That 1.71 V floor is the same as the STM32L4's internal brown-out reset threshold, so you don't need an external supervisor for the low-voltage edge — the chip handles its own power-fail sequencing. The base product number is STM32L476, so any PCN or EOL notice from ST would reference that family — keep an eye on the STM32L4 roadmap if you need a drop-in migration path to a higher-density or lower-power variant later. ## 132-UFBGA footprint — layout checklist The 109 I/O count means most of the balls are assigned to GPIO and peripherals; the power and ground balls are distributed across the array, so the PCB stack-up must handle the current density. For rework, a hot-air station with a BGA nozzle and a pre-heater plate is mandatory — don't try this with a standard soldering iron.","metaTitle":"STM32L476QGI6TR STM32L4 MCU, 80MHz Cortex-M4, 1MB Flash","metaDescription":"STMicroelectronics STM32L476QGI6TR 32-bit ARM Cortex-M4 MCU, 80MHz, 1MB Flash, 128KB SRAM, 109 I/O, 132-UFBGA.

The STM32L476QGI6TR in 132-UFBGA offers the full 109 I/O and 1 MB Flash. Software is compatible at the register level, but the pinout and PCB footprint are completely different — a board designed for one cannot fit the other without a layout change."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32L476QGI6TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32L476QGI6TR when reusing this data.
