The STM32L451CCU6 is an STMicroelectronics STM32L4 series 32-bit ARM Cortex-M4 single-core microcontroller running at 80 MHz.
For dual-sourcing resilience, the base product number STM32L451 covers a density and package family — the CCU6 suffix identifies the 256 KB Flash, 48-pin UFQFPN variant, and pin-compatible siblings with different Flash sizes share the same footprint.
