Product details
Overview
TMS320F28375DZWTS 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 TMS320F28375DZWTS datasheet, TMS320F28375DZWTS pinout, TMS320F28375DZWTS application, or TMS320F28375DZWTS equivalent, key selection criteria include dual-CPU real-time determinism, on-chip analog subsystem performance (ADC/DAC/CMPSS/SDFM), functional safety certification (ISO 26262 ASIL B, IEC 61508 SIL 2), and nFBGA-337 thermal/power integrity for high-density industrial power conversion designs.
Technical Context
The TMS320F28375DZWTS implements a tightly coupled dual-C28x architecture with interprocessor communication (IPC) and shared memory, enabling deterministic task partitioning - e.g., one core handling torque/current loops while the other manages communications and diagnostics. Each CPU includes dedicated FPU, TMU, and VCU-II for fast trigonometric and complex math operations critical in motor control transforms.
Its analog subsystem features four independent ADCs with hardware post-processing (offset calibration, windowed compare, trigger-to-sample capture), three 12-bit buffered DACs, eight windowed comparators with DAC references, and eight SDFM input channels supporting isolated shunt current sensing - all synchronized to PWM timing for precise closed-loop actuation.

FAQ
What is the operating temperature range for the TMS320F28375DZWTS?
The TMS320F28375DZWTS is rated for –40°C to 125°C junction temperature (S-grade), validated for continuous operation in high-thermal environments such as enclosed traction inverters and outdoor solar power optimizers. This rating aligns with AEC-Q100 stress test conditions for automotive-grade reliability, though the part itself is not Q100-certified.
Does the TMS320F28375DZWTS support functional safety certification?
Yes, the TMS320F28375DZWTS is hardware-integrity certified to ISO 26262 ASIL B and IEC 61508 SIL 2 by TÜV SÜD. Safety documentation - including FMEDA reports, safety manuals, and diagnostic coverage analysis - is available from Texas Instruments to support system-level compliance up to ASIL D and SIL 3.
How many ADC modules does the TMS320F28375DZWTS integrate, and what are their key capabilities?
The TMS320F28375DZWTS integrates four independent 16-/12-bit ADCs. Each supports 1.1MSPS (16-bit) or 3.5MSPS (12-bit) conversion, differential or single-ended inputs, hardware post-processing (offset calibration, windowed compare, trigger-to-sample delay capture), and synchronization to PWM events - enabling precise, low-latency current/voltage sensing in multi-phase power converters.
What package type and ball count does the TMS320F28375DZWTS use?
The TMS320F28375DZWTS uses the ZWT package: a 337-ball New Fine Pitch Ball Grid Array (nFBGA) with 16mm × 16mm body size, lead-free/green construction, and thermal pad design optimized for high-power density PCB layouts in industrial and automotive power electronics.
Can the TMS320F28375DZWTS execute code independently on both CPU cores and CLAs simultaneously?
Yes, the TMS320F28375DZWTS supports true concurrent execution: both C28x CPUs run independent firmware threads, and each CLA executes floating-point control law code triggered by peripheral events (e.g., PWM sync, ADC EOC) - all without CPU intervention. This architecture enables deterministic sub-microsecond loop closure in demanding real-time control applications.
