Product details
Overview
F280037SPM 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 16-channel ePWM with 150-ps high-resolution capability. It supports CAN FD, FSI (200 Mbps), and CLA acceleration for motor drives and digital power conversion.
For engineers reviewing the F280037SPM datasheet, F280037SPM pinout, F280037SPM application, or F280037SPM equivalent, key selection criteria include its 64-pin LQFP (PM) package, dual-zone security, functional safety compliance (ASIL B/SIL 2), and support for GaN/SiC gate drive timing in servo and inverter systems.
Technical Context
The F280037SPM implements a dual-core real-time architecture: the main C28x CPU executes at 120 MHz with FPU, TMU, and VCRC extensions for fast trigonometric and CRC-intensive control loops, while the independent CLA runs parallel floating-point tasks at 120 MHz with dedicated memory and direct peripheral access. Both cores share a unified bus architecture with ERAD and ePIE for deterministic interrupt handling.
Its analog subsystem integrates three 4-MSPS 12-bit ADCs with 250-ns conversion time, four CMPSS modules with 12-bit DAC references, two buffered DAC outputs, and eight SDFM channels - tightly coupled to ePWM and eCAP for closed-loop current/voltage sensing and fast overcurrent response in switching power stages.

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F280037C | Same core, CLA, CLB, and peripherals; differs only in flash configuration (256KB vs. F280037SPM's 256KB) and package marking-identical electrical and timing behavior | Identical use cases; no functional divergence in motor control, digital power, or EV charging | Select F2800037C when standard commercial-grade qualification suffices and AEC-Q100 is not required |
| TMS320F280036C-Q1 | 128KB flash (vs. 256KB), no CLB, same 64-pin PM package and ASIL B/SIL 2 certification; retains CLA, FPU, and 16-channel ePWM | Targeted at cost-sensitive automotive body control and low-complexity EPS where logic augmentation is unnecessary | Choose F280036C-Q1 for AEC-Q100-compliant designs with reduced memory and no CLB requirement |
Compared with F280037C, the F280037SPM offers identical functionality and qualification but is designated for specific distribution channels; versus F280036C-Q1, it adds CLB and doubles flash-enabling complex position manager solutions and dual-firmware storage for LFU in mission-critical inverters.

What is the maximum operating junction temperature for the F280037SPM?
The F280037SPM has a specified junction temperature range of –40°C to 150°C per TI's SPRSP61C datasheet. This rating applies to all 64-pin PM package variants, including F280037SPM, and enables operation in high-thermal-load environments such as enclosed EV charger modules and industrial servo drives without forced cooling.
Does the F280037SPM support CAN FD communication?
Yes, the F280037SPM includes one Controller Area Network with Flexible Data-Rate (CAN FD/MCAN) port compliant with ISO 11898-1:2015, supporting data rates up to 5 Mbps and payloads up to 64 bytes. This interface is fully accessible on the 64-pin PM package and is used for high-bandwidth diagnostics and control messaging in automotive and industrial networks.
How many high-resolution PWM channels does the F280037SPM provide?
The F280037SPM provides eight high-resolution ePWM channels (ePWM1–ePWM4, each with A/B outputs) capable of 150-ps resolution, integrated dead-band generation, and hardware trip-zone protection. These channels are fully functional in the 64-pin PM package and are essential for precise gate timing in SiC and GaN half-bridge topologies.
Is the F280037SPM pin-compatible with other TMS320F28003x devices in the 64-pin PM package?
Yes, the F280037SPM shares identical pinout, electrical characteristics, and package dimensions with all other TMS320F28003x variants offered in the 64-pin PM LQFP package-including F280037C, F280037C-Q1, and F280037-Q1-ensuring drop-in compatibility for layout reuse and qualification migration.
