The 2 MB Flash gives firmware teams room for OTA staging, over-the-air update images, and rich application code without density anxiety. ## Peripheral set and I/O count — what connects where The 100-LQFP (14x14 mm) package is a hand-solderable, inspectable footprint — no BGA rework station needed for prototyping or low-volume production. The tray shipping medium matches pick-and-place feeders that handle LQFP-100.","metaTitle":"STM32L4R5VIT6 STM32 MCU, 120MHz Cortex-M4, 2MB Flash","metaDescription":"STMicroelectronics STM32L4R5VIT6 32-bit ARM Cortex-M4 MCU at 120MHz with 2MB Flash and 640KB SRAM in 100-LQFP.
