Product details
Overview
TMS320F28375SZWTT from Texas Instruments is a single-core 32-bit C28x floating-point MCU with 200MHz CPU, IEEE 754 FPU, TMU, VCU-II, and CLA coprocessor-designed for real-time motor control and power conversion. 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. Used in EV traction inverters, solar string inverters, and industrial servo drives.
For engineers reviewing the TMS320F28375SZWTT datasheet, TMS320F28375SZWTT pinout, TMS320F28375SZWTT application, or TMS320F28375SZWTT equivalent, key selection factors include its 337-ball nFBGA (ZWT) package, –40°C to 105°C temperature grade (T suffix), 512KB flash / 132KB RAM memory configuration, functional safety support up to ASIL B/SIL 2, and pin compatibility within the F2837xS family.
Technical Context
The TMS320F28375SZWTT implements a single C28x CPU + CLA subsystem (200MHz each), distinguishing it from dual-core F2837xD variants. Its analog subsystem includes four independent ADCs with differential/SE input modes, hardware post-processing (windowed comparators, DAC-referenced thresholds), and SDFM channels for isolated current sensing.
Control peripherals feature 24 ePWM outputs with dead-band generation on both standard and high-resolution channels, six eCAP modules, three eQEP interfaces, and configurable logic blocks (CLB) for position manager augmentation. Communications include two ISO 11898-1 CAN modules, three SPI ports, four SCI/UARTs, two I²C, two McBSP, USB 2.0 MAC+PHY, and uPP interface.

FAQ
What is the maximum ADC sampling rate supported by the TMS320F28375SZWTT?
The TMS320F28375SZWTT supports up to 1.1 million samples per second (MSPS) per ADC in 16-bit mode, with four independent ADCs delivering up to 4.4 MSPS system throughput. In 12-bit mode, each ADC achieves 3.5 MSPS for higher-speed acquisition of less critical signals. All ADCs feature hardware post-processing including saturation calibration and windowed compare with interrupt capability - essential for real-time overcurrent protection in power converters.
Does the TMS320F28375SZWTT support functional safety certification?
Yes, the TMS320F28375SZWTT is ISO 26262 ASIL B and IEC 61508 SIL 2 certified by TÜV SÜD. It includes hardware safety mechanisms such as ECC on flash and RAM, windowed watchdog timers, missing-clock detection, and hardware BIST. Safety documentation-including FMEDA reports and safety manuals-is provided by Texas Instruments to support system-level certification of motor drives and energy storage systems.
What package and pin count does the TMS320F28375SZWTT use?
The TMS320F28375SZWTT uses a 337-ball New Fine Pitch Ball Grid Array (nFBGA) package with ZWT suffix, measuring 16mm × 16mm with 0.8mm ball pitch. This package provides 169 GPIOs plus dedicated power, ground, clock, and debug pins - optimized for high-density industrial PCB layouts requiring thermal performance and signal integrity in noisy power electronics environments.
How does the CLA coprocessor in the TMS320F28375SZWTT improve real-time performance?
The CLA in the TMS320F28375SZWTT is an independent 32-bit floating-point processor running at 200MHz, triggered by peripheral events (e.g., ADC end-of-conversion or PWM timer overflow). It executes time-critical control code-such as current loop regulation-concurrently with the main C28x CPU, effectively doubling real-time throughput. This allows the main CPU to handle communications, diagnostics, and user interfaces without compromising control loop determinism.
Is the TMS320F28375SZWTT pin-compatible with other F2837xS devices?
Yes, the TMS320F28375SZWTT is pin-compatible with all F2837xS-family devices in the same ZWT (337-ball nFBGA) package, including TMS320F28377S and TMS320F28379S. Peripheral availability matches the ZWT variant across the family - meaning PCBs designed for one ZWT-part can be reused with others, subject to firmware adaptation for differing memory sizes and peripheral enablement (e.g., CLA and ADC count are identical across ZWT-packaged F2837xS parts).
