Texas Instruments TMS320F28379SPZPT

Overview

TMS320F28379SPZPT 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 HRPWM, dual CAN, USB 2.0, and CLB for industrial motor control and solar inverter applications.

For engineers reviewing the TMS320F28379SPZPT datasheet, TMS320F28379SPZPT pinout, TMS320F28379SPZPT application, or TMS320F28379SPZPT equivalent, key selection criteria include dual-core real-time compute capability (C28x + CLA), functional safety certification (ISO 26262 ASIL B / IEC 61508 SIL 2), 100-pin HTQFP package with 41 GPIOs, and support for isolated current sensing via SDFM and comparator subsystem.

Technical Context

The TMS320F28379SPZPT implements a single-CPU subsystem architecture (vs. dual-CPU F2837xD), with one 200MHz C28x core and one independent 200MHz CLA coprocessor executing time-critical control loops concurrently. Its analog subsystem includes four independent ADCs supporting both 16-bit (1.1MSPS) and 12-bit (3.5MSPS) modes, each with dedicated S/H, hardware post-processing (offset calibration, windowed compare), and integrated 12-bit DAC references.

Control peripherals are optimized for power electronics: 24 ePWM channels (16 with high-resolution A/B edges), six eCAP modules, three eQEP interfaces, eight SDFM input channels (2 parallel filters per channel), and a Configurable Logic Block (CLB) with four tiles for custom logic augmentation of PWM, capture, or protection functions - all operating under functional safety constraints up to ASIL B.

FAQ

What is the maximum operating junction temperature for the TMS320F28379SPZPT?

The TMS320F28379SPZPT is rated for a junction temperature range of –40°C to 125°C (S-grade), validated for continuous operation in demanding industrial and automotive power conversion environments. This rating aligns with its functional safety certification to ISO 26262 ASIL B and IEC 61508 SIL 2, ensuring reliability under thermal stress in solar inverters and traction drives where ambient temperatures exceed 85°C.

Does the TMS320F28379SPZPT support USB 2.0 device functionality?

Yes, the TMS320F28379SPZPT integrates a full-speed USB 2.0 port with on-chip MAC and PHY, enabling direct connection to host systems without external transceivers. This allows firmware updates, debug communication, and data logging in applications such as solar inverters and industrial UPS units where field serviceability and remote monitoring are required.

How many independent analog-to-digital converters does the TMS320F28379SPZPT include?

The TMS320F28379SPZPT includes four independent 16-/12-bit analog-to-digital converters (ADCs), each with dedicated sample-and-hold circuitry and hardware post-processing. This enables simultaneous high-precision acquisition of voltage, current, temperature, and auxiliary signals - critical for multi-sensor motor control and grid-synchronized power conversion where phase alignment and throughput are essential.

Is the TMS320F28379SPZPT pin-compatible with other devices in the F2837xS family?

Yes, the TMS320F28379SPZPT is pin-compatible with other 100-pin HTQFP variants in the F2837xS family (e.g., TMS320F28377SPZPT and TMS320F28375SPZPT) within the same package type (PZP suffix), allowing hardware reuse across performance tiers. However, peripheral enablement (e.g., number of ADCs, ePWM channels, CLB) differs per variant and must be verified in software initialization.

What safety certifications apply to the TMS320F28379SPZPT?

The TMS320F28379SPZPT is certified to ISO 26262 up to ASIL B and IEC 61508 up to SIL 2 by TÜV SÜD, with hardware integrity validated for safety mechanisms including ECC memory, watchdog timers, and clock failure detection. Documentation supporting system-level safety design (e.g., FMEDA reports, safety manuals) is available from Texas Instruments for use in automotive and industrial safety-critical applications.
