An internal oscillator keeps the BOM short, though an external crystal can be used when tighter timing is needed. It is not qualified for automotive under-hood (125°C) or extended military environments, but the wide supply tolerance and low-power sleep modes make it a strong fit for field-deployed edge nodes that see seasonal temperature swings. ## Lifecycle and sourcing For new designs, this means no supply-chain risk from a looming EOL.","metaTitle":"STM32L422KBU6 STM32L4 ARM Cortex-M4 MCU, 80 MHz","metaDescription":"STMicroelectronics STM32L422KBU6 32-bit ARM Cortex-M4 MCU, 80 MHz speed, 128 KB Flash, 40K x 8 RAM, -40°C to 85°C, 1.71V-3.6V supply.
