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.","metaTitle":"STM32L4R7ZIT6 ARM Cortex-M4 MCU, 120 MHz, 2 MB Flash","metaDescription":"STMicroelectronics STM32L4R7ZIT6 32-bit ARM Cortex-M4 MCU at 120 MHz with 2 MB Flash and 640 KB SRAM in 144-LQFP.

This is the same core used across the STM32L4 series, so code from other L4 parts ports with minimal clock-tree adjustment."},{"question":"Does STM32L4R7ZIT6 have a pin-compatible alternative in the same family?","answer":"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."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32L4R7ZIT6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32L4R7ZIT6 when reusing this data.
