Product details
Overview
TMS320F280041PZQR from Texas Instruments is a 100MHz C28x-based real-time MCU with IEEE 754 FPU, CLA accelerator, 128KB flash, 100KB RAM, and integrated analog (3× 12-bit 3.45MSPS ADCs, 7 PGAs, 7 CMPSS) for high-precision motor control in EV charging power modules and solar inverters.
For engineers reviewing the TMS320F280041PZQR datasheet, TMS320F280041PZQR pinout, TMS320F280041PZQR application, or TMS320F280041PZQR equivalent, key selection criteria include functional safety support (FS-QM), 16-channel ePWM with 150ps resolution, dual CAN interfaces, InstaSPIN-FOC™ ROM library, and 100-pin LQFP package compatibility with industrial thermal requirements (–40°C to 125°C).
Technical Context
The TMS320F280041PZQR implements a dual-core real-time control architecture: a 100MHz C28x CPU with TMU/VCU-I for fast trigonometric and complex math, plus an independent 100MHz CLA executing floating-point control loops without CPU intervention. Its analog subsystem integrates three synchronized 12-bit ADCs with four post-processing blocks per ADC and seven PGA channels supporting gain settings of 3/6/12/24.
System-level timing is managed via two internal zero-pin oscillators, windowed watchdog, and missing-clock detection. Peripheral connectivity includes two CAN 2.0B ports, two SPI, two SCI, one I²C, one LIN, one PMBus, and one FSI interface - all pin-bootable and multiplexed across 40 GPIOs in the 100-pin PZ package.
Key Specifications

FAQ
What is the maximum operating junction temperature for the TMS320F280041PZQR?
The TMS320F280041PZQR is rated for a junction temperature range of –40°C to 125°C, meeting industrial and automotive ambient requirements. This specification is validated per TI's characterization and aligns with the device's qualification under AEC Q100 Grade 1 conditions, enabling use in convection-cooled power modules without forced airflow.
Does the TMS320F280041PZQR include a hardware CLA accelerator?
Yes, the TMS320F280041PZQR includes a fully functional Control Law Accelerator (CLA) operating at 100MHz with IEEE 754 single-precision floating-point support. It executes independently of the main C28x CPU, accesses shared peripherals directly, and supports ANSI C subset programming - confirmed in TI's SPRS945H datasheet Section 7.7.
Is InstaSPIN-FOC™ supported on the TMS320F280041PZQR?
No, InstaSPIN-FOC™ is not supported on the TMS320F280041PZQR. That feature is exclusive to 'C'-suffix variants (e.g., TMS320F280041C-PZQR) which include secured ROM containing the InstaSPIN library. The TMS320F280041PZQR lacks this ROM and CLB access, as documented in TI's Device Comparison Table (Section 4.1).
What analog peripherals are integrated into the TMS320F280041PZQR?
The TMS320F280041PZQR integrates three 12-bit 3.45MSPS ADCs with 21 external input channels, seven programmable gain amplifiers (PGA) with selectable gains of 3/6/12/24, seven windowed comparators (CMPSS) each with 12-bit DAC references, two buffered DAC outputs, and four sigma-delta filter module (SDFM) input channels - all detailed in Sections 6.10 and 4.1 of SPRS945H.
How many CAN interfaces does the TMS320F280041PZQR support?
The TMS320F280041PZQR supports two Controller Area Network (CAN) 2.0B interfaces, both pin-bootable and independently configurable. These are implemented as CANA and CANB modules with dedicated H/L terminals, enabling dual-bus architectures for redundancy or subsystem segmentation in EV charging and energy storage applications.
