Product details
Overview
TMS320F28376DPTPT from Texas Instruments is a dual-core 32-bit C28x real-time microcontroller with two 200MHz CPUs, IEEE 754 single-precision 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 TMS320F28376DPTPT datasheet, TMS320F28376DPTPT pinout, TMS320F28376DPTPT application, or TMS320F28376DPTPT equivalent, key selection criteria include dual-CPU real-time determinism, on-chip analog subsystem precision (16-bit ADC + DAC + SDFM), functional safety certification (ASIL B/SIL 2), and HLQFP-176 thermal performance for industrial power electronics.
Technical Context
The TMS320F28376DPTPT implements a tightly coupled dual-C28x architecture with interprocessor communication (IPC) and shared memory, enabling deterministic task partitioning-e.g., one core handling torque/current loops while the other manages communications and diagnostics. Each CPU includes dedicated FPU, TMU, and VCU-II for fast trigonometric and complex math operations critical in field-oriented control.
Its analog subsystem features four independent ADCs with differential 16-bit mode (1.1MSPS each), hardware post-processing (offset calibration, windowed compare, error-from-setpoint), three 12-bit buffered DACs, and eight SDFM input channels supporting isolated shunt current sensing-enabling full analog signal chain integration without external signal conditioning.

How many high-resolution PWM channels does the TMS320F28376DPTPT provide?
The TMS320F28376DPTPT provides 16 high-resolution PWM (HRPWM) channels, distributed across eight ePWM modules with both A and B channel enhancement. These deliver sub-nanosecond resolution and independent dead-band control-critical for minimizing switching losses in SiC/GaN-based inverters.
What package type and thermal characteristics does the TMS320F28376DPTPT use?
The TMS320F28376DPTPT uses a 176-pin PowerPAD™ Thermally Enhanced Low-Profile Quad Flatpack (HLQFP, PTP suffix), with a 26mm × 26mm body and exposed thermal pad.
