Product details

The STM32H7B3ZIT6 carries 2 MB of Flash and 1.4 MB of RAM on-chip. The 112 I/O and peripheral set include CANbus, USB OTG, a camera interface, and an LCD controller.

The 144-LQFP (20x20 mm) package is a standard QFP footprint — hand-solderable, inspectable under a microscope, and reworkable with hot air. No hidden BGA voids, no X-ray inspection needed. The 112 I/O break out on four sides, so a four-layer board with a ground plane can route most signals without micro-vias.

Supply range and power-on behaviour

Operates from 1.62 V to 3.6 V. The built-in brown-out detect and POR eliminate the need for an external supervisor on most boards.

Sourcing and lifecycle posture

STMicroelectronics lists the STM32H7B3ZIT6 as Active (current production).

Frequently asked questions

What is the maximum clock speed of STM32H7B3ZIT6?

The core runs at 280 MHz, driven by the ARM Cortex-M7 with an internal oscillator or external clock source.

Is STM32H7B3ZIT6 pin compatible with STM32H7B3IIT6?

Yes, both share the same 144-LQFP package and base product number STM32H7B3. The IIT6 variant is a drop-in second source for dual-sourcing the BOM.
