STM32L433RCT3 Description

The STM32L433RCT3 is a low-power microcontroller based on the high-performance Arm? Cortex?-M4 32-bit RISC core that operates at up to 80 MHz.

The Cortex-M4 core includes a single-precision floating point unit (FPU) that supports all Arm? single-precision data-processing instructions and data formats. It also has a full set of DSP instructions and a memory protection unit (MPU), which improves application performance.
