This is an STM32F412, part of the STM32F4 series built around an ARM Cortex-M4 core with FPU, clocked at 100 MHz. The 100 MHz clock means the core can sustain around 125 MIPS (Dhrystone 2.1), enough for sensor fusion or audio processing without an external DSP.
Within the STM32F4 family, the STM32F412VGT6TR is a specific density and package variant. The STM32L151CBU6A is a different series (STM32L1 ultra-low-power, Cortex-M3 at 32 MHz) and is not a pin-compatible or functional equivalent — it targets a different power/performance trade-off. For a direct second source, consider other STM32F412 parts in the same 100-LQFP footprint with matching Flash/RAM, or the STM32F413 series which adds more SRAM.
