STM32L4R9ZIT6 Datasheet PDF - ST Microelectronics

●The STM32L4R5xx devices are an ultra-low-power microcontrollers family (STM32L4+ Series) based on the high-performance Arm® 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 all the 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 a memory protection unit (MPU) which enhances the application"s security.
