The 169-UFBGA (7x7 mm) package houses the STM32F429AGH6 ARM Cortex-M4 MCU running at 180 MHz with 1 MB Flash and 256K x 8 RAM.
No date-code or PCN flags to chase today — but as with any BGA device, verify moisture sensitivity level (MSL) before reflow if the parts have been in storage past the floor-life window.
The primary difference is the package. The STM32F429AGH6 comes in a 169-UFBGA (7x7 mm) ball-grid array, while the STM32F429ZIT6 is offered in a 144-pin LQFP. Both share the same Cortex-M4 core at 180 MHz, 1 MB Flash, and 256K x 8 SRAM, but the BGA variant occupies less board area and requires different PCB layout, soldering, and rework processes compared to the QFP.
Within the STM32F4 series, pin-compatible alternatives in the 169-UFBGA package include other density variants of the STM32F429 line. The selection is driven by Flash and RAM requirements: the STM32F429AGH6 sits at the 1 MB Flash / 256K x 8 RAM tier. Lower- or higher-density siblings in the same package footprint are available for projects that need less or more memory, but the core peripheral set (Ethernet, LCD controller, CAN) remains consistent across the family.
