Product details
Overview
TMS320F28069MPZPQ from Texas Instruments is a 90-MHz C28x-core real-time microcontroller with integrated FPU, CLA, and VCU, designed for closed-loop motor control and digital power conversion. It delivers 11.11-ns instruction cycle time, 128KB flash, 50KB RAM, 16-channel 12-bit ADC at 3.46 MSPS, and 16 ePWM outputs (8 HRPWM-capable), deployed in EV charging station power modules and solar string inverters.
For engineers reviewing the TMS320F28069MPZPQ datasheet, TMS320F28069MPZPQ pinout, TMS320F28069MPZPQ application, or TMS320F28069MPZPQ equivalent, key selection criteria include AEC Q100 qualification (–40°C to 125°C), HTQFP-100 PowerPAD™ package thermal performance, CLA-accelerated control law execution, dual-sample-and-hold ADC timing, and eCAN/USB 2.0 interface availability.
Technical Context
The TMS320F28069MPZPQ implements a Harvard bus architecture with atomic C28x CPU instructions and unified memory programming. Its CLA operates independently of the main CPU to execute floating-point control loops, while the VCU extends instruction set support for complex math, CRC, and Viterbi operations-enabling deterministic real-time response in servo drive control.
Peripheral integration includes three eQEP modules for position feedback, four HRCAP units for precise edge capture, and analog comparators with internal 10-bit references routed directly to ePWM trip zones-supporting fast overcurrent protection in AC drive power stage modules without CPU intervention.

FAQ
What is the operating temperature range and qualification status of the TMS320F28069MPZPQ?
The TMS320F28069MPZPQ is rated for –40°C to 125°C and is AEC Q100 qualified for automotive applications. This qualification covers stress testing for temperature cycling, humidity bias, and ESD robustness-making it suitable for under-hood EV charging modules and automotive OBCs where reliability under thermal extremes is mandatory. The "Q" suffix explicitly denotes this qualification.
Does the TMS320F28069MPZPQ support USB functionality, and what modes are available?
Yes, the TMS320F28069MPZPQ integrates a full-speed USB 2.0 peripheral supporting both device and host modes. Pins 26 (USB0DP) and 27 (USB0DM) provide the differential pair with on-chip PHY-enabling firmware updates, debug communication, and host-side data logging without external transceivers. USB is confirmed present in the F28069M variant per TI's Device Comparison table.
How many ePWM channels does the TMS320F28069MPZPQ provide, and which support high-resolution operation?
The TMS320F28069MPZPQ provides 16 ePWM channels across eight modules, with 8 channels capable of high-resolution PWM (HRPWM) operation. These HRPWM channels deliver 150-ps resolution for precise dead-time control and frequency modulation-critical for SiC/GaN-based power stages in solar PCS and wireless charging systems.
What analog-to-digital converter specifications does the TMS320F28069MPZPQ include?
The TMS320F28069MPZPQ features a 12-bit dual sample-and-hold ADC with 3.46 MSPS throughput and 16 input channels. It supports ratio-metric VREFHI/VREFLO references and achieves 289-ns conversion time. The ADC is DMA-accessible and optimized for low-latency sampling-essential for synchronous current sensing in 3-phase motor drives and digital power control loops.
Is the TMS320F28069MPZPQ pin-compatible with other F2806x family members, and what package does it use?
The TMS320F28069MPZPQ uses the HTQFP-100 PowerPAD™ package (PZP), 14.0 mm × 14.0 mm, with exposed thermal pad. It shares pinout compatibility with other PZP-packaged F2806x variants like TMS320F28069PZP and TMS320F28069M-PZP-but not with PN/PFP (80-pin) or non-Q1 variants due to differing temperature-rated bonding wires and qualification-specific test coverage.
