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.
The ARM Cortex-M4 core runs at 80 MHz. Program memory is 256 KB of Flash, and SRAM is 160K x 8. This combination handles real-time control firmware with moderate data buffering.
Yes, the STM32L4 family supports SWD (Serial Wire Debug) which is the protocol used by ST-Link programmers. The debug interface is available on the SWDIO and SWCLK pins.
