特性介绍：
STM32L151/152器件利用Cortex-M3内核和频率介于32 kHz至32 MHz的CPU时钟扩展了超低功耗理念，并且不会降低性能。除了动态运行和低功耗运行模式以外，还有另外2种超低功耗模式为您带来了极低的功耗，同时还能保持RTC、后备寄存器内容与低压检测器继续工作。 STM32L151/152器件面向医疗、工业和消费类应用，其主要特性为片上集成的快速
12位1 MSPS ADC、USB 2.0 FS和电容式触摸感应模块。您可以利用SDIO和FSMC接口扩展存储容量。 为了减少应用成本和设计时间，STM32L151/152还提供了具有8x40段的集成式LCD驱动器。 STM32L151/152系列具有32~512KB Flash，采用48~144引脚封装。
The ultra-low-power STM32L151xC and STM32L152xC devices incorporate the connectivity power of the universal serial bus (USB) with the high-performance ARM®Cortex®-M3 32-bit RISC core operating at a frequency of 32 MHz (33.3 DMIPS), a memory protection unit (MPU), high-speed embedded memories (Flash memory up to 256 Kbytes and RAM up to 32 Kbytes) and an extensive range of enhanced I/Os and peripherals connected to two APB buses. The STM32L151xC and STM32L152xC devices offer two operational amplifiers, one 12-bit ADC, two DACs, two ultra-low-power comparators, one general-purpose 32-bit timer, six general-purpose 16-bit timers and two basic timers, which can be used as time bases. Moreover, the STM32L151xC and STM32L152xC devices contain standard and advanced communication interfaces: up to two I2Cs, three SPIs, two I2S, three USARTs and an USB. The STM32L151xC and STM32L152xC devices offer up to 23 capacitive sensing channels to simply add a touch sensing functionality to any application. They also include a real-time clock and a set of backup registers that remain powered in Standby mode. Finally, the integrated LCD controller (except STM32L151xC devices) has a built-in LCD voltage generator that allows to drive up to 8 multiplexed LCDs with the contrast independent of the supply voltage. The ultra-low-power STM32L151xC and STM32L152xC devices operate from a 1.8 to 3.6 V power supply (down to 1.65 V at power down) with BOR and from a 1.65 to 3.6 V power supply without BOR option. They are available in the -40 to +85 °C and -40 to +105 °C temperature ranges. A comprehensive set of power-saving modes allows the design of low-power applications.
