The 112 I/O lines give you room for parallel LCD interfaces or multiple sensor buses without a port expander. ## Peripherals and connectivity — USB OTG, CAN, and more ## Package and mounting — 144-UFBGA layout notes The 144-UFBGA (10x10 mm) package is a fine-pitch BGA — surface-mount only, no socket. It's ROHS3 compliant.","metaTitle":"STM32L4R9ZGJ6 STM32L4R MCU, 120 MHz Cortex-M4, 1 MB Flash","metaDescription":"STM32L4R9ZGJ6 32-bit ARM Cortex-M4 MCU at 120 MHz with 1 MB Flash and 640 KB SRAM.
