Microcontrollers Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when sourcing components. Confirm the exact Flash capacity variant (1 Mbyte) as the STM32F429 family includes other densities. Ensure the package type matches the required PCB footprint for surface-mount assembly. Cross-reference the datasheet revision to confirm peripheral availability and errata status before finalizing design integration.

Microcontrollers Selection Notes

Select this component for applications demanding high throughput with complex graphics or extensive external memory interfacing. The ART Accelerator optimizes code execution speed directly from Flash. Consider the pin count and available GPIOs against interface requirements. Evaluate thermal performance under maximum load conditions given the 180 MHz clock speed and operating temperature range.

Microcontrollers Part Context

This part belongs to the STM32F429xx advanced line within the STM32F4 series. It shares the same core architecture and peripheral set as the STM32F427xx but typically offers higher memory capacities. The VGT6TR designation specifies the 144-pin LQFP package and tape-and-reel delivery format. It serves as a bridge between foundation and advanced lines, offering robust connectivity and multimedia capabilities.

Microcontrollers Replacement Considerations

STM32F429ZGT6TR: Offers identical functionality in a 144-pin LQFP package with potentially different Flash density.

Microcontrollers FAQ
