The 112 I/O lines and rich peripheral set (CAN, USB OTG, multiple SPI/I²C/UART, plus an external bus interface) make it suitable for industrial control panels, motor drives, and IoT gateways where a BGA package is acceptable. ## Memory and peripheral density The 144-UFBGA (10x10 mm) package is a fine-pitch BGA — not hand-solder friendly. The 112 I/O count demands a multi-layer PCB with via-in-pad or microvia routing. Plan for a dedicated ground plane and decoupling capacitor placement per ST's layout guidelines. For dual-sourcing resilience, ST offers pin-compatible density variants within the STM32L4 series, but no official second-source alternate from another manufacturer is recorded.","metaTitle":"ST STM32L4S9ZIJ6TR ARM Cortex-M4 MCU, 120 MHz, 2 MB Flash","metaDescription":"STMicroelectronics STM32L4S9ZIJ6TR 32-bit MCU, 120 MHz Cortex-M4, 2 MB Flash, 640 KB SRAM, 112 I/O, 144-UFBGA, -40 to 85 °C.
