Housed in a 100-LQFP package (14x14 mm body), surface-mount soldering with standard reflow profiles. The 83 I/O are accessible on a 0.5 mm pitch; the exposed pad (if present on this variant) should be connected to ground with thermal vias for best heat transfer. No special bake is required if the moisture barrier bag is intact — MSL 3 is typical for this package family.
There is no last-time-buy risk for new designs.
Within the STM32L4 series, the STM32L4A6xx family shares the same pinout across density options. For a lower Flash or SRAM variant, the STM32L4A6RG (1 MB Flash, 320 KB SRAM) is functionally identical; the STM32L4R5 or STM32L4S5 families offer higher performance but may differ in peripheral set and package options. Verify the specific order code against your BOM for exact compatibility.
