The device features multiple low-power modes: Standby at 290nA (with RTC), Stop at 0.5uA (with RTC), Low-Power Run at 9uA, and Run at 245uA\/MHz. Peripherals include a 12-bit 1Msps ADC with up to 24 channels, dual 12-bit DAC, up to 5 USARTs, 3 SPIs, 2 I2Cs, USB 2.0 full-speed, LCD controller for segment displays, and 2 comparators. The ultra-low-power architecture makes it ideal for battery-powered and energy-harvesting applications.","working_principle":"The STM32L151RET6 uses ST's ultra-low-power Cortex-M3 platform with multiple power domains. (1) CPU: The ARM Cortex-M3 core executes Thumb-2 instructions at up to 32MHz, providing 1.25 DMIPS\/MHz performance. The NVIC supports up to 48 interrupts with 16 priority levels. (2) Power Management: Separate power domains for CPU, Flash, SRAM, and peripherals allow selective power-down. The voltage regulator supports 1.8V to 3.6V with an internal step-down converter. Low-power modes include Sleep (CPU stopped, peripherals running), Stop (all clocks stopped, SRAM retained, fast wakeup), and Standby (only RTC and backup registers retained, 290nA). (3) Analog: The 12-bit SAR ADC converts at 1Msps with hardware oversampling for improved resolution. Two 12-bit R-2R DACs generate analog waveforms. (4) LCD Controller: The built-in LCD controller drives up to 8x40 segments directly without external driver IC.","pin_description":"
