Texas Instruments F280037CSPM

Overview

F280037CSPM from Texas Instruments is a C28x-based real-time microcontroller designed for high-precision power electronics control, featuring a 120-MHz DSP core with IEEE 754 FPU, 256KB ECC-protected flash, 69KB ECC-protected RAM, and integrated analog subsystem including three 4-MSPS 12-bit ADCs and 16 ePWM channels with 150-ps high-resolution capability.

For engineers reviewing the F280037CSPM datasheet, F280037CSPM pinout, F280037CSPM application, or F280037CSPM equivalent, key selection criteria include CLA acceleration for independent control-loop execution, CLB support for FPGA-like logic augmentation, CAN FD and FSI (200 Mbps) for robust isolation-capable communication, and functional safety readiness (ASIL B/SIL 2) in qualified packages.

Technical Context

The F280037CSPM implements a dual-core real-time architecture: the C28x CPU executes at 120 MHz with FPU, TMU, and VCRC extensions for fast trigonometric and CRC-intensive control math, while the independent CLA runs parallel floating-point tasks using dedicated memory and direct peripheral access. Both cores share a unified bus architecture with ERAD debug and hardware breakpoint support.

Its analog signal chain tightly couples three 12-bit ADCs (4 MSPS each, up to 25 external channels), four CMPSS modules with 12-bit DAC references, two buffered DAC outputs, and eight SDFM input channels - all synchronized to 16 ePWM outputs with integrated dead-band and hardware trip zones for GaN/SiC gate driver timing integrity.

Equivalent & Alternatives

The following parts are listed as comparable options for similar real-time control applications.

Compared with TMS320F280039C, F280037CSPM trades 128KB flash for identical real-time performance and CLB capability in the same 64-pin footprint; versus F280034, it adds CLB, doubles flash, and retains full peripheral access-making it optimal for mid-tier GaN/SiC power converters requiring FPGA-like logic but not maximum memory.

FAQ

What is the maximum operating frequency of the C28x CPU in the F280037CSPM?

The C28x CPU in the F280037CSPM operates at a maximum frequency of 120 MHz. This clock speed applies to both integer and IEEE 754 single-precision floating-point instruction execution. The F280037CSPM achieves this performance using an internal PLL driven by either the 10-MHz internal oscillator or an external crystal/clock source, with full support for dynamic frequency scaling during low-power modes.

Does the F280037CSPM support functional safety certification out of the box?

The F280037CSPM itself is not certified; however, the PM package variant (F280037CSPM) is qualified under AEC-Q100 Grade 1 and supports ISO 26262 ASIL B and IEC 61508 SIL 2 system-level certification when used with TI's safety documentation package. Certification requires proper implementation of diagnostic features like MPOST, HWBIST, and ERAD, and adherence to TI's safety manual guidelines for the F280037CSPM device.

How many high-resolution PWM channels does the F280037CSPM support?

The F280037CSPM supports eight high-resolution PWM channels - specifically EPWM1 through EPWM4, each providing complementary A/B outputs with 150-ps resolution. These channels enable precise timing control for GaN and SiC power devices, including programmable dead-time insertion, hardware trip-zone protection, and synchronization with ADC sampling windows for current reconstruction.

What analog-to-digital converter (ADC) performance does the F280037CSPM deliver?

The F280037CSPM integrates three independent 12-bit ADCs, each capable of 4 million samples per second (4 MSPS). Each ADC supports up to 25 single-ended input channels (including two gpdac outputs), features four post-processing blocks (PPBs) for real-time filtering, and provides <100-ns inter-channel sampling skew. Conversion time is 250 ns per sample, enabling accurate current/voltage measurement in high-frequency power topologies.

Can the F280037CSPM execute control algorithms independently of the main CPU?

Yes, the F280037CSPM includes a dedicated Control Law Accelerator (CLA) that runs at 120 MHz and executes floating-point control code independently of the main C28x CPU. The CLA has its own program/data RAM, direct peripheral access, and hardware task-switching - allowing time-critical loops (e.g., FOC, MPPT) to run concurrently without CPU scheduling overhead or interrupt latency.
