APEC Product Roundup: BOM and Space Savers
by 
San Jose, Calif. – mCube announced the sampling of its new MC3635 3-axis accelerometer, claiming the industry’s lowest power consumption, in a 1.6- x 1.6-mm land grid array (LGA) package. “The MC3635 will enable developers to design a complete 3-axis inertial solution, with only a single resistor, in less than 1/10th of a square centimeter of space on a printed circuit board,” said mCube. These features make the MC3636 well suited for wearable devices and Internet of Moving Things (IoMT) applications that require significantly extended battery life and very small form factors.
As the newest member of mCube’s MC3600 family of ultra-low-power, high-performance 3-axis accelerometers, the MC3635 is built on the company’s 3D monolithic single-chip MEMS technology platform. With this approach, the MEMS sensors are fabricated directly on top of IC electronics in a standard CMOS fabrication facility. The advantages, said mCube, include smaller size, higher performance, lower cost, and the ability to integrate multiple sensors onto a single chip.
The MC3635 accelerometer consumes less than 0.9 uA of current at 25-Hz output data rate (ODR), which is less than half the power consumption of competing accelerometers, according to the company. To further reduce system power consumption, the device also features an ultra-low-power wake mode that consumes 0.3 uA at 1Hz ODR and sniff mode that consumes only 0.4 uA at 6Hz ODR. These modes are suitable for wearables during periods of rest or inactivity.
The company optimized the MC3635 by increasing its serial peripheral interface (SPI) bus speed and reducing the number of transactions per SPI transfer. These both further extend the battery life of system, said mCube.
Availability: Samples are available to selected lead customers now. General sampling is scheduled for December 2015 with volume production scheduled for the first quarter of 2016.
