Texas Instruments F280037SPN

Overview

F280037SPN from Texas Instruments is a C28x-based real-time microcontroller designed for high-efficiency power electronics control, featuring a 120-MHz TMS320C28x DSP core with IEEE 754 FPU, 256KB ECC-protected flash, 69KB ECC-protected RAM, and integrated analog peripherals including three 4-MSPS 12-bit ADCs and 16 ePWM channels with 150-ps high-resolution capability. It targets motor drives, solar inverters, and EV charging power stages.

For engineers reviewing the F280037SPN datasheet, F280037SPN pinout, F280037SPN application, or F280037SPN equivalent, key selection criteria include CLA acceleration support, CLB configurability, CAN FD + DCAN dual-bus capability, functional safety compliance (ASIL B/SIL 2), and LQFP-80 package compatibility with 39 GPIO pins and 18 ADC channels.

Technical Context

The F280037SPN implements a dual-core real-time architecture: the main C28x CPU runs at 120 MHz with FPU, TMU, and VCRC extensions for fast trigonometric and CRC-intensive control loops, while the independent CLA executes floating-point math in parallel at 120 MHz-enabling deterministic execution of critical PWM timing and current-loop tasks without CPU intervention.

Its analog subsystem tightly couples three 4-MSPS ADCs with four CMPSS modules (each with 12-bit DAC references) and two buffered DAC outputs, supporting simultaneous sampling and hardware-triggered post-processing for closed-loop motor phase current sensing and voltage regulation in GaN/SiC-based power stages.

FAQ

What is the maximum operating junction temperature for the F280037SPN?

The F280037SPN has a specified junction temperature range of –40°C to 150°C, enabling reliable operation in high-power-density applications such as onboard chargers and industrial motor drives where thermal management is critical. This rating applies to all F280037 variants, including the F280037SPN in the 80-pin PN package.

Does the F280037SPN support CAN FD communication?

Yes, the F280037SPN integrates a dedicated MCAN module supporting Controller Area Network with Flexible Data-Rate (CAN FD), enabling data rates up to 5 Mbps and payloads up to 64 bytes. This complements its separate DCAN port (CAN 2.0B), allowing simultaneous legacy and high-speed automotive or industrial network communication without external transceivers.

How many high-resolution PWM channels does the F280037SPN provide?

The F280037SPN provides eight high-resolution ePWM channels (EPWM1–EPWM4 A/B pairs), each capable of 150-ps resolution for precise dead-time insertion, phase shifting, and gate driver timing-critical for minimizing switching losses in SiC and GaN power stages. All 16 ePWM channels are accessible in the 80-pin PN package.

Is the CLA (Control Law Accelerator) available on the F280037SPN?

Yes, the F280037SPN includes a fully functional CLA running at 120 MHz, supporting IEEE 754 single-precision floating-point instructions and executing independently of the main C28x CPU. It accesses dedicated message RAM and directly controls key peripherals like ePWM and ADC, enabling deterministic real-time loop execution in motor and power control applications.

What analog-to-digital converter (ADC) performance does the F280037SPN deliver?

The F280037SPN integrates three 12-bit ADCs operating at 4 MSPS each, with hardware synchronization and up to 18 external single-ended input channels in the 80-pin PN package. Each ADC includes four post-processing blocks (PPB) for real-time averaging, offset correction, and filtering-reducing software overhead in current-sensing and voltage-monitoring loops.
