STM32L476 in STM32 Family
The STM32L476 sub-family from STMicroelectronics is a series of ultra-low-power microcontrollers based on the high-performance Arm Cortex-M4 32-bit RISC core. Operating at frequencies up to 80 MHz, these devices balance computational power with extreme energy efficiency. They are designed for power-sensitive applications requiring floating-point math, featuring an integrated FPU and DSP instructions, alongside a rich set of peripherals like an integrated LCD controller and USB OTG support.

Variants within the STM32L476 line primarily differ based on flash memory density, ranging from 256KB to 1MB, and package pin counts from 64-pin LQFP to 144-pin BGA. Higher pin-count versions offer more I/O and dedicated peripheral access, such as the full 8x40 LCD segment support or additional serial interfaces, while smaller packages prioritize footprint for space-constrained wearable designs.
