STM32系列基于专为要求高性能、低成本、低功耗的嵌入式应用专门设计的ARM Cortex-M3内核。按性能分成两个不同的系列：STM32F103“增强型”系列和STM32F101“基本型”系列。增强型系列时钟频率达到72MHz，是同类产品中性能最高的产品；基本型时钟频率为36MHz，以16位产品的价格得到比16位产品大幅提升的性能，是16位产品用户的最佳选择。两个系列都内置32K到128K的闪存，不同的是SRAM的最大容量和外设接口的组合。时钟频率72MHz时，从闪存执行代码，STM32功耗36mA，是32位市场上功耗最低的产品，相当于0.5mA/MHz。原子stm32开发指南，很好的stm32入门书籍。-STM32 family is based on the ARM Cortex-M3 core designed for embedded applications that require high performance, low cost, low power consumption designed. The performance is divided into two different series: STM32F103 " enhanced"　series and STM32F101 " basic"　series. Enhanced series of clock frequencies up to 72MHz, is the highest performance of similar products　basic clock frequency to 36 MHz, to the price of 16 products significantly enhance the performance of more than 16 products, 16 products the best choice. The two series are built-in flash memory from 32K to 128K, the difference is that the combination of the maximum capacity of the SRAM and peripheral interfaces. At 72MHz, executing from Flash, the STM32 power consumption 36mA 32 the lowest power consumption in the market, equivalent to an impressive 0.5mA/MHz.
