Product details
Overview
TMS320F28075PTPT from Texas Instruments is a 120MHz C28x 32-bit floating-point real-time microcontroller with IEEE 754 FPU, Trigonometric Math Unit (TMU), and independent 120MHz Control Law Accelerator (CLA). It integrates 512KB ECC-protected flash, 100KB RAM (ECC/parity), three 12-bit ADCs (3.1MSPS each), 24 ePWM channels (16 HRPWM), dual CAN, USB 2.0, and CLB for industrial motor control and solar inverter power stages.
For engineers reviewing the TMS320F28075PTPT datasheet, TMS320F28075PTPT pinout, TMS320F28075PTPT application, or TMS320F28075PTPT equivalent, key selection criteria include HRPWM resolution for SiC/GaN gate drive timing, ADC throughput for three-phase current sensing, CLA offload capability for torque-loop execution, and functional safety documentation for ASIL B/SIL 2 system integration.
Technical Context
The TMS320F28075PTPT implements a dual-core real-time architecture: the C28x CPU executes main control tasks while the CLA coprocessor handles time-critical algorithms-both running at 120MHz with IEEE 754 single-precision support. Its analog subsystem delivers simultaneous sampling across three 12-bit ADCs with hardware post-processing including windowed comparators, DAC-referenced trip generation, and S/H per channel.
Control peripherals include 24 ePWM outputs with dead-band and high-resolution A/B channels on eight modules, six eCAP units for precise edge capture, three eQEP interfaces for position feedback, and eight SDFM input channels supporting fast overcurrent detection via comparator filtering. The device supports dual-zone security, boot ROM with peripheral booting, and configurable logic blocks augmenting PWM and capture functionality.

FAQ
What is the maximum operating junction temperature for the TMS320F28075PTPT?
The TMS320F28075PTPT is rated for –40°C to 105°C junction temperature (TJ) under continuous operation. This rating applies to the commercial-grade variant denoted by the 'T' suffix in the temperature grade. Thermal design must ensure the exposed PowerPAD™ thermal pad is soldered to a robust PCB ground plane with sufficient thermal vias to maintain safe junction temperatures under full load.
Does the TMS320F28075PTPT support pin-compatible migration from other F2807x devices?
Yes - the TMS320F28075PTPT shares identical 176-pin HLQFP (PTP) package, pinout, and electrical characteristics with the TMS320F28076PTPT. Software and hardware designs targeting the F28076 can be reused for the F28075 with minor configuration adjustments for ADC count and CLB tile availability. No PCB changes are required for migration between these two PTP variants.
How many high-resolution PWM channels does the TMS320F28075PTPT provide?
The TMS320F28075PTPT provides 16 high-resolution PWM (HRPWM) channels - implemented as A/B pairs across eight ePWM modules. Each HRPWM channel achieves <150ps resolution, enabling precise gate timing for wide-bandgap power devices. Standard ePWM outputs (non-HR) total 24 channels, with HRPWM capability available on both A and B outputs of designated modules.
Is the TMS320F28075PTPT qualified for automotive applications?
No - the TMS320F28075PTPT is the commercial-grade variant (temperature grade 'T'). For automotive use, TI offers the TMS320F28075-Q1, which is AEC-Q100 qualified, rated for –40°C to 125°C free-air temperature, and includes additional automotive-specific test coverage and documentation. The 'PTPT' suffix confirms non-automotive qualification.
What development tools are officially supported for the TMS320F28075PTPT?
Texas Instruments officially supports the TMS320F28075PTPT with C2000Ware SDK, MotorControl SDK, and DigitalPower SDK. Hardware platforms include the TMDXDOCK28075 controlCARD and LAUNCHXL-F28075 LaunchPad. Code Composer Studio v12+ provides full debug, profiling, and real-time analysis capabilities - including CLA-aware debugging and HRPWM waveform visualization.
