Product details

280 MHz Cortex-M7 with 2 MB Flash — what this buys the design

It carries 2 MB of Flash and 1.4 MB of RAM on-chip, which means many embedded GUI, motor-control, and sensor-fusion applications can run without external memory. The 132-WLCSP package (4.57x4.37 mm) saves board area but requires an SMT line with fine-pitch capability — this is not a hand-solderable part.

Peripheral set and connectivity

The 17x16-bit ADC and 3x12-bit DAC channels cover analog front-end needs without an external converter.

Operates from 1.62 V to 3.6 V, covering both 1.8 V and 3.3 V logic rails. An internal oscillator reduces external BOM count.

Frequently asked questions

What are the alternatives or equivalent parts to STM32H7B3QIY6QTR?

Within the STM32H7B3 family, the base product number STM32H7B3 covers multiple package and memory options. For a pin-compatible alternate in a larger package, check the STM32H7B3xI series in LQFP or BGA variants — the WLCSP is unique to this ordering code.
