STM32L4A6ZGT6

STM32L4A6ZGT6 is an ultra-low-power microcontroller based on the high-performance Arm® Cortex®-M4 32-bit RISC core operating at a frequency of up to 80MHz. The Cortex-M4 core features a Floating point unit (FPU) single precision 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) which enhances application security. It embeds high-speed memories (1Mbyte of flash memory, 320Kbyte 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 and an extensive range of enhanced I/Os and peripherals connected to two APB buses, two AHB buses and a 32-bit multi-AHB bus matrix. It also embeds several protection mechanisms for embedded flash memory and SRAM: readout protection, write protection, proprietary code readout protection and Firewall.
