The connectivity list includes CANbus, USB OTG, multiple SPI and I²C channels, SAI for audio, and an SDIO interface for external storage. ST lists the STM32L4R5VGT6 as Active (current product status). For a procurement planner, this means the part is still a safe selection for a new BOM line — you are not chasing a disappearing allocation. The base product number STM32L4R5 covers a density range, so if your firmware outgrows 1 MB Flash later, the pin-compatible STM32L4R5xI variants (with 2 MB Flash) are a drop-in swap without a PCB spin. ## Package and supply — board-level fit The 100-LQFP (14x14 mm) is a hand-solderable, inspectable package. The 1.71 V minimum supply allows operation from a single alkaline cell.","metaTitle":"STM32L4R5VGT6 STMicroelectronics MCU, 120MHz Cortex-M4","metaDescription":"STM32L4R5VGT6 32-bit ARM Cortex-M4 MCU, 120MHz, 1MB Flash, 640KB SRAM, 100-LQFP.

It is not a pin-compatible replacement; the STM32L4R5VGT6 offers roughly 4x the core speed, 8x the Flash, and a richer peripheral set. For a true second-source within the same family, look at the STM32L4R5xI variants (same package, 2 MB Flash) or the STM32L4R9xI (with graphics accelerator)."},{"question":"What is the lead time for the STM32L4R5VGT6?","answer":"As an active, current-production part, typical lead times through independent distribution are generally manageable, but current market conditions vary — request a quote for the latest estimate."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32L4R5VGT6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32L4R5VGT6 when reusing this data.
