STM32L4R5QGI6 Description

A family of ultra-low-power microcontrollers (STM32L4+ Series) based on the powerful Arm? Cortex?-M4 32-bit RISC core are the STM32L4R5xx, STM32L4R7xx, and STM32L4R9xx devices. They run at up to 120 MHz of frequency.

All of the Arm? single-precision data-processing instructions and all data types are supported by the Cortex-M4 core's single-precision floating-point unit (FPU). A memory protection unit (MPU) and a full set of DSP (digital signal processing) instructions are also implemented by the CortexM4 core, which increases the security of the program.

These chips include two OctoSPI Flash memory interfaces, a flexible external memory controller (FSMC) for static memories, two high-speed memories (2 Mbytes of Flash memory and 640 Kbytes of SRAM), a flexible external memory controller (FSMC) for static memories (for devices with packages of 100 pins and more), and a wide range of enhanced I/Os and peripherals connected to two APB buses, two AHB buses, and a 32-bit multi-AHB bus matrix.
