1 MB Flash, 128 KB SRAM — memory budget for a connected sensor node
The official product status is Active, meaning ST continues to manufacture and support this order code. For production planning, this eliminates the single-source obsolescence risk that haunts older STM32F1 or STM32L1 variants. If you need a second-source hedge, the STM32L4 series includes pin-compatible density options in the same UFBGA footprint — the base product number STM32L476 covers a range of Flash and SRAM configurations that share the same ball map.
