For production BOMs that need a second-source option, the STM32L151CBU6A (Cortex-M3, 32 MHz, 64-LQFP) shares the same package footprint and many peripherals, but the core speed and memory are lower — it is a functional alternative only if the application can tolerate the reduced performance. Surface-mount in a 64-LQFP (10x10 mm) with a 0.5 mm pitch.","metaTitle":"STM32L451RET6 STM32L4 MCU, ARM Cortex-M4, 80 MHz","metaDescription":"STMicroelectronics STM32L451RET6 32-bit ARM Cortex-M4 MCU, 80 MHz, 512 KB Flash, 160 KB SRAM, 64-LQFP.
