Product details
Overview
TMS320F28376DZWTS 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 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 in EV traction inverters and solar power converters.
For engineers reviewing the TMS320F28376DZWTS datasheet, TMS320F28376DZWTS pinout, TMS320F28376DZWTS application, or TMS320F28376DZWTS equivalent, key selection criteria include dual-CPU real-time partitioning, 169-pin nFBGA package thermal performance, 512KB flash/ECC memory configuration, and functional safety support up to ASIL B/SIL 2 for industrial and automotive power systems.
Technical Context
The TMS320F28376DZWTS implements a tightly coupled dual-C28x architecture where each CPU runs at 200MHz with dedicated FPU, TMU, and VCU-II accelerators for trigonometric and complex math. Its two independent CLAs execute floating-point code concurrently with main CPUs, enabling parallel torque/speed loop execution.
It features four independent 16-/12-bit ADCs with differential/single-ended inputs, hardware post-processing (offset calibration, windowed comparators, DAC-referenced thresholds), and SDFM modules for isolated current sensing. The analog subsystem supports up to 24 external ADC channels in 12-bit mode and 12 in 16-bit mode.
