STM32L4R5ZIT6P Description
The STM32L4R5xx, STM32L4R7xx and STM32L4R9xx devices are an ultra-low-powermicrocontrollers family (STM32L4+ Series) based on the high-performanceArm? Cortex?-M4 32-bit RISC core. They operate at a frequency of up to 120 MHz.The Cortex-M4 core features a single-precision floating-point unit (FPU), which supports allthe Arm? single-precision data-processing instructions and all the data types. The CortexM4 core also implements a full set of DSP (digital signal processing) instructions and amemory protection unit (MPU) which enhances the application’s security.
