Product details
Overview
TMS320F28379DZWTS 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 in EV charging stations and solar inverters.
For engineers reviewing the TMS320F28379DZWTS datasheet, TMS320F28379DZWTS pinout, TMS320F28379DZWTS application, or TMS320F28379DZWTS equivalent, key selection criteria include dual-CPU deterministic latency, CLA offload capability for time-critical loops, 16-bit ADC resolution with hardware post-processing, functional safety certification up to ASIL B/SIL 2, and nFBGA-337 thermal performance at 125°C junction.
Technical Context
The TMS320F28379DZWTS 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/position control and diagnostics. Its two CLAs operate independently at 200MHz, responding to peripheral triggers without CPU intervention.
On-chip analog subsystem includes four ADCs supporting 16-bit mode (1.1MSPS each, differential inputs) and 12-bit mode (3.5MSPS each, single-ended), each with integrated S/H and hardware-accelerated post-processing (offset calibration, windowed compare, DAC-referenced comparators). The Sigma-Delta Filter Module (SDFM) provides eight input channels with parallel filtering for isolated current sensing.
