Texas Instruments F280039CSPMR

Overview

F280039CSPMR from Texas Instruments is a C28x-based real-time microcontroller with 120 MHz DSP core, IEEE 754 FPU, CLA accelerator, 384KB ECC-protected flash, and 69KB ECC-protected RAM. It integrates three 4-MSPS 12-bit ADCs, 16 ePWM channels (8 with 150-ps resolution), dual CAN/CAN FD interfaces, FSI up to 200 Mbps, and CLB for FPGA-like logic - deployed in servo drives, solar inverters, and EV on-board chargers.

For engineers reviewing the F280039CSPMR datasheet, F280039CSPMR pinout, F280039CSPMR application, or F280039CSPMR equivalent, key selection criteria include CLA offload capability, 150-ps HRPWM timing precision, functional safety compliance (ASIL B/SIL 2), dual CAN FD + DCAN support, and 100-pin LQFP package thermal performance at 150°C junction temperature.

Technical Context

The F280039CSPMR implements a dual-core real-time control architecture: the C28x CPU executes deterministic floating-point control loops at 120 MHz with TMU and VCRC acceleration, while the independent CLA runs parallel 120 MHz floating-point tasks using dedicated message RAM and direct peripheral access. Both cores share ECC-protected memory and synchronize via hardware mailbox.

Its analog subsystem tightly couples three 4-MSPS ADCs with four CMPSS modules (each with 12-bit DAC references) and two buffered DAC outputs, enabling closed-loop current/voltage sensing and fast overvoltage trip response. The 16-channel ePWM includes integrated dead-band, hardware trip zones, and high-resolution capability on eight channels - critical for GaN/SiC gate drive timing accuracy.

FAQ

What is the maximum operating junction temperature for the F280039CSPMR?

The F280039CSPMR supports a junction temperature range of –40°C to 150°C, validated per TI's thermal resistance characteristics for the 100-pin PZ LQFP package. This rating enables deployment in high-ambient environments such as under-hood automotive power modules or enclosed industrial inverters without derating, provided board-level thermal design meets recommended copper pour and airflow guidelines specified in the datasheet.

Does the F280039CSPMR support functional safety certification out of the box?

Yes, the F280039CSPMR (PZ package) is ISO 26262 ASIL B and IEC 61508 SIL 2 certified by TÜV SÜD. Certification applies to the silicon, safety manual, FMEDA report, and diagnostic software library - all available through TI's functional safety resource center. No additional hardware modifications are required to achieve this level of systematic and hardware capability.

How many high-resolution PWM channels does the F280039CSPMR provide?

The F280039CSPMR provides eight high-resolution PWM channels (ePWM1–ePWM4 A/B pairs), each capable of 150-ps resolution for precise gate driver timing. These channels support independent frequency, duty cycle, and phase control, and integrate hardware trip zones, dead-band generation, and event synchronization - essential for SiC/GaN half-bridge and multilevel topologies.

Can the F280039CSPMR execute firmware updates without interrupting real-time control?

Yes, the F280039CSPMR supports Live Firmware Update (LFU) with zero-downtime context switching between active and standby flash banks. Its three-bank flash architecture allows background erase and programming while executing from another bank, and hardware-assisted bank swapping minimizes transition latency to under 1 µs - preserving motor torque continuity and power stage stability during updates.

What analog peripherals are integrated into the F280039CSPMR?

The F280039CSPMR integrates three independent 12-bit 4-MSPS ADCs with up to 25 external channels, four windowed comparators (CMPSS) with integrated 12-bit DAC references, two buffered DAC outputs, and eight Sigma-Delta Filter Module (SDFM) input channels. These peripherals are synchronized and low-latency-coupled to ePWM and CLA for real-time current sensing, overvoltage protection, and sensorless motor control.
