The 83 I/Os in a 100-LQFP package give you enough pins to route a parallel display, a camera interface, and a CAN bus alongside USB OTG and multiple SPI/I²C peripherals, all without multiplexing conflicts on the first pass. The ROHS3 compliance is current, so no conflict with EU or California regulatory updates. ## 100-LQFP — rework-friendly footprint The 100-LQFP (14x14 mm body) is a gull-wing leaded package. No underfill required, no X-ray inspection needed after reflow. ## Peripheral set — what connects without glue Connectivity covers CANbus, USB OTG, multiple SPI and I²C channels, plus SAI for audio and EBI/EMI for external parallel memory or a display controller.","metaTitle":"STM32L4S5VIT6 STM32 MCU, ARM Cortex-M4, 120 MHz, 2 MB Flash","metaDescription":"STM32L4S5VIT6 32-bit ARM Cortex-M4 MCU at 120 MHz with 2 MB Flash and 640 KB SRAM.

The L4S part also offers more I/Os (83 vs 37), USB OTG, and a wider supply range down to 1.71 V.
