No last-time-buy notice, no PCN for discontinuation. The STM32L4 series has broad second-source options within the family (pin-compatible density variants), but the L433VCI3 itself is the sweet spot for mid-range Flash and SRAM — no need to oversize to the 512 KB or 1 MB parts unless the firmware grows.","metaTitle":"STM32L433VCI3 STM32L4 MCU, ARM Cortex-M4 80MHz, 256KB Flash","metaDescription":"STM32L433VCI3 from STMicroelectronics: ARM Cortex-M4 32-bit MCU, 80MHz, 256KB Flash, 64KB SRAM, 1.71V–3.6V, -40°C to 125°C.
