Microcontrollers Procurement Notes

Verify the specific suffix 'BGT6' corresponds to the 208-pin LQFP package variant when ordering. Confirm that the required pin count matches your PCB layout, as this model differs from the 176-pin IGT6 version. Ensure compatibility with the 1.7 V to 3.6 V supply voltage range for your target application environment.

Microcontrollers Selection Notes

Select this model if your design requires the 208-pin form factor for additional peripheral access compared to smaller packages. The inclusion of the Ethernet MAC and SDRAM interface makes it suitable for complex graphical user interfaces. Consider the ART Accelerator benefits for code execution speed if performance optimization is critical.

Microcontrollers Part Context

This component belongs to the STM32F429xx high-performance advanced line within the STM32 family. It shares the same core architecture and many peripherals with the STM32F427xx series but typically offers higher memory capacities. The BGT6 designation specifically identifies the 208-pin LQFP packaging option for mass production.

Microcontrollers Replacement Considerations

STM32F429IGT6: Offers identical core functionality but utilizes a 176-pin LQFP package, requiring PCB redesign.
