STM32L452RET6P Description
The STM32L452xx devices are ultra-low-power microcontrollers built on the powerful 32-bit RISC Arm? Cortex?-M4 core that operates at up to 80 MHz. The Cortex-M4 core features a Floating point unit (FPU) single precision which supports all Arm? single-precision data-processing instructions and data types. Additionally, it incorporates a memory protection unit (MPU) that improves program security together with the whole range of DSP instructions.
