STM32L412K8U6 Description

The STM32L412xx devices are ultra-low-power microcontrollers built on the powerful 32-bit RISC Arm? Cortex?-M4 core that operates 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.

High-speed memories (Flash memory up to 128 Kbyte, 40 Kbyte of SRAM), 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 a 32-bit multi-AHB bus matrix are all included in the STM32L412xx devices. The STM32L412xx devices have readout protection, write protection, proprietary code readout protection, and Firewall as some of the inbuilt Flash memory and SRAM protection techniques.
