STM32L412CBT6P 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.

The STM32L412xx devices include a wide range of enhanced I/Os and peripherals connected to two APB buses, two AHB buses, and a 32-bit multi-AHB bus matrix. They also include high-speed memories (Flash memory up to 128 Kbyte, 40 Kbyte of SRAM), a Quad SPI flash memories interface (available on all packages), and two APB buses, two AHB buses, and a 32-bit multi-AHB bus matrix.
