Product details
Overview
TMS320F28376DPTPS 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 - deployed in traction inverter motor control and solar power optimizers.
For engineers reviewing the TMS320F28376DPTPS datasheet, TMS320F28376DPTPS pinout, TMS320F28376DPTPS application, or TMS320F28376DPTPS equivalent, key selection criteria include dual-CPU real-time partitioning, 169-pin HLQFP thermal performance, functional safety certification up to ASIL B/SIL 2, and support for high-resolution current sensing via SDFM + CMPSS.
Technical Context
The TMS320F28376DPTPS implements a tightly coupled dual-C28x architecture where each CPU runs at 200MHz with dedicated FPU, TMU, and VCU-II - enabling concurrent execution of torque-loop math and position estimation. Its two CLAs operate independently at 200MHz, servicing time-critical PWM updates and ADC post-processing without CPU intervention.
Peripherals are partitioned across two CPU domains with shared memory (128KB GS RAM) and interprocessor communication (IPC) module. The analog subsystem includes four ADCs with differential/single-ended modes, hardware-accelerated post-processing (windowed comparators, DAC-referenced thresholds), and eight SDFM input channels supporting isolated shunt current measurement.
