Product Description Of STM32L412CBT6
The STM32L412CBT6 is an ultra-low-power 32-bit microcontroller (MCU) developed by STMicroelectronics, based on the high-performance Arm® Cortex®-M4 core, operating at a maximum frequency of 80MHz, and featuring an integrated floating-point unit (FPU) and digital signal processing (DSP) instruction set, making it ideal for high-efficiency embedded system designs. The STM32L412CBT6 offers 128KB of Flash memory and 40KB of SRAM, supports various communication interfaces (such as I²C, SPI, UART, USB), and is widely used in IoT, smart home, medical devices, and industrial control applications.

Key Features Of STM32L412CBT6
Ultra-low power consumption design: The STM32L412CBT6 uses ST's proprietary low-leakage process, achieving power consumption as low as 28μA/MHz in run mode (SMPS mode) and just 32nA in standby mode, making it ideal for battery-powered devices.
High-performance Cortex-M4 core: The STM32L412CBT6 supports FPU and DSP instructions, making it suitable for real-time signal processing applications such as sensor data acquisition and motor control.
Rich peripheral resources: The STM32L412CBT6 integrates 2 12-bit ADCs (5 Msps), 1 operational amplifier, multiple timers (PWM, RTC), and a capacitive touch sensing interface.
Enhanced security: The STM32L412CBT6 features an on-chip memory protection unit (MPU), hardware encryption engine, and true random number generator (TRNG) to enhance system security.
Compact packaging: The STM32L412CBT6 is available in a 48-pin LQFP (7×7mm) package, ideal for space-constrained designs.
