Texas Instruments TMS320F28075PTPQR

Overview

TMS320F28075PTPQR 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 power conversion systems.

For engineers reviewing the TMS320F28075PTPQR datasheet, TMS320F28075PTPQR pinout, TMS320F28075PTPQR application, or TMS320F28075PTPQR equivalent, key selection criteria include real-time computational throughput (dual-core C28x+CLA), analog subsystem concurrency (3×ADC + 8×CMPSS + 3×DAC), functional safety certification (ISO 26262 ASIL B, IEC 61508 SIL 2), and thermal performance in HLQFP-176 PowerPAD packaging.

Technical Context

The TMS320F28075PTPQR implements a tightly coupled dual-execution architecture: the main C28x CPU and CLA coprocessor both run at 120MHz, share memory via 128-word message RAM, and coordinate through hardware-triggered task dispatch. Its analog subsystem enables simultaneous sampling across three independent 12-bit ADCs with hardware post-processing (offset calibration, windowed compare, trip generation) and direct PWM fault response via 8 comparator subsystems (CMPSS).

Control peripherals include 24 ePWM channels-16 supporting high-resolution A/B edge placement-and integrated dead-band generation, six eCAP modules for precise timing capture, three eQEP interfaces for position feedback, and eight SDFM input channels with parallel filtering for sigma-delta sensor interfacing. All are accessible on the 176-pin HLQFP package with full GPIO multiplexing.

FAQ

What is the maximum operating frequency of the TMS320F28075PTPQR CPU and CLA?

The TMS320F28075PTPQR features a C28x CPU and a Control Law Accelerator (CLA) both running at 120MHz. This dual-execution capability enables concurrent real-time processing-such as field-oriented control in the CLA while the CPU handles communications and diagnostics-without resource contention. The 120MHz clock is derived from an internal PLL fed by either an external crystal or the on-chip 10MHz oscillator.

Does the TMS320F28075PTPQR support functional safety standards out of the box?

Yes, the TMS320F28075PTPQR is ISO 26262 ASIL B and IEC 61508 SIL 2 certified by TÜV SÜD. It includes hardware safety mechanisms such as ECC on flash and RAM, Hardware Built-in Self Test (HWBIST), lockstep-ready peripherals, and a comprehensive safety manual. These features allow system integrators to achieve end-equipment certification without requiring additional external safety monitors.

How many ADC modules does the TMS320F28075PTPQR integrate, and what is their combined throughput?

The TMS320F28075PTPQR integrates three independent 12-bit analog-to-digital converters (ADC-A, ADC-B, ADC-D), each capable of 3.1 million samples per second (MSPS). With hardware-synchronized sampling and overlapping conversion windows, the device achieves up to 9.3MSPS total system throughput-sufficient to sample all three phases of a motor drive simultaneously at high resolution and update control loops every 100ns.

What package type and thermal characteristics apply to the TMS320F28075PTPQR?

The TMS320F28075PTPQR uses a 176-pin PowerPAD™ Thermally Enhanced Low-Profile Quad Flatpack (HLQFP), designated by the "PTP" suffix. Its exposed thermal pad must be soldered to a PCB ground plane to achieve optimal thermal performance-typical junction-to-board thermal resistance is ≤2.5°C/W in standard 4-layer board layouts. The device is rated for –40°C to 105°C junction temperature (T grade).

Can the TMS320F28075PTPQR replace the TMS320F28076PTPQR in existing designs?

The TMS320F28075PTPQR is pin-compatible with the TMS320F28076PTPQR in the same HLQFP-176 package and shares identical CPU, CLA, memory, ADC, PWM, and peripheral specifications. However, the F28076 includes 4 CLB tiles and full 97 GPIO access, whereas the F28075 provides 0 CLB tiles and 88 usable GPIOs. Replacement is feasible if the design does not rely on CLB logic or the additional GPIOs.
