The ball pitch is sub-0.8 mm, so the PCB requires at least four layers with microvias for fanout. ## Active lifecycle — no near-term EOL risk ST lists the STM32L4S9ZIJ6 with an active product status.","metaTitle":"STM32L4S9ZIJ6 ARM Cortex-M4 MCU, 120 MHz, 2 MB Flash","metaDescription":"STMicroelectronics STM32L4S9ZIJ6 32-bit MCU: ARM Cortex-M4 at 120 MHz, 2 MB Flash, 640 KB SRAM, 112 I/O, 144-UFBGA.
