The compact footprint suits space-constrained designs, but the 0.5 mm ball pitch calls for a capable PCB fab and assembly house. ## Lifecycle and procurement posture There is no NRND or LTB notice, so it remains qualified for new designs and volume production.","metaTitle":"STM32L471QEI6 ARM Cortex-M4 MCU, 80MHz, 512KB Flash","metaDescription":"STM32L471QEI6 from STMicroelectronics STM32L4 series: 32-bit ARM Cortex-M4 at 80MHz, 512KB Flash, 128KB SRAM, 109 I/O, 132-UFBGA.
