Working Principle

The STM32L152CBT6 is based on an ARM Cortex-M3 core and offers several power management options and support of the ARM® Cortex®-M3 core Trace MacrocellTM (TMC) debug and trace technology.At the heart of the STM32L152CBT6 is the 32-bit ARM Cortex-M3 processor. The Cortex-M3 processor is a powerful RISC processor designed for low power applications. It supports two design modes: a high-performance mode and a low-power mode. The processor can switch between the two modes based on the application, allowing it to offer high performance when more power is needed, and also low power when not in execution. The processor operates with up to 72MHz clock frequency and features all the standard ARM instructions, as well as single-cycle DSP instructions.The microcontroller also features a range of on-chip peripherals such as a precision analog-to-digital converter (ADC), universal sync-serial port (USART), serial peripheral interface (SPI), I2C and a 16-bit timer. The peripherals can be used to control various components and enable the system to access and control external devices.The microcontroller also offers several power management options such as low power run mode and standby mode. The low power run mode allows the processor to run at a lower clock frequency, reducing the power consumption. The Standby mode reduces the processor operating voltage, allowing it to enter a deep sleep state, which further reduces the power consumption.
