STM32L4A6AGI6 Description

The STM32L4A6xG devices are ultra-low-power microcontrollers built around the powerful 32-bit RISC Arm? Cortex?-M4 core that can operate at up to 80 MHz. A floating point unit (FPU) single precision is a characteristic of the Cortex-M4 core that supports all Arm? single-precision data-processing instructions and data formats. Additionally, it incorporates a memory protection unit (MPU) that improves program security together with the whole range of DSP instructions. The STM32L4A6xG devices include high-speed memories (including 1 Mbyte of flash memory and 320 Kbyte of SRAM), a flexible external memory controller (FSMC) for static memories (for devices with packages of 100 pins and more), a Quad SPI flash memories interface (available on all packages), and a wide variety of enhanced I/Os and peripherals connected to two APB buses, two AHB buses, and other buses.

The STM32L4A6xG devices incorporate readout protection, write protection, proprietary code readout protection, Firewall, and other protective methods for embedded flash memory and SRAM.
