Housed in a 169-ball UFBGA measuring 7x7 mm, the STM32H743AII6 is a surface-mount device rated for industrial temperature range (-40 to 85 °C). The small footprint suits space-constrained designs, but the BGA pitch demands careful PCB layout and X-ray inspection after reflow.
ST lists the STM32H743AII6 as an active product.
The core runs at 480 MHz, which is the top speed grade in the STM32H7 series.
The suffix difference typically indicates a package variant. The STM32H743AII6 comes in a 169-UFBGA (7x7 mm) package; the STM32H743II6 is a 176-pin LQFP. Pin count and footprint differ, so they are not drop-in replacements.
