Texas Instruments TMS320F28375SPZPT

Overview

TMS320F28375SPZPT from Texas Instruments is a single-core C28x 32-bit floating-point real-time microcontroller operating at 200MHz, featuring IEEE 754 FPU, TMU, VCU-II, and CLA coprocessor. It integrates 512KB flash (ECC-protected), 132KB RAM (parity/ECC-protected), four 16-/12-bit ADCs (up to 4.4MSPS system throughput), and 24 ePWM channels with 16 HRPWM outputs. It targets high-precision motor control in EV traction inverters and solar power converters.

For engineers reviewing the TMS320F28375SPZPT datasheet, TMS320F28375SPZPT pinout, TMS320F28375SPZPT application, or TMS320F28375SPZPT equivalent, key selection criteria include its 176-pin HLQFP package, –40°C to 125°C junction temperature rating (S-grade), dual CAN 2.0B interfaces, USB 2.0 MAC+PHY, and functional safety compliance up to IEC 61508 SIL 2 and ISO 26262 ASIL B.

Technical Context

The TMS320F28375SPZPT implements a deterministic real-time control architecture centered on a 200MHz C28x CPU with hardware-accelerated trigonometric (TMU) and complex math (VCU-II) operations. Its independent 200MHz CLA coprocessor handles time-critical control loops-such as current regulation in three-phase inverters-without CPU intervention, enabling parallel execution of diagnostics and communications.

System-level timing integrity is enforced via dual zero-pin 10MHz oscillators, missing-clock detection, and windowed watchdog timer. Analog signal acquisition uses four synchronized 16-bit ADCs with differential inputs, hardware post-processing (offset calibration, windowed comparators), and SDFM support for isolated shunt current sensing-critical for high-efficiency SiC/GaN power stage monitoring.

FAQ

What is the maximum operating junction temperature for the TMS320F28375SPZPT?

The TMS320F28375SPZPT is rated for a junction temperature range of –40°C to 125°C, designated by the 'S' suffix in its part number. This specification is validated per TI's SPRS881K datasheet and supports operation in high-temperature industrial motor drive enclosures and under-hood automotive environments when paired with appropriate thermal design using the PowerPAD package.

Does the TMS320F28375SPZPT support functional safety certification out of the box?

Yes, the TMS320F28375SPZPT is developed to meet functional safety requirements with hardware integrity certified to IEC 61508 SIL 2 and ISO 26262 ASIL B by TÜV SÜD. It includes built-in features such as Hardware Built-in Self Test (HWBIST), ECC on flash and RAM, lockstep-capable peripherals, and safety documentation to accelerate system-level certification for motor drives and energy storage applications.

How many high-resolution PWM channels does the TMS320F28375SPZPT provide?

The TMS320F28375SPZPT provides 16 high-resolution PWM (HRPWM) channels - eight modules each with A and B outputs - delivering sub-nanosecond resolution for precise dead-time control in SiC/GaN-based inverters. This capability is confirmed in the device comparison table (Table 4-1) of SPRS881K and is accessible in the 176-pin PTP package.

Can the TMS320F28375SPZPT execute code independently on both CPU and CLA simultaneously?

Yes, the TMS320F28375SPZPT features a dedicated Control Law Accelerator (CLA) that operates concurrently with the main C28x CPU at 200MHz. The CLA responds to peripheral triggers (e.g., ADC end-of-conversion or PWM timer overflow) and executes floating-point control code without CPU intervention - enabling true parallel processing for time-critical loops in the TMS320F28375SPZPT.

What analog-to-digital converter configurations are supported by the TMS320F28375SPZPT?

The TMS320F28375SPZPT integrates four independent ADCs configurable in 16-bit mode (1.1MSPS each, differential inputs, up to 12 external channels) or 12-bit mode (3.5MSPS each, single-ended inputs, up to 24 external channels). Each ADC includes a dedicated Sample-and-Hold and hardware post-processing (offset calibration, windowed compare) - all confirmed in Section 1 Features and Table 4-1 of SPRS881K.
