It is part of the STM32L4 series, designed for applications that need a balance of processing throughput and power efficiency — think motor control, sensor fusion, or human-machine interfaces where the 120 MHz core handles real-time loops and the 320 KB RAM holds multiple data buffers or a small frame store without external memory. ## Lifecycle status — plan the supply now The STM32L4P5CET6 carries an EOL hot lifecycle stage, meaning end-of-life is imminent. Procurement should prepare for a last-time-buy window or identify a replacement. Within the STM32L4 family, pin-compatible density variants exist — for example, the STM32L4P5CET6 shares the same 48-LQFP footprint with other STM32L4P5 devices that offer different Flash/RAM combinations, so a shift to a sibling part may be possible without a board respin. No official successor order code is listed; sourcing through independent distribution remains the channel for bridging supply gaps.","metaTitle":"ST STM32L4P5CET6 ARM Cortex-M4 MCU, 120 MHz, 512 KB Flash","metaDescription":"STM32L4P5CET6 32-bit MCU, 120 MHz Cortex-M4, 512 KB Flash, 320 KB RAM, USB OTG, -40 to 85 °C, 48-LQFP.
