Texas Instruments TMS320F28379SZWTS

Overview

TMS320F28379SZWTS from Texas Instruments is a 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 HRPWM outputs, dual CAN, USB 2.0, and CLB for industrial motor control and solar inverter applications.

For engineers reviewing the TMS320F28379SZWTS datasheet, TMS320F28379SZWTS pinout, TMS320F28379SZWTS application, or TMS320F28379SZWTS equivalent, key selection criteria include dual-core real-time compute capability (C28x + CLA), functional safety certification (ISO 26262 ASIL B, IEC 61508 SIL 2), 337-ball nFBGA package (ZWT), –40°C to 125°C junction temperature rating (S-grade), and integrated analog/control peripherals for closed-loop power conversion systems.

Technical Context

The TMS320F28379SZWTS implements a dual-subsystem architecture where the main C28x CPU and independent CLA coprocessor each run at 200MHz, enabling concurrent execution of control loops and background tasks. Its analog subsystem includes four independent ADCs supporting both 16-bit (1.1MSPS) and 12-bit (3.5MSPS) modes with differential/single-ended inputs, hardware post-processing (offset calibration, windowed comparators, DAC-referenced thresholds), and SDFM integration for isolated current sensing.

System-level timing and reliability are enforced via two internal zero-pin 10MHz oscillators, on-chip crystal oscillator, windowed watchdog timer, missing-clock detection, and dual-zone security with unique ID. The device supports pin-bootable interfaces including CAN, SPI, SCI, I²C, uPP, and USB 2.0 with integrated PHY - all operating under 1.2V core and 3.3V I/O voltage domains.

FAQ

What is the maximum ADC sampling rate supported by the TMS320F28379SZWTS?

The TMS320F28379SZWTS supports up to 1.1 million samples per second (MSPS) per ADC in 16-bit mode, yielding up to 4.4MSPS system throughput across its four independent ADCs. In 12-bit mode, each ADC achieves 3.5MSPS for up to 14MSPS total throughput. These rates are achievable with hardware-triggered conversions and on-chip post-processing enabled.

Does the TMS320F28379SZWTS support functional safety certification for automotive use?

The TMS320F28379SZWTS is certified to ISO 26262 ASIL B and IEC 61508 SIL 2 by TÜV SÜD, with documentation supporting system-level design up to ASIL D and SIL 3. However, it is not AEC-Q100 qualified - for automotive applications requiring Q100, the pin-compatible TMS320F28377S-Q1 or TMS320F28375S-Q1 should be selected instead.

How many high-resolution PWM channels does the TMS320F28379SZWTS provide?

The TMS320F28379SZWTS provides 16 high-resolution PWM (HRPWM) channels, distributed across eight ePWM modules (A and B legs of each). Each HRPWM output achieves <150ps resolution, enabling precise dead-time control and gate-drive timing critical for SiC and GaN power stages in high-efficiency inverters.

What package type and dimensions does the TMS320F28379SZWTS use?

The TMS320F28379SZWTS uses the 337-ball New Fine Pitch Ball Grid Array (nFBGA) package with ZWT suffix, measuring 16mm × 16mm in body size. It is lead-free, RoHS-compliant, and features thermal vias compatible with standard PCB reflow profiles for industrial and automotive thermal environments.

Can the TMS320F28379SZWTS execute control code independently on both CPU and CLA simultaneously?

Yes - the TMS320F28379SZWTS features a fully independent Control Law Accelerator (CLA) that runs at 200MHz and executes floating-point code triggered by peripheral events (e.g., ADC end-of-conversion, PWM timer overflow). This allows the CLA to handle time-critical control loops while the main C28x CPU manages communications, diagnostics, and supervisory functions concurrently.
