The CMA3000
Targets motion measurement & control apps in portable consumer electronics
VTI Technologies at the Consumer Electronics Show (CES) in Las Vegas announces the 3-axis accelerometer, the CMA3000.
Enabled by VTI's RoHS compatible wafer level packaging, which removes the need for a plastic housing, the size of the soldered CMA3000 is 2x2x0.9 mm3. It consumes 10 uA when powered with 1.8 V supply voltage, and is ideal for continuous usage in small battery powered devices, such as mobile phones, gaming devices and sports electronics.
The small size and low power consumption enable designers to innovate with less constrains, opening up new possibilities for accelerometer applications in consumer electronics.

"The 3-axis accelerometer market is booming, and CMA3000's small size and ultra low current consumption will help our customers to differentiate with their accelerometer enabled products within that huge market. Wouldn't it be great, if you could run say your activity monitoring application for 5000h - that's 7 months 24/7 - without the need to change the battery?" says Pekka Kostiainen, Product Manager at VTI.
The CMA3000 is available both in digital and analog versions, with the digital version being optimized for systems requiring low power consumption. Depending on the output sample rate the sensor's current consumption is between 70 and 7 uA, and its embedded interrupt functionality can be used to optimize system power consumption even further.
The analog CMA3000-A01 has three continuous time ratiometric output signals to enable easy integration in systems where AD-converter is available.
