Product details
Overview
F280040CPMQR from Texas Instruments is a 100MHz C28x-based real-time microcontroller with IEEE 754 FPU, CLA accelerator, 128KB flash, 100KB RAM, and integrated analog peripherals including three 3.45MSPS 12-bit ADCs and seven PGAs - deployed in EV charging power modules and solar string inverters.
For engineers reviewing the F280040CPMQR datasheet, F280040CPMQR pinout, F280040CPMQR application, or F280040CPMQR equivalent, key selection factors include its 64-pin LQFP package, Q-temperature grade (–40°C to 125°C), CLA-enabled deterministic control loop offload, InstaSPIN-FOC™ ROM support, and functional safety quality-managed status per ISO 26262 ASIL B certification scope.
Technical Context
The F280040CPMQR 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 tasks without CPU intervention. Its analog subsystem integrates three synchronized 12-bit ADCs with 290ns conversion time and four post-processing blocks per ADC.
Control peripherals include 16 ePWM channels with 150ps high-resolution capability, seven eCAP modules (two with HRCAP), two eQEP interfaces, and four SDFM input channels. Communication is supported via dual CAN, two SPI, two SCI, I²C, LIN, PMBus, and FSI - all pin-muxed on 26 GPIOs in the 64-pin PM package.

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| F280041CPMQR | 128KB flash, same CLA/PGA/ADC specs, includes CLB and InstaSPIN-FOC™ ROM | Identical package and temperature grade; adds CLB for custom logic and InstaSPIN for sensorless motor control | Select when requiring on-chip position estimation or hardware-accelerated interface logic beyond base F280040C capabilities. |
| F280040PMQR | No CLB, no InstaSPIN-FOC™ ROM, same 128KB flash and analog/peripheral set | Same Q-grade 64-pin LQFP package but lacks CLB tiles and ROM-based motor control library | Choose for cost-sensitive industrial power supplies where CLB and sensorless FOC are not required. |

FAQ
What is the functional safety status of the F280040CPMQR?
The F280040CPMQR is designated Functional Safety Quality-Managed (FS-QM) per TI's documentation. It follows ISO 26262 ASIL B development processes and provides safety manuals and diagnostic coverage data, but is not itself certified to ASIL B - unlike F280048CPMQR or F280049CPZQR listed in TI's functional safety table. The F280040CPMQR supports system-level safety design when used with appropriate diagnostics and fault handling.
Does the F280040CPMQR include the Configurable Logic Block (CLB)?
Yes, the F280040CPMQR includes a 4-tile Configurable Logic Block (CLB), as confirmed in TI's Device Comparison Table (Table 4-1). This CLB enables hardware implementation of custom logic for encoder interfaces, protection state machines, or position manager functions - augmenting standard peripherals without CPU intervention.
What analog features distinguish the F280040CPMQR from earlier C2000 MCUs?
The F280040CPMQR integrates three independent 12-bit ADCs operating at 3.45MSPS with 290ns conversion time, seven programmable gain amplifiers (3/6/12/24×), seven windowed comparators with integrated 12-bit DAC references, and two buffered DAC outputs. These features exceed F28002x and F28003x generations in simultaneous channel count, PGA integration, and comparator response speed - optimized for multi-sensor power stage monitoring.
Which communication interfaces are available on the F280040CPMQR in the 64-pin PM package?
In the 64-pin LQFP (PM) package, the F280040CPMQR supports two CAN ports, two SPI interfaces, two UART-compatible SCIs, one I²C, one LIN, one PMBus, and one Fast Serial Interface (FSI). All are pin-muxed across its 26 GPIOs, with specific pin assignments documented in TI SPRS945H Figure 5-3 for the Q-temperature variant.
How does the Control Law Accelerator (CLA) in the F280040CPMQR improve real-time performance?
The CLA in the F280040CPMQR is a fully independent 100MHz 32-bit floating-point accelerator that executes control code in parallel with the main C28x CPU. It accesses dedicated RAM and key peripherals directly, enabling sub-microsecond PID updates, observer calculations, and PWM update tasks - reducing CPU load by up to 40% in high-frequency motor control applications and improving loop determinism.
