Product details
Overview
TMS320F28379DPTPT 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 169 GPIOs. It targets high-performance motor control and power conversion systems such as EV traction inverters and solar string inverters.
For engineers reviewing the TMS320F28379DPTPT datasheet, TMS320F28379DPTPT pinout, TMS320F28379DPTPT application, or TMS320F28379DPTPT equivalent, key selection criteria include dual-CPU deterministic latency, CLA offload capability for time-critical loops, integrated analog subsystem with hardware post-processing, and functional safety certification up to ASIL B/SIL 2.
Technical Context
The TMS320F28379DPTPT implements a tightly coupled dual-C28x architecture where each CPU runs at 200MHz with dedicated FPU, TMU, and VCU-II-enabling simultaneous execution of torque/flux loops and system-level diagnostics. Its two CLAs operate independently at 200MHz, respond to peripheral triggers, and execute floating-point code without CPU intervention.
On-chip analog resources include four ADCs supporting both 16-bit (1.1MSPS, differential) and 12-bit (3.5MSPS, single-ended) modes, each with S/H, hardware saturation calibration, windowed comparators with 12-bit DAC references, and trigger-to-sample delay capture-optimized for isolated current sensing and overcurrent protection in three-phase power stages.
