Product details

The STM32H7B3NIH6Q: ARM Cortex-M7 MCU at 280 MHz with 1.4 MB RAM.

If you are supporting a production line that already qualifies this BGA footprint, the immediate task is to secure enough devices for the remaining build horizon.

216-ball BGA — layout and assembly notes

The 216-TFBGA package (13x13 mm) is a fine-pitch BGA — not a hand-solderable part. The board requires a multilayer stack-up with microvias or blind vias to route the 116 I/O and the supply rails. Operating temperature covers -40 to 85 °C, so the assembly must survive industrial reflow profiles.

Frequently asked questions

Is STM32H7B3NIH6Q obsolete?

Buyers need to know if the part is end-of-life to avoid design or supply chain risks.

What is the alternative for STM32H7B3NIH6Q?

Finding a drop-in replacement or equivalent is critical when the original is obsolete or unavailable.

Where can I buy STM32H7B3NIH6Q?

Sourcing buyers need to locate authorized distributors with stock or lead time information.

What is the datasheet for STM32H7B3NIH6Q?

Design engineers validate pin compatibility, electrical characteristics, and design-in requirements from the official datasheet.

What is the price of STM32H7B3NIH6Q?

Pricing information is essential for BOM cost analysis and procurement decisions.

Is STM32H7B3NIH6Q in stock anywhere?

Real-time inventory visibility prevents production delays and expedites purchasing for both small and large volumes.
