Texas Instruments TMS320F28375SPTPT

Overview

TMS320F28375SPTPT from Texas Instruments is a 32-bit floating-point real-time microcontroller with a 200MHz C28x CPU, IEEE 754 FPU, Trigonometric Math Unit (TMU), and Viterbi/Complex Math Unit (VCU-II), designed for high-precision motor control and digital power conversion. It integrates dual-zone security, 512KB ECC-protected flash, 132KB RAM, four 16-/12-bit ADCs (up to 4.4MSPS system throughput), and 24 ePWM channels with 16 high-resolution outputs - enabling closed-loop control in EV traction inverters and solar string inverters.

For engineers reviewing the TMS320F28375SPTPT datasheet, TMS320F28375SPTPT pinout, TMS320F28375SPTPT application, or TMS320F28375SPTPT equivalent, key selection criteria include its -40°C to 125°C junction temperature rating, 176-pin HLQFP (PTP) package, CLA coprocessor independence, ISO 26262 ASIL B functional safety certification, and support for CAN, USB 2.0, and sigma-delta current sensing via SDFM.

Technical Context

The TMS320F28375SPTPT implements a single-CPU subsystem (C28x + CLA) architecture - distinct from dual-core F2837xD variants - with the CLA executing time-critical control loops at 200MHz independently of the main CPU. Its analog subsystem includes four ADCs configurable in 16-bit (1.1MSPS, differential) or 12-bit (3.5MSPS, single-ended) mode, each with hardware post-processing (windowed comparators, DAC-referenced thresholds, error-from-setpoint calculation).

Control peripherals are optimized for power electronics: 24 ePWM channels with dead-band generation on both standard and high-resolution outputs, six eCAP modules for precise timing capture, three eQEP interfaces for motor position feedback, and eight SDFM input channels supporting isolated shunt-based current measurement. The device supports two CAN 2.0B modules, four SCI/UARTs, three SPIs, two I²C, two McBSPs, and a USB 2.0 MAC+PHY interface.
