Product details
Overview
TMS320F280049PZQR from Texas Instruments is a functional-safety-compliant 32-bit real-time microcontroller featuring a 100MHz C28x CPU, IEEE 754 FPU, Trigonometric Math Unit (TMU), and a 100MHz Control Law Accelerator (CLA). It integrates 256KB ECC-protected 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.
For engineers reviewing the TMS320F280049PZQR datasheet, TMS320F280049PZQR pinout, TMS320F280049PZQR application, or TMS320F280049PZQR equivalent, key selection considerations include ASIL B functional safety certification, CLA offloading capability for real-time torque loop execution, 100-pin LQFP package with 40 GPIOs and 21 analog inputs, and InstaSPIN-FOC™ ROM library support for sensorless field-oriented control.
Technical Context
The TMS320F280049PZQR implements a dual-core real-time control architecture: the main C28x CPU handles system orchestration and communication, while the independent CLA executes time-critical control algorithms-including Park transforms in 13 cycles and trigonometric functions at 3×–4× software speed-without CPU intervention. Both cores share access to on-chip memory and peripherals via a unified bus matrix.
Its analog subsystem includes three synchronized 12-bit ADCs with 290ns conversion time, seven PGAs (gain settings: 3/6/12/24), seven windowed comparators with integrated 12-bit DAC references, and four SDFM input channels for sigma-delta modulator interfacing. The device supports AEC Q100 Grade 1 qualification (–40°C to +125°C free-air) and ISO 26262 ASIL B certification by TÜV SÜD.

FAQ
What is the functional safety status of the TMS320F280049PZQR?
The TMS320F280049PZQR is ISO 26262 ASIL B certified by TÜV SÜD and supports systematic capability up to ASIL D. It includes hardware safety features such as ECC memory, dual-zone security, ERAD debug, and documented failure modes for use in automotive and industrial safety-critical systems. The TMS320F280049PZQR Functional Safety Manual and certification reports are available from TI.
Does the TMS320F280049PZQR support InstaSPIN-FOC™ out of the box?
Yes, the TMS320F280049PZQR includes the InstaSPIN-FOC™ library pre-programmed in on-chip ROM memory. This enables immediate deployment of sensorless field-oriented control without external flash programming or licensing. The TMS320F280049PZQR leverages its CLA and TMU to execute FAST™ observer algorithms in real time, reducing development time for BLDC and PMSM motor drives.
What package and pin count does the TMS320F280049PZQR use?
The TMS320F280049PZQR uses a 100-pin Low-profile Quad Flatpack (LQFP) package with 0.5mm pitch and 14mm × 14mm body size. It provides 40 GPIOs, 21 analog input channels, dual CAN, two SPI, two SCI, I²C, LIN, PMBus, FSI, and full access to all 16 ePWM channels and three ADCs - matching the maximum peripheral count for the F28004x family.
How does the CLA in the TMS320F280049PZQR improve real-time performance?
The CLA in the TMS320F280049PZQR is a fully autonomous 32-bit floating-point accelerator running at 100MHz, executing control loops in parallel with the main C28x CPU. It directly accesses peripherals like ePWM and ADC, enabling sub-microsecond response to current faults or position errors. This offloading allows the CPU to handle communications and diagnostics while the CLA maintains deterministic torque loop execution - critical for TMS320F280049PZQR-based servo and inverter designs.
Can the TMS320F280049PZQR replace the TMS320F280049C in an existing design?
Yes, the TMS320F280049PZQR is pin-compatible and functionally identical to the TMS320F280049C, with the added benefit of AEC Q100 qualification and ASIL B certification. No PCB or firmware changes are required for migration; however, users must adopt TI's functional safety documentation package and follow safety configuration guidelines to leverage the certified capabilities of the TMS320F280049PZQR.
