The STM32F429IGH6: It carries 1 MB of Flash and 256 KB of SRAM, 140 I/O lines, and a peripheral set including Ethernet MAC, CAN 2.0B, USB OTG HS, and a parallel LCD interface.
The base product number STM32F429 covers multiple density and package variants, so a pin-compatible swap exists if the BGA becomes a supply bottleneck.
Internal oscillator means it can boot without an external crystal, though the Ethernet and USB PHY will still need a 25 MHz reference.
The STM32F429IGH6 comes in a 201-ball UFBGA package (10x10 mm), while the STM32F429IGT6 uses an LQFP-176 package with gull-wing leads. The UFBGA saves board area but requires a more complex PCB stack-up and rework process. Both share the same 180 MHz Cortex-M4 core, 1 MB Flash, and 256 KB SRAM, so firmware is binary-compatible between them — only the PCB footprint changes.
Yes. The STM32F429IGH6 is a specific variant within the STM32F429 product family. The base product number STM32F429 covers all density and package options sharing the same core, peripherals, and memory map. Code written for any STM32F429 device will run on this part without modification, provided the linker script accounts for the 1 MB Flash and 256 KB SRAM sizes.
