Product details
Overview
TMS320F28375SPZPQ from Texas Instruments is a single-core 32-bit floating-point real-time microcontroller optimized for industrial motor control and power conversion. It features a 200MHz C28x CPU with FPU, TMU, VCU-II, and CLA coprocessor; 512KB flash (ECC-protected); 132KB RAM (parity-protected); four 16-/12-bit ADCs (up to 4.4MSPS system throughput); 24 ePWM channels including 16 HRPWM; dual CAN 2.0B interfaces; and USB 2.0 MAC+PHY - deployed in traction inverters and solar string inverters.
For engineers reviewing the TMS320F28375SPZPQ datasheet, TMS320F28375SPZPQ pinout, TMS320F28375SPZPQ application, or TMS320F28375SPZPQ equivalent, key selection considerations include its HTQFP-100 package with 41 GPIOs, ASIL B/SIL 2 functional safety certification, 16-bit ADC resolution at 1.1MSPS per channel, CLA offloading capability, and automotive-grade temperature range (–40°C to 125°C free-air).
Technical Context
The TMS320F28375SPZPQ implements a deterministic real-time control architecture centered on a single C28x CPU core running at 200MHz with IEEE 754 FPU, trigonometric (TMU), and complex math (VCU-II) accelerators. Its CLA coprocessor operates concurrently at 200MHz to handle time-critical control loops independent of the main CPU.
It integrates four independent 16-/12-bit ADCs with differential/single-ended inputs, hardware post-processing (offset calibration, windowed comparators, DAC-referenced thresholds), and SDFM support for isolated current sensing. The analog subsystem interfaces directly with 24 ePWM outputs (16 high-resolution), six eCAP modules, three eQEP units, and eight SDFM input channels.

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F28375S-Q1 | Identical silicon; AEC Q100 qualified for automotive use, with extended qualification testing and traceability documentation | Required for automotive production programs where AEC Q100 compliance is mandatory (e.g., OBC, traction inverter) | Select TMS320F28375S-Q1 when automotive qualification and full PPAP support are required |
| TMS320F28377S | Same package options but with 1MB flash, 164KB RAM, and 169 GPIOs - higher memory and I/O count in ZWT/PTP packages | Preferred for complex systems requiring larger firmware image, more peripheral instances, or expanded sensor/actuator connectivity | Select TMS320F28377S when design requires >512KB flash or >41 GPIOs - not pin-compatible in PZP package |
Compared with TMS320F28375S-Q1, the TMS320F28375SPZPQ offers identical real-time control capability and HTQFP-100 footprint but lacks automotive qualification documentation; versus TMS320F28377S, it trades memory and I/O headroom for cost-optimized footprint in space-constrained industrial power modules.

FAQ
What is the maximum operating temperature specification for the TMS320F28375SPZPQ?
The TMS320F28375SPZPQ is qualified for –40°C to 125°C free-air temperature operation and carries the "Q" suffix denoting AEC Q100 qualification for automotive applications. This rating applies to the full device functionality under specified voltage and load conditions per TI SPRS881K Section 6.4.
Does the TMS320F28375SPZPQ support hardware-based functional safety diagnostics?
Yes, the TMS320F28375SPZPQ includes Hardware Built-in Self Test (HWBIST) for flash, RAM, and peripherals, and is ISO 26262 ASIL B and IEC 61508 SIL 2 certified by TÜV SÜD. These capabilities are integral to the silicon and documented in TI's functional safety package for TMS320F28375SPZPQ.
How many ADC channels are accessible in the TMS320F28375SPZPQ's HTQFP-100 package?
The TMS320F28375SPZPQ in the PZP (HTQFP-100) package supports 14 external ADC input pins - 7 differential channels in 16-bit mode or 14 single-ended channels in 12-bit mode - consistent with the device comparison table in SPRS881K Section 4.
Is the TMS320F28375SPZPQ pin-compatible with other devices in the F2837xS family?
