Product details
Overview
TMS320F28377DPTPQ 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 traction inverters and solar string inverters.
For engineers reviewing the TMS320F28377DPTPQ datasheet, TMS320F28377DPTPQ pinout, TMS320F28377DPTPQ application, or TMS320F28377DPTPQ equivalent, key selection criteria include dual-CPU+CLA parallel processing capability, AEC Q100 qualification (Q-grade), 176-pin HLQFP thermal performance, functional safety certification up to ASIL B/SIL 2, and integrated analog subsystem with hardware post-processing.
Technical Context
The TMS320F28377DPTPQ implements a tightly coupled dual-C28x architecture where each CPU runs at 200MHz with dedicated FPU, TMU, and VCU-II for trigonometric and complex math acceleration. Each core pairs with an independent 200MHz CLA that executes time-critical control loops-such as current regulation or protection logic-concurrently with main CPU tasks like communication and diagnostics.
Its analog subsystem includes four ADCs configurable in 16-bit (1.1MSPS, differential) or 12-bit (3.5MSPS, single-ended) mode, each with S/H, hardware offset calibration, windowed comparators, and DAC-referenced thresholds. The integrated SDFM supports isolated shunt current sensing, while CMPSS provides fast overcurrent response via comparator-filtered action.
