Product details

144-LQFP — rework-friendly, inspectable, and board-practical

Housed in a 144-LQFP with a 20x20 mm body, this is a QFP with visible gull-wing leads on all four sides. No BGA balls, no hidden joints — a hot-air station and tweezers can lift and replace it without X-ray inspection. The 0.5 mm pitch is fine enough for dense routing but still forgiving under a microscope.

No external boost converter needed for the core — just a clean rail and decoupling.

Industrial temperature range — factory-floor and outdoor rated

It is not AEC-Q100 qualified, so it is not the pick for under-hood automotive, but it handles the vast majority of commercial and industrial environments.

Frequently asked questions

What is the core architecture of STM32L4R7ZIT6?

It uses a 32-bit ARM Cortex-M4 core with single-precision FPU and DSP instructions, running at up to 120 MHz. This is the same core used across the STM32L4 series, so code from other L4 parts ports with minimal clock-tree adjustment.

Does STM32L4R7ZIT6 have a pin-compatible alternative in the same family?

The STM32L4R series includes multiple density and package variants that share the same 144-LQFP footprint. The base product number STM32L4R7 covers this specific Flash/RAM combination; stepping to a higher-density sibling (STM32L4R9) or lower-density option (STM32L4R5) within the same 144-pin package is a direct swap on the board, but each has different memory sizes and peripheral counts that must match the firmware image.
