德州仪器msp430超低功耗微控制器的家庭由几个设备具有不同的外围设备针对各种应用程序。架构,结合五低功耗模式,优化达到延长电池寿命在便携式测量的应用。设备功能强大的16位risc cpu、16位寄存器,常数发电机造成最大的代码效率。数控振荡器(dco)允许从低功耗模式唤醒在不到1µs主动模式。

msp430x21x1系列是一种超低功耗的混合信号微控制器与一个内置的16位定时器,通用的模拟比较器,十六个i / o别针。

典型应用包括传感器系统采集模拟信号,转换他们的数字值,然后处理数据显示或传输到主机系统。独立的射频前端传感器是应用程序的另一个领域。模拟比较器提供了斜率a / d转换功能。
