Texas Instruments TMS320F28069PFPQ

Overview

TMS320F28069PFPQ 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 ePWM (8 HRPWM-capable), and 3.46-MSPS 12-bit ADC - deployed in EV charging station power modules and solar string inverters.

For engineers reviewing the TMS320F28069PFPQ datasheet, TMS320F28069PFPQ pinout, TMS320F28069PFPQ application, or TMS320F28069PFPQ equivalent, key selection criteria include automotive-grade AEC-Q100 qualification (–40°C to 125°C), 80-pin HTQFP PowerPAD™ package, dual-edge HRPWM capability, on-chip temperature sensor, and USB 2.0 device/host support.

Technical Context

The TMS320F28069PFPQ implements a Harvard architecture C28x CPU with atomic operations and unified memory programming, enabling deterministic real-time execution. Its independent 32-bit floating-point CLA offloads control-law computation from the main CPU while sharing DMA-accessible peripherals including ePWM, eCAP, and ADC.

Peripheral integration includes dual-sample-and-hold ADC with ratio-metric VREFHI/VREFLO referencing, analog comparators with 10-bit internal references routed directly to ePWM trip zones, and dual zero-pin oscillators supporting PLL-based clock generation up to 90 MHz - all operating from a single 3.3-V supply without sequencing.

FAQ

What is the maximum operating frequency and instruction cycle time of the TMS320F28069PFPQ?

The TMS320F28069PFPQ operates at a maximum CPU frequency of 90 MHz, delivering an instruction cycle time of 11.11 ns. This timing is achieved using the internal PLL with either the on-chip zero-pin oscillators or an external crystal (1–20 MHz). The deterministic execution model ensures consistent cycle counts for critical control loops in TMS320F28069PFPQ-based motor drives and digital power converters.

Does the TMS320F28069PFPQ support AEC-Q100 qualification and what temperature range does it cover?

Yes, the TMS320F28069PFPQ is AEC-Q100 qualified (Grade 1) for automotive applications and operates across –40°C to 125°C. This qualification covers stress testing for temperature cycling, humidity, ESD, and latch-up per AEC standards. The Q suffix explicitly denotes this automotive qualification, and the device is commonly deployed in TMS320F28069PFPQ-based EV charging and door operator systems requiring extended thermal reliability.

How many ePWM channels does the TMS320F28069PFPQ provide, and which support high-resolution mode?

The TMS320F28069PFPQ provides 16 ePWM output channels across eight modules, with all eight HRPWM-capable channels supporting 150-ps resolution for fine frequency/phase control. These HRPWM channels are essential for soft-switching topologies such as resonant LLC and ZVS converters found in TMS320F28069PFPQ-based onboard chargers and wireless power transfer systems.

What peripheral interfaces are included in the TMS320F28069PFPQ for communication and sensing?

The TMS320F28069PFPQ integrates two SCI/UART modules, two SPI modules, one I²C bus, one eCAN module, one McBSP, and full-speed USB 2.0 (device/host). For sensing, it includes a 12-bit 3.46-MSPS ADC with 16 channels and dual sample-and-hold, three analog comparators with internal 10-bit references, and an on-chip temperature sensor - all accessible to both CPU and CLA in TMS320F28069PFPQ designs.

Is the TMS320F28069PFPQ pin-compatible with other devices in the F2806x family, and what package does it use?

Yes, the TMS320F28069PFPQ uses the 80-pin HTQFP PowerPAD™ package (PFP), matching pinout with TMS320F28069PFP and TMS320F28069M-PFP variants. It shares identical mechanical footprint and thermal pad layout with other PFP-packaged F2806x devices, enabling direct PCB reuse across qualified variants - a key advantage in TMS320F28069PFPQ-based automotive and industrial platforms.
