Product details
Overview
TMS320F28075PZPQ 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 up to 9.3MSPS system throughput - deployed in EV traction inverters, solar string inverters, and industrial AC drive control modules.
For engineers reviewing the TMS320F28075PZPQ datasheet, TMS320F28075PZPQ pinout, TMS320F28075PZPQ application, or TMS320F28075PZPQ equivalent, key selection considerations include its AEC Q100–qualified –40°C to 125°C free-air operation, 100-pin HTQFP package with 41 GPIOs, dual CAN 2.0B interfaces, and CLA coprocessor enabling parallel real-time control execution.
Technical Context
The TMS320F28075PZPQ implements a dual-core real-time architecture: the main C28x CPU executes deterministic control loops at 120MHz with hardware-accelerated trigonometric functions, while the independent CLA coprocessor runs concurrent floating-point code at 120MHz to offload time-critical tasks like PWM fault response and ADC post-processing. Both cores share access to on-chip memory and peripherals via dedicated bus bridges.
Its analog subsystem integrates three synchronized 12-bit ADCs (3.1MSPS each), eight windowed comparators with integrated 12-bit DAC references, and three buffered 12-bit DAC outputs - enabling simultaneous phase current/voltage sampling and fast overcurrent trip generation in motor drives. The device supports pin-bootable SPI, SCI, I²C, and CAN interfaces for flexible system communication.

FAQ
What is the operating temperature range for the TMS320F28075PZPQ?
The TMS320F28075PZPQ is qualified to AEC Q100 Grade 1 with a specified free-air temperature range of –40°C to 125°C. This rating applies to the full functional specification and is validated for automotive under-hood applications such as on-board chargers and traction inverters. The device does not specify junction temperature limits separately for the PZPQ variant; design margining should follow TI's thermal guidelines using the provided θJA and θJC values in the datasheet.
Does the TMS320F28075PZPQ support pin-compatible migration from other F2807x devices?
No - the TMS320F28075PZPQ uses a 100-pin HTQFP package (PZP suffix) with 41 GPIOs and a reduced peripheral set compared to the 176-pin PTP variants. While it shares the same core architecture and register map, pin assignments differ significantly between PZP and PTP packages. Migration requires PCB redesign; however, firmware reuse is supported across the F2807x family via TI's C2000Ware SDK.
How many ADC inputs are accessible on the TMS320F28075PZPQ package?
The TMS320F28075PZPQ provides 14 external ADC input pins: ADCINA0–ADCINA5 (6 pins), ADCINB0–ADCINB5 (6 pins), and ADCIN14–ADCIN15 (2 pins). These connect to two of the three integrated 12-bit ADC modules (ADC-A and ADC-B); ADC-D is not routed to pins in the PZP package. All 14 inputs support single-ended operation with internal pulldowns.
Is the CLA coprocessor available and fully functional on the TMS320F28075PZPQ?
Yes - the TMS320F28075PZPQ includes a fully functional 120MHz Control Law Accelerator (CLA) coprocessor identical to that in the PTP variants. It supports IEEE 754 single-precision floating-point instructions, executes independently of the C28x CPU, and responds to the same peripheral triggers (e.g., ADC end-of-conversion, PWM timer events). All CLA memory and messaging resources are present and usable.
What safety certifications apply specifically to the TMS320F28075PZPQ?
The TMS320F28075PZPQ carries ISO 26262 ASIL B and IEC 61508 SIL 2 certification from TÜV SÜD, covering hardware integrity and safety mechanisms including ECC-protected memory, clock failure detection, watchdog timers, and HWBIST. Documentation supporting system-level functional safety design (e.g., FMEDA reports, safety manuals) is available from TI for this exact part number and qualification grade.
