STM32L433RBY6TR 32-Bit ARM Cortex-M4 Microcontroller MCU with 80MHz Speed

STM32L433 is an ultra-low-power microcontroller based on the high-performance Arm® Cortex®-M4 32-bit RISC core operating at frequencies up to 80 MHz. The Cortex-M4 core features a Floating Point Unit (FPU) supporting single precision data-processing instructions and data types, along with a full set of DSP instructions and a Memory Protection Unit (MPU) for enhanced application security.
