Product details
Overview
TMS320F28375DPTPT 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 176-pin HLQFP package - deployed in EV traction inverters and solar power optimizers.
For engineers reviewing the TMS320F28375DPTPT datasheet, TMS320F28375DPTPT pinout, TMS320F28375DPTPT application, or TMS320F28375DPTPT equivalent, key selection criteria include dual-CPU deterministic latency, CLA offload capability for torque-loop execution, 169 GPIO with input filtering, functional safety certification up to ASIL B/SIL 2, and 1MB flash with ECC protection.
Technical Context
The TMS320F28375DPTPT implements a tightly coupled dual-C28x architecture where each CPU runs at 200MHz with dedicated FPU, TMU, and VCU-II - enabling simultaneous high-precision motor control and signal processing. Its two CLAs execute floating-point code independently, triggered by peripheral events such as PWM sync or ADC EOC, freeing main CPUs for communication and diagnostics.
On-chip analog subsystem includes four ADCs supporting both 16-bit (1.1MSPS, differential) and 12-bit (3.5MSPS, single-ended) modes, each with hardware post-processing (offset calibration, windowed compare, DAC-referenced comparators). The SDFM module provides 8 input channels with parallel sigma-delta filtering for isolated current sensing in high-voltage power stages.
