Description of the STM32L475VET6TR

The STM32L475VET6TR device is an ultra-low-power microcontroller based on the high-performance ARM® Cortex®-M4 32-bit RISC core that operates up to 80 MHz.The Cortex-M4 core features a single-precision floating-point unit (FPU) that supports all ARM single-precision data processing instructions and data types. It also implements a full set of DSP instructions and a Memory Protection Unit (MPU) for increased application security.

The STM32L475VET6TR device embeds high-speed memory (up to 1 Mbyte Flash and 128 Kbytes SRAM), a flexible external memory controller (FSMC) for static memory (for devices in 100-pin packages), a Quad SPI Flash interface (for all packages), and connections to two APB buses, two AHB buses and the 32-bit AHB buses, two AHB buses, and a large number of enhanced I/O and peripherals connected to the 32-bit multi-AHB bus matrix.

The STM32L475VET6TR device embeds multiple protection mechanisms for embedded Flash and SRAM: read protection, write protection, proprietary code read protection, and firewall.
