Product details
Overview
TMS320F28075PZPT 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 TMS320F28075PZPT datasheet, TMS320F28075PZPT pinout, TMS320F28075PZPT application, or TMS320F28075PZPT equivalent, key selection criteria include HRPWM resolution for SiC/GaN gate drive timing, ADC simultaneous sampling across three phases, CLA offloading of torque-loop computation, and functional safety documentation support for ASIL B/SIL 2 system integration.
Technical Context
The TMS320F28075PZPT implements a dual-core real-time architecture: the C28x CPU executes main control loops while the CLA handles time-critical tasks like current-loop compensation and PWM update-both running at 120MHz with IEEE 754 single-precision math. Its analog subsystem supports synchronized sampling across three independent 12-bit ADCs with hardware post-processing including windowed comparators and DAC-referenced trip generation.
Peripherals are tightly coupled via dedicated data bus bridges: ePWM modules feature dead-band insertion and TZ fault inputs directly tied to comparator outputs; SDFM channels interface with external ΣΔ modulators for isolated current sensing; and dual CAN controllers (ISO 11898-1 compliant) enable distributed control in traction inverters and energy storage systems.

FAQ
What is the maximum operating junction temperature for the TMS320F28075PZPT?
The TMS320F28075PZPT is rated for –40°C to 105°C junction temperature (TJ) under commercial conditions. This rating applies to the PZP (100-pin HTQFP) package variant and is validated per TI's recommended operating conditions. Thermal design must ensure the exposed PowerPAD™ thermal pad is soldered to a PCB ground plane with sufficient thermal vias to maintain safe junction temperatures during continuous 120MHz operation.
Does the TMS320F28075PZPT support functional safety certification out of the box?
Yes, the TMS320F28075PZPT is ISO 26262 certified up to ASIL B and IEC 61508 certified up to SIL 2 by TÜV SÜD. It includes hardware safety mechanisms such as ECC on flash and RAM, HWBIST, and lockstep-capable peripherals. TI provides a functional safety manual, FMEDA report, and safety analysis documentation to support system-level certification efforts for automotive and industrial applications.
How many high-resolution PWM channels does the TMS320F28075PZPT provide?
The TMS320F28075PZPT provides 16 high-resolution PWM (HRPWM) channels-eight modules with A and B outputs each-delivering 150ps timing resolution. This capability is confirmed for the PZP package in Table 4-1 of the SPRS902K datasheet and enables precise gate driving for SiC and GaN power devices in high-frequency power converters.
Can the TMS320F28075PZPT execute code from RAM while running flash-based firmware?
Yes, the TMS320F28075PZPT supports simultaneous execution from flash and RAM. Its memory map allocates 100KB of on-chip RAM (including 64KB global shared and 36KB local/dedicated), and the boot ROM enables configurable boot modes including RAM-only execution. Critical real-time routines-such as CLA tasks or fast interrupt service-can be loaded into RAM for deterministic zero-wait-state performance.
Is the USB interface on the TMS320F28075PZPT a full-speed or high-speed PHY?
The TMS320F28075PZPT integrates a full-speed USB 2.0 PHY (12 Mbps) with integrated MAC, supporting device-mode operation for firmware updates, debug communication, and host interface functions. It does not include a high-speed (480 Mbps) PHY. The USB module is fully compliant with USB 2.0 specification and supports standard class drivers including CDC ACM for virtual COM port implementation.
