STM32L412KBU6

STM32L412KBU6 is an ARM® based 32bit microcontroller. This ultra-low-power microcontroller is based on the high-performance Arm® Cortex®-M4 32bit 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. This device embeds high-speed memories, a quad SPI flash memories interface (available on all packages) and an extensive range of enhanced I/Os and peripherals connected to two APB buses, two AHB buses and a 32bit multi-AHB bus matrix. This device embeds several protection mechanisms for embedded flash memory and SRAM: readout protection, write protection, proprietary code readout protection and Firewall.
