Product details
Overview
TMS320F28374SZWTTR from Texas Instruments is a 32-bit floating-point real-time microcontroller with dual 200MHz C28x CPU and CLA coprocessor, IEEE 754 FPU, TMU, VCU-II, 512KB flash, 132KB RAM, four 16-/12-bit ADCs (up to 4.4MSPS), 24 ePWM channels (16 HRPWM), two CAN modules, USB 2.0, and SDFM-designed for high-precision motor control in EV traction inverters and solar power converters.
For engineers reviewing the TMS320F28374SZWTTR datasheet, TMS320F28374SZWTTR pinout, TMS320F28374SZWTTR application, or TMS320F28374SZWTTR equivalent, key selection criteria include functional safety compliance (ISO 26262 ASIL B, IEC 61508 SIL 2), nFBGA-337 package thermal performance, CLA offloading capability, and ADC post-processing features for closed-loop current sensing.
Technical Context
The TMS320F28374SZWTTR implements a single-CPU subsystem (C28x + CLA) architecture derived from the F2837xS family, operating at 200MHz with hardware-accelerated trigonometric (TMU) and complex math (VCU-II) functions. Its CLA executes time-critical control loops independently of the main CPU, enabling deterministic response in fast-switching power electronics.
It integrates four independent 16-/12-bit ADCs with hardware post-processing (offset calibration, windowed comparators, DAC-referenced thresholds), eight SDFM input channels for isolated shunt current measurement, and dual CAN 2.0B interfaces with pin-bootable configuration-supporting fault-tolerant communication in automotive and industrial drive systems.
