Product details
Overview
TMS320F28379DPTPQ from Texas Instruments is a dual-core 32-bit real-time microcontroller with two 200MHz C28x CPUs, IEEE 754 FPU, TMU, VCU-II, and two independent 200MHz CLA coprocessors. It integrates four 16-/12-bit ADCs (up to 4.4MSPS system throughput), 24 ePWM channels (16 HRPWM), dual CAN, USB 2.0, and 176-pin HLQFP package - deployed in EV traction inverters and solar power optimizers.
For engineers reviewing the TMS320F28379DPTPQ datasheet, TMS320F28379DPTPQ pinout, TMS320F28379DPTPQ application, or TMS320F28379DPTPQ equivalent, key selection criteria include dual-CPU real-time determinism, ASIL B/SIL 2 functional safety certification, 1MB ECC-protected flash, 204KB RAM with dual-zone security, and support for isolated current sensing via SDFM + CMPSS.
Technical Context
The TMS320F28379DPTPQ implements a tightly coupled dual-C28x architecture where each CPU runs at 200MHz with dedicated FPU, TMU, and VCU-II for motor control math acceleration. Each core has private L1 RAM (36KB), shared global RAM (128KB), and message RAM (2KB) for interprocessor communication.
Its control subsystem includes 24 ePWM channels with dead-band generation on both standard and high-resolution outputs, six eCAP modules, three eQEP interfaces, eight SDFM input channels with parallel filtering, and a Configurable Logic Block (CLB) for hardware-augmented peripheral logic - all synchronized across CPU/CLA domains for deterministic closed-loop execution.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-core real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F28379D-ZWT | Same dual-core architecture and peripherals, but in 337-ball nFBGA (16mm × 16mm) instead of 176-pin HLQFP | Better thermal performance and higher pin count (169 GPIO vs. 97 in PTP), suited for space-constrained, high-channel-count systems | Select ZWT for PCB area optimization and maximum peripheral access; choose PTP for thermal management simplicity and legacy QFP compatibility |
| TMS320F28377D-PTP | Single 512KB flash bank (vs. 1MB), reduced RAM (172KB), no CLB, and only 15 ePWM channels - otherwise identical CPU/CLA/ADC specs | Targeted at cost-sensitive industrial drives where full memory/peripheral headroom is unnecessary | Choose F28377D-PTP when application firmware fits within 512KB flash and CLB logic is not required; retain F28379DPTPQ for future-proofing and safety-critical redundancy |
Compared with TMS320F28379D-ZWT, the PTP package offers easier thermal design and reworkability; compared with TMS320F28377D-PTP, the F28379DPTPQ delivers double flash capacity, CLB support, and full 24-channel ePWM - critical for next-generation OBC and bidirectional converter architectures requiring hardware-level fault containment.
