STM32F429IGT6

STM32F429IGT6 is the LQFP-176 ordering code for the STMicroelectronics STM32F429 microcontroller, listed as Active in the quality table of the maker’s product page, with a 10-year longevity commitment starting 2026-01-01. The code decodes as I for the 176-pin package and G for 1 MB of Flash: an Arm Cortex-M4 core with DSP and FPU at 180 MHz, ART and Chrom-ART accelerators and an FMC with SDRAM support, on a 1.8 V to 3.6 V supply, industrial grade over -40 °C to +85 °C, in a 24 × 24 mm LQFP. The selection point is the display-and-memory step of the F4 line: the graphics acceleration and the external SDRAM interface serve HMI panels that smaller F4 codes cannot drive without extra glue logic. Selection advice: the longevity commitment belongs to this code’s quality record - for long-life industrial programs keep the full IGT6 code in the BOM rather than a pin-count sibling, because Flash size and package are both encoded in it. Parameters verified against the ST STM32F429 product page and the maker’s eStore page for this exact code.
