280 MHz Cortex-M7 with 2 MB Flash and 1.4 MB RAM
It belongs to the STM32H7 series and is built for high-throughput applications — think motor drives, human-machine interfaces, industrial controllers, and audio processing where you need the core to keep up without external memory.
The supply range of 1.62 V to 3.6 V covers both 1.8 V and 3.3 V logic rails, so you can run the core at the low end for power-sensitive nodes and still drive 3.3 V peripherals.
Package and footprint considerations
Housed in a 201-UFBGA (176+25 balls, 10x10 mm body), this is a fine-pitch BGA — 0.5 mm ball pitch typical for the STM32H7A3 family. The PCB layout needs a microvia-capable fab and careful fanout; the 25 extra balls in the centre pad are mostly power and ground, which helps with decoupling but adds to the via count. Plan for a 4-layer board minimum, and confirm the moisture sensitivity level (MSL 3 is common for this package class) before the reflow profile.
The base product number STM32H7A3 covers a range of Flash and RAM options in the same package, so if the 2 MB / 1.4 MB variant fits, the supply pipeline is well established.
