Texas Instruments TMS320F28379SPZPS

Overview

TMS320F28379SPZPS 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 four 16-/12-bit ADCs (up to 4.4MSPS system throughput), 24 ePWM channels with 16 HRPWM outputs, dual CAN modules, USB 2.0 (MAC+PHY), and 169 GPIOs - deployed in industrial motor drives, solar inverters, and EV charging power modules.

For engineers reviewing the TMS320F28379SPZPS datasheet, TMS320F28379SPZPS pinout, TMS320F28379SPZPS application, or TMS320F28379SPZPS equivalent, key selection criteria include CLA coprocessing capability, ASIL B/SIL 2 functional safety certification, 1MB ECC-protected flash, 164KB RAM, and support for isolated current sensing via SDFM + CMPSS in high-reliability closed-loop control systems.

Technical Context

The TMS320F28379SPZPS implements a single-core C28x CPU + CLA dual-execution architecture where the CLA independently handles time-critical control loops (e.g., PWM update, ADC post-processing) while the main CPU manages communications, diagnostics, and higher-layer logic. Its analog subsystem includes four independent ADCs with differential/SE input modes, hardware-accelerated offset calibration, windowed comparators with DAC references, and integrated SDFM for sigma-delta modulator interfacing.

System-level timing relies on dual zero-pin 10MHz oscillators, on-chip crystal oscillator, and PLL-based clock generation supporting multiple low-power modes with external wakeup. Peripheral interconnect uses a data bus bridge architecture enabling concurrent access to EMIF1/EMIF2, CAN, USB, uPP, and serial interfaces without CPU arbitration bottlenecks.

FAQ

What is the maximum operating junction temperature for the TMS320F28379SPZPS?

The TMS320F28379SPZPS is rated for –40°C to 125°C junction temperature (S-grade), validated per JEDEC JESD22-A108. This allows deployment in high-ambient environments such as under-hood automotive charging modules or enclosed industrial inverters without forced cooling. The HTQFP package's exposed thermal pad must be soldered to a PCB copper pour for effective heat transfer.

Does the TMS320F28379SPZPS support functional safety certification out of the box?

Yes, the TMS320F28379SPZPS is ISO 26262 ASIL B and IEC 61508 SIL 2 certified by TÜV SÜD, with hardware integrity verified and safety documentation (FMEDA, safety manual, diagnostic coverage reports) available from TI. No additional qualification is required to use it in safety-related subsystems meeting these ASIL/SIL targets.

How many independent ADC modules does the TMS320F28379SPZPS integrate?

The TMS320F28379SPZPS integrates four independent 16-/12-bit ADC modules (ADC A, B, C, D), each capable of simultaneous sampling and hardware-accelerated post-processing (offset calibration, window compare, trigger-to-sample capture). This enables full 3-phase current + DC-link voltage acquisition in a single conversion window.

Can the TMS320F28379SPZPS execute control algorithms concurrently on CPU and CLA?

Yes - the TMS320F28379SPZPS features a true parallel architecture: the 200MHz C28x CPU and 200MHz CLA operate independently, sharing memory via 128-word message RAM. CLA code is triggered by peripheral events (e.g., ADC end-of-conversion), enabling deterministic sub-microsecond response for critical loops without CPU scheduling overhead.

What communication interfaces are available on the TMS320F28379SPZPS?

The TMS320F28379SPZPS provides two CAN 2.0B modules, four SCI/UART ports, three SPI ports, two I²C interfaces, two McBSPs, one USB 2.0 (MAC+PHY), and one uPP interface. All are accessible on the 100-pin HTQFP package, with pin multiplexing allowing flexible assignment based on system requirements.
