stm32f103x4和stm32f103x6表現(xiàn)家庭將高性能ARM Cortex M3?- 32位RISC核心在72 MHz的頻率運行，高速嵌入式存儲器（閃存和SRAM的高達32字節(jié)至6字節(jié)），和增強的I/O和外設(shè)連接到兩APB總線的范圍廣泛。所有器件提供兩個12位ADC，三個通用16位定時器和一個PWM定時器，以及標準和先進的通信接口：最多兩i2cs和SPI接口，三個USB串行外設(shè)接口，和一個可以。

    低密度的STM32F103xx表現(xiàn)家族經(jīng)營從2至3.6 V電源供電。這兩–40 + 85°C溫度范圍和–40 + 105°C擴展溫度范圍是可用的。一套全面的省電模式允許低功耗的應(yīng)用設(shè)計。

    低密度表現(xiàn)的STM32F103xx系列包括四種不同的封裝類型的設(shè)備：36針64針。這取決于設(shè)備的選擇，不同的外設(shè)包括，下面的描述了設(shè)備在這個家庭提出了完整的概述。

    這些特點使得STM32F103xx系列單片機的低密度表現(xiàn)了廣泛的應(yīng)用，如電機驅(qū)動器，應(yīng)用控制，醫(yī)療和手持設(shè)備，PC和游戲外設(shè)，GPS平臺，工業(yè)應(yīng)用，PLC，變頻器，打印機，掃描儀，報警系統(tǒng)，可視對講機，和空調(diào)系統(tǒng)
