality-Managed (FS-QM) per TI's documentation. It includes hardware features such as ECC-protected flash and RAM, windowed watchdog timer, missing clock detection, and brownout reset - supporting system-level ISO 26262 ASIL B or IEC 61508 SIL 3 compliance when implemented with appropriate software and system design.
How many analog input channels does the TMS320F280041PZSR support in its 100-pin LQFP package?
In the 100-pin LQFP (PZ) package, the TMS320F280041PZSR supports up to 21 external analog input channels across its three 12-bit ADCs. Additionally, seven PGA inputs provide programmable gain (3/6/12/24) for signal conditioning prior to ADC conversion - enabling direct connection of shunt-based current sensors and isolated voltage dividers.
Is the TMS320F280041PZSR pin-compatible with other devices in the F28004x family?
Yes - the TMS320F280041PZSR shares identical pinout and footprint with other 100-pin PZ variants in the F28004x family, including TMS320F280049PZSR and TMS320F280045PZSR. This allows hardware reuse across performance tiers, though firmware must account for differences in flash size, CLB availability, and ROM content (e.g., InstaSPIN-FOC™).
What communication interfaces are available on the TMS320F280041PZSR for grid-tied inverter applications?
The TMS320F280041PZSR provides two CAN interfaces (CAN0/CAN1), two UART-compatible SCIs, one PMBus port, and one Fast Serial Interface (FSI) - making it suitable for grid-tied inverter applications requiring redundant communication to energy management systems, grid relays, and auxiliary controllers while maintaining isolation boundaries.
