Product details
Overview
TMS320F28375SPZPQR 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 512KB flash (ECC-protected), 132KB RAM (parity-protected), four 16-/12-bit ADCs (up to 4.4MSPS system throughput), 24 ePWM channels (16 HRPWM), dual CAN, USB 2.0, and SDFM - deployed in EV charging station power modules and solar string inverters.
For engineers reviewing the TMS320F28375SPZPQR datasheet, TMS320F28375SPZPQR pinout, TMS320F28375SPZPQR application, or TMS320F28375SPZPQR equivalent, key selection criteria include its HTQFP-100 package with 41 GPIOs, -40°C to 125°C junction temperature rating, functional safety compliance up to ASIL B/SIL 2, and support for closed-loop control with hardware-accelerated trigonometric and complex math.
Technical Context
The TMS320F28375SPZPQR implements a single C28x CPU + CLA subsystem (200MHz each), with TMU and VCU-II offloading trigonometric and Viterbi/complex operations from the main core. Its analog subsystem includes four independent ADCs supporting simultaneous 16-bit (1.1MSPS) and 12-bit (3.5MSPS) modes, each with S/H, hardware post-processing, and windowed comparators tied to 12-bit DAC references.
Control peripherals include 24 ePWM channels (16 with high-resolution A/B pairs), six eCAP modules, three eQEP modules, and eight SDFM input channels (2 parallel filters per channel) for isolated shunt current sensing. Communications are served by two CAN 2.0B modules, four SCI/UARTs, three SPIs, two I2Cs, one USB 2.0 (MAC+PHY), and one uPP interface - all pin-bootable and multiplexed on 41 GPIOs in the PZP package.

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 | AEC Q100 Grade 0 qualified (–40°C to +150°C), same HTQFP-100 package and feature set - adds automotive-specific test coverage and failure-in-time (FIT) data. | Required for automotive traction inverters and onboard chargers where AEC Q100 compliance is mandatory. | Select TMS320F28375S-Q1 when automotive qualification and extended temperature operation are required; otherwise, TMS320F28375SPZPQR offers identical functionality at lower cost. |
| TMS320F28377S | Same package options but larger memory: 1MB flash, 164KB RAM, 169 GPIOs (in ZWT/PTP), and full peripheral complement - no reduction in ADC count or PWM channels. | Suitable for more complex systems requiring larger firmware, additional data logging buffers, or expanded I/O for multi-axis control or redundancy. | Choose TMS320F28377S when scaling beyond 512KB flash or needing >41 GPIOs; TMS320F28375SPZPQR remains optimal for cost-sensitive, space-constrained 100-pin designs. |
Compared with TMS320F28375S-Q1, the TMS320F28375SPZPQR lacks AEC Q100 qualification but matches its real-time control performance and peripheral integration; compared with TMS320F28377S, it retains identical ADC, PWM, and safety features while reducing flash/RAM and GPIO count - making it ideal for streamlined, production-optimized power conversion designs.

FAQ
What is the maximum operating junction temperature for the TMS320F28375SPZPQR?
The TMS320F28375SPZPQR is rated for a junction temperature range of –40°C to +125°C, consistent with its 'S' temperature grade designation. This specification is validated per TI's recommended operating conditions and thermal resistance characteristics in the SPRS881K datasheet. The device includes on-chip temperature sensor and thermal shutdown circuitry to protect against sustained overtemperature operation. Thermal design must account for the HTQFP-100 package's θJA of 35.2°C/W (with 2-layer board, 2-oz copper).
Does the TMS320F28375SPZPQR support hardware-accelerated trigonometric math?
Yes, the TMS320F28375SPZPQR integrates a Trigonometric Math Unit (TMU) that accelerates sine, cosine, arctangent, and magnitude calculations in hardware - reducing execution time for Park/Clarke transforms and field-oriented control loops by up to 5× versus software-only implementation. This accelerator operates alongside the C28x CPU and CLA, and is accessible via intrinsic functions in C2000Ware and TI C28x compiler toolchain.
How many ADC modules does the TMS320F28375SPZPQR include, and what are their key capabilities?
The TMS320F28375SPZPQR includes four independent 16-/12-bit analog-to-digital converters. Each supports 16-bit mode at 1.1MSPS (differential, 12 external channels) or 12-bit mode at 3.5MSPS (single-ended, 24 external channels). All ADCs feature integrated Sample-and-Hold, hardware post-processing (offset calibration, error-from-setpoint, windowed compare), and trigger-to-sample delay capture - enabling synchronized, high-precision acquisition across multiple current/voltage sensors.
Is the TMS320F28375SPZPQR pin-compatible with other devices in the F2837xS family?
Yes, the TMS320F28375SPZPQR is pin-compatible with other F2837xS devices offered in the same HTQFP-100 (PZP) package, including TMS320F28377S-PZP and TMS320F28375S-Q1-PZP. Pin assignments for power, ground, GPIO, ADC, PWM, and communication interfaces are identical across these variants. However, peripheral enablement (e.g., EMIF2, second CAN, full GPIO count) may differ - verified in the Device Comparison table (Table 4-1) of SPRS881K.
What functional safety certifications apply to the TMS320F28375SPZPQR?
The TMS320F28375SPZPQR is certified to ISO 26262 ASIL B (hardware level) and IEC 61508 SIL 2 by TÜV SÜD, with documentation available to support system-level development up to ASIL D and SIL 3. It includes hardware safety mechanisms such as ECC on flash, parity on RAM, windowed watchdog timer, missing-clock detection, and hardware BIST - all detailed in the Functional Safety section (Section 7.15) of the SPRS881K datasheet.
