Texas Instruments TMS320F28075PTPQ

Overview

TMS320F28075PTPQ from Texas Instruments is a C2000™ real-time microcontroller featuring a 120MHz C28x CPU with IEEE 754 single-precision FPU and Trigonometric Math Unit (TMU), 512KB ECC-protected flash, 100KB RAM (ECC/parity-protected), and triple 12-bit ADCs delivering 3.1MSPS each. It integrates 24 ePWM channels (16 HRPWM-capable), dual CAN 2.0B modules, USB 2.0 MAC+PHY, and CLA coprocessor for parallel real-time control in high-accuracy motor drives and power converters.

For engineers reviewing the TMS320F28075PTPQ datasheet, TMS320F28075PTPQ pinout, TMS320F28075PTPQ application, or TMS320F28075PTPQ equivalent, key selection criteria include its AEC Q100-qualified –40°C to 125°C free-air temperature rating, 176-pin HLQFP PowerPAD™ package with thermal pad, functional safety compliance up to ASIL B/SIL 2, and support for simultaneous three-phase analog acquisition with hardware post-processing.

Technical Context

The TMS320F28075PTPQ implements a dual-processor architecture: the main C28x CPU executes deterministic real-time control loops while the independent 120MHz CLA handles time-critical tasks like PWM fault response and ADC post-processing-enabling concurrent execution without CPU intervention. Its analog subsystem includes three synchronized 12-bit ADCs with per-channel S/H, eight windowed comparators with DAC references, and three buffered 12-bit DAC outputs for closed-loop feedback generation.

System-level timing relies on dual zero-pin 10MHz internal oscillators, on-chip crystal oscillator support, and missing-clock detection. Peripheral connectivity includes two CAN interfaces compliant with ISO 11898-1, four SCI/UART ports, three SPIs, two I²C buses, two McBSPs, and an EMIF supporting ASRAM/SDRAM-configured via multiplexed GPIO with input filtering and programmable pullup/pulldown.

FAQ

What is the operating temperature range for the TMS320F28075PTPQ?

The TMS320F28075PTPQ is qualified for –40°C to 125°C free-air operation and meets AEC Q100 Grade 1 requirements. This rating ensures reliable performance in automotive under-hood environments and industrial enclosures without forced cooling, directly supporting EV charging station and traction inverter deployments where ambient temperatures exceed 85°C.

Does the TMS320F28075PTPQ include hardware support for functional safety certification?

Yes, the TMS320F28075PTPQ is ISO 26262 ASIL B and IEC 61508 SIL 2 certified by TÜV SÜD. It includes hardware safety features such as ECC-protected memory, windowed watchdog timers, missing-clock detection, and hardware BIST-enabling system-level compliance for automotive and industrial safety applications without requiring additional external safety monitors.

How many high-resolution PWM channels does the TMS320F28075PTPQ support?

The TMS320F28075PTPQ supports 16 high-resolution PWM (HRPWM) channels across eight ePWM modules (A/B pairs), delivering <150ps resolution and programmable dead-band. This capability enables precise gate timing for wide-bandgap devices in high-frequency resonant converters and SiC-based traction inverters where nanosecond-level control is essential.

Can the TMS320F28075PTPQ execute code independently on both CPU and CLA cores?

Yes, the TMS320F28075PTPQ features a fully independent Control Law Accelerator (CLA) coprocessor that runs IEEE 754 floating-point code concurrently with the main C28x CPU. The CLA responds to peripheral triggers (e.g., ADC end-of-conversion, PWM timer overflow) and uses dedicated message RAM-enabling true parallel real-time execution without shared resource contention.

What analog input channels are available on the TMS320F28075PTPQ?

The TMS320F28075PTPQ provides up to 17 external analog input channels across three 12-bit ADCs (ADC-A, ADC-B, ADC-D), with dedicated pins including ADCINA0–ADCINA5, ADCINB0–ADCINB5, ADCIND0–ADCIND4, and shared inputs ADCIN14/ADCIN15. Each ADC includes a sample-and-hold circuit and hardware post-processing for real-time signal conditioning.
