This is not a hand-solderable QFP — it requires a solder-paste stencil, reflow oven, and x-ray inspection for void detection. The board layout must match the WLCSP footprint exactly; no pad fan-out is possible under the balls. It is ROHS3 compliant. The base product number is STM32L4R5, and the series is STM32L4R — a current-generation ultra-low-power family with a roadmap. No successor has been announced, which is normal for an active flagship part.","metaTitle":"STM32L4R5ZIY6TR - STM32L4R 32-bit MCU, 120MHz, 2MB Flash","metaDescription":"STM32L4R5ZIY6TR is a 32-bit ARM Cortex-M4 MCU from STMicroelectronics, 120MHz, 2MB Flash, 640KB RAM, 144-WLCSP.
