Product details
Overview
TMS320F28379SPTPT from Texas Instruments is a high-performance 32-bit floating-point real-time microcontroller featuring a 200MHz C28x CPU, IEEE 754 FPU, Trigonometric Math Unit (TMU), Viterbi/Complex Math Unit (VCU-II), and a parallel 200MHz Control Law Accelerator (CLA). It integrates 1MB flash (ECC-protected), 164KB RAM (ECC/parity-protected), four 16-/12-bit ADCs (up to 4.4MSPS system throughput), 24 ePWM channels with 16 HRPWMs, dual CAN, USB 2.0, and CLB for industrial motor control and solar inverter applications.
For engineers reviewing the TMS320F28379SPTPT datasheet, TMS320F28379SPTPT pinout, TMS320F28379SPTPT application, or TMS320F28379SPTPT equivalent, key selection criteria include dual-zone security, ASIL B/SIL 2 functional safety certification, 176-pin HLQFP package with thermal pad, 169 GPIOs, and support for closed-loop control in traction inverters and EV charging power modules.
Technical Context
The TMS320F28379SPTPT implements a single-CPU + single-CLA architecture (vs. dual-CPU F2837xD), enabling deterministic real-time control where the CLA offloads time-critical tasks like PWM update or ADC post-processing while the C28x CPU handles communications and diagnostics. Its analog subsystem includes four independent ADCs with hardware-accelerated post-processing (windowed comparators, DAC-referenced thresholds, error-from-setpoint calculation) and eight SDFM input channels for isolated current sensing.
System-level integration is enhanced by two EMIFs (ASRAM/SDRAM), six-channel DMA, configurable logic block (CLB) with four tiles for position manager augmentation, and safety-critical peripherals including windowed watchdog, missing-clock detection, and dual-code security module with OTP and secure boot ROM. The device operates at 1.2V core / 3.3V I/O across –40°C to 125°C junction temperature.

FAQ
What is the maximum operating junction temperature for the TMS320F28379SPTPT?
The TMS320F28379SPTPT is rated for a junction temperature range of –40°C to 125°C, indicated by the 'S' suffix in its part number. This extended temperature capability supports deployment in under-hood automotive traction inverters and industrial power converters with high ambient thermal loads. Thermal design must ensure the die temperature remains within this limit under worst-case power dissipation conditions.
Does the TMS320F28379SPTPT support functional safety certification out of the box?
Yes, the TMS320F28379SPTPT is ISO 26262 ASIL B and IEC 61508 SIL 2 certified by TÜV SÜD, with hardware integrity verified to ASIL B/SIL 2 levels. It includes safety mechanisms such as ECC on flash/RAM, windowed watchdog, missing-clock detection, and dual-code security module - enabling use in safety-critical systems without requiring additional external safety monitors.
How many high-resolution PWM channels does the TMS320F28379SPTPT provide?
The TMS320F28379SPTPT provides 16 high-resolution PWM (HRPWM) channels, implemented across eight ePWM modules with both A and B output channels enhanced for sub-nanosecond resolution. These are used for precise timing control of SiC and GaN gate drivers in high-frequency power converters, with programmable dead-band and fault protection integration.
Can the TMS320F28379SPTPT execute code independently on the CLA and main CPU simultaneously?
Yes, the TMS320F28379SPTPT features 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 or ePWM period match). It accesses shared RAM and peripherals without CPU intervention, enabling true parallel execution - for example, CLA handling current-loop updates while C28x manages CAN communication and diagnostics.
What analog-to-digital converter configurations are supported by the TMS320F28379SPTPT?
The TMS320F28379SPTPT integrates four independent 16-/12-bit ADCs. In 16-bit mode, each achieves 1.1MSPS with differential inputs and up to 12 external channels; in 12-bit mode, each reaches 3.5MSPS with single-ended inputs and up to 24 external channels. Each ADC includes a dedicated Sample-and-Hold and hardware post-processing engine with saturation calibration and windowed compare functions.
