Texas Instruments TMS320F28374SPTPT

Overview

TMS320F28374SPTPT from Texas Instruments is a 32-bit floating-point real-time microcontroller with a 200MHz C28x CPU, IEEE 754 FPU, Trigonometric Math Unit (TMU), and Viterbi/Complex Math Unit (VCU-II), integrated into a 176-pin HLQFP package rated for –40°C to 125°C junction temperature. It delivers deterministic control for high-precision motor drives and digital power conversion.

For engineers reviewing the TMS320F28374SPTPT datasheet, TMS320F28374SPTPT pinout, TMS320F28374SPTPT application, or TMS320F28374SPTPT equivalent, key selection criteria include its single-CPU/CLA subsystem architecture, 512KB flash + 132KB RAM memory configuration, dual CAN interfaces, four 16-/12-bit ADCs (up to 4.4MSPS aggregate), and 24-channel ePWM with 16 high-resolution channels.

Technical Context

The TMS320F28374SPTPT implements a single-core C28x CPU + CLA coprocessor architecture-both running at 200MHz-with hardware accelerators (TMU, VCU-II) optimized for real-time torque loop and field-oriented control math. Its analog subsystem includes four independent ADCs supporting simultaneous 16-bit (1.1MSPS each) or 12-bit (3.5MSPS each) sampling, plus eight SDFM input channels for isolated current sensing.

Control peripherals include 24 ePWM channels (16 HRPWM-capable), six eCAP modules, three eQEP modules, and a Configurable Logic Block (CLB) for position manager augmentation. Communications are supported via two CAN 2.0B modules, four SCIs, three SPIs, two I2Cs, one USB 2.0 (MAC+PHY), and one uPP interface-all pin-bootable.

FAQ

What is the maximum operating junction temperature for the TMS320F28374SPTPT?

The TMS320F28374SPTPT is rated for a maximum junction temperature of 125°C, as indicated by the 'S' temperature grade suffix. This rating applies across the full operating voltage range and supports deployment in demanding industrial and automotive under-hood environments without derating when proper thermal design (e.g., PCB copper pour, thermal vias) is implemented for the PTP package's PowerPAD.

Does the TMS320F28374SPTPT support hardware-based functional safety certification?

Yes, the TMS320F28374SPTPT is ISO 26262 ASIL B and IEC 61508 SIL 2 certified by TÜV SÜD. It includes hardware integrity features such as ECC on flash and RAM, windowed watchdog timers, missing-clock detection, and hardware BIST - all documented to support safety-related system development up to these levels.

How many high-resolution PWM channels does the TMS320F28374SPTPT provide?

The TMS320F28374SPTPT provides 16 high-resolution PWM (HRPWM) channels, distributed across eight ePWM modules where both A and B outputs support HRPWM capability. Each channel achieves 150ps resolution and supports independent dead-band generation - essential for SiC and GaN gate driver timing precision.

Can the TMS320F28374SPTPT execute code independently on its CLA coprocessor?

Yes, the TMS320F28374SPTPT includes a fully autonomous Control Law Accelerator (CLA) that runs IEEE 754 single-precision floating-point code at 200MHz, triggered by peripheral events (e.g., ADC end-of-conversion, PWM timer overflow). The CLA operates concurrently with the main C28x CPU and uses dedicated message RAM for inter-processor communication - enabling true parallel real-time control execution.

What analog-to-digital converter configurations are supported by the TMS320F28374SPTPT?

The TMS320F28374SPTPT integrates four independent ADCs configurable in 16-bit mode (1.1MSPS each, differential inputs, up to 12 external channels) or 12-bit mode (3.5MSPS each, single-ended inputs, up to 24 external channels). All ADCs include hardware post-processing features including offset calibration, windowed compare, and trigger-to-sample delay capture - reducing CPU overhead in sensor acquisition.
