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.
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.
