Product details
Overview
TMS320F28375SPTPS from Texas Instruments is a 32-bit floating-point real-time microcontroller with a 200MHz C28x CPU, IEEE 754 FPU, TMU, VCU-II, and single CLA coprocessor. 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. It targets high-precision motor control in EV traction inverters and solar power converters.
For engineers reviewing the TMS320F28375SPTPS datasheet, TMS320F28375SPTPS pinout, TMS320F28375SPTPS application, or TMS320F28375SPTPS equivalent, key selection factors include its –40°C to 125°C junction temperature rating, 512KB flash / 132KB RAM memory configuration, nFBGA/HLQFP/HTQFP package options, and functional safety compliance up to ASIL B/SIL 2.
Technical Context
The TMS320F28375SPTPS implements a single-CPU subsystem (C28x + CLA) derived from the dual-core F2837xD family, enabling deterministic real-time control without inter-core synchronization overhead. Its analog subsystem features hardware-accelerated ADC post-processing-including windowed comparators with 12-bit DAC references and SDFM support for isolated shunt current sensing.
Control execution is partitioned across the main C28x CPU and independent 200MHz CLA, allowing concurrent handling of time-critical PWM updates and background tasks like communication or diagnostics. The device supports pin-bootable peripherals including CAN, SPI, SCI, I²C, and uPP, with EMIF1 for external memory expansion.

FAQ
What is the maximum operating junction temperature of the TMS320F28375SPTPS?
The TMS320F28375SPTPS is rated for a maximum junction temperature of 125°C, as indicated by the 'S' temperature grade suffix. This specification allows reliable operation in demanding industrial and automotive under-hood environments where ambient temperatures exceed 85°C. Thermal design must ensure that power dissipation and PCB layout maintain junction temperature within this limit during full-load operation.
Does the TMS320F28375SPTPS support functional safety certification?
Yes, the TMS320F28375SPTPS is developed for functional safety applications and certified by TÜV SÜD to ISO 26262 up to ASIL B and IEC 61508 up to SIL 2. Hardware integrity meets ASIL B/SIL 2 requirements, and TI provides safety documentation including FMEDA reports and diagnostic coverage analysis to support system-level certification efforts.
How many ADC modules does the TMS320F28375SPTPS integrate, and what are their resolution modes?
The TMS320F28375SPTPS integrates four independent ADC modules. Each supports both 16-bit mode (1.1MSPS, differential inputs, up to 12 external channels) and 12-bit mode (3.5MSPS, single-ended inputs, up to 24 external channels). All ADCs feature hardware post-processing including offset calibration, error-from-setpoint calculation, and eight windowed comparators with 12-bit DAC references.
What package options are available for the TMS320F28375SPTPS, and which one corresponds to the 'PTPS' suffix?
The TMS320F28375SPTPS is offered in three package variants: 337-ball nFBGA (ZWT), 176-pin HLQFP (PTP), and 100-pin HTQFP (PZP). The 'PTPS' suffix explicitly denotes the 176-pin PowerPAD™ Thermally Enhanced Low-Profile Quad Flatpack (HLQFP) package, which provides superior thermal performance for high-power-density motor control designs.
Can the TMS320F28375SPTPS execute control algorithms concurrently on both CPU and CLA?
Yes, the TMS320F28375SPTPS features a dedicated 200MHz Control Law Accelerator (CLA) that operates independently of the main C28x CPU. The CLA responds to peripheral triggers (e.g., ADC end-of-conversion, PWM timer overflow) and executes floating-point control code in parallel, enabling true hardware-level concurrency for time-critical loops such as current regulation while the CPU handles communications and diagnostics.
