意法半导体的先进MEMS加速度计包含模拟和数字部分,加速度(量程)高达±400g、电源电压为1.71~3.6V。

加速度计具有高效的节电特性,是超低功耗应用的理想之选。这些特性包括低功耗模式、自动唤醒功能和可用于存储数据的FIFO缓存,从而降低了主处理器负载和系统功耗。

意法半导体的加速度计适于便携式应用(例如手机和PDA),同时满足低功耗与小尺寸的应用。意法半导体最近推出的新一代加速度计在小型化方面取得了巨大进步,封装尺寸仅为2x2x1 mm,并且提供2种管脚封装:14和12引线。

意法半导体的产品还提供面向汽车应用的加速度计,例如AIS32x系列(扩展的温度范围且符合AEC-Q100标准的要求),面向工业类应用的产品,如IISxx产品(属于意法半导体的长生命周期产品,自上市起可持续供货时间长达10年)。

 

MEMS sensors for designs requiring long-term availability

ST launches a new series of MEMS sensors that will stay in production for ten years starting from their date of introduction. These products take part to the 10 years' longevity commitment program, which assures, on selected parts, continuity and stability of supply for ST customers, especially those that design industrial applications and require long-term product availability.
The first 3 sensors joining the program are two new 3-axis accelerometers (IIS328DQ and IIS2DH) and a 3-axis gyroscope (I3G4250D) specifically intended for harsh industrial environments often characterized by extended temperature ranges and a high level of shocks and vibrations.
