Product details
Overview
TMS320F28379DZWTT from Texas Instruments is a dual-core 32-bit real-time microcontroller featuring two 200MHz C28x CPUs, IEEE 754 single-precision FPU, TMU, VCU-II, and two independent 200MHz CLA coprocessors. It integrates 1MB flash (ECC-protected), 204KB RAM (ECC/parity-protected), four 16-/12-bit ADCs (up to 4.4MSPS system throughput), 24 ePWM channels with 16 HRPWM, and dual CAN, USB 2.0, and uPP interfaces - deployed in traction inverter motor control and solar power optimizers.
For engineers reviewing the TMS320F28379DZWTT datasheet, TMS320F28379DZWTT pinout, TMS320F28379DZWTT application, or TMS320F28379DZWTT equivalent, key selection criteria include dual-CPU+CLA real-time partitioning capability, 169 GPIO with input filtering, functional safety certification up to ASIL B/SIL 2, and nFBGA-337 package thermal performance for high-power industrial inverters.
Technical Context
The TMS320F28379DZWTT implements a tightly coupled dual-C28x architecture where each CPU runs at 200MHz with dedicated FPU, TMU, and VCU-II accelerators for fast trigonometric and complex math operations. Its two CLAs execute floating-point code independently, triggered by peripheral events, enabling concurrent torque-loop computation and communication/diagnostic tasks.
System-level integration includes dual EMIFs supporting ASRAM/SDRAM, eight SDFM channels for isolated shunt current sensing, six eCAP modules, three eQEP modules, and a Configurable Logic Block (CLB) augmenting peripheral logic for position manager solutions - all coordinated via interprocessor communication (IPC) and dual-zone security with unique ID and DCSM protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
