Microchip aims lowest-power MEMS oscillators at wearables, IoT

These devices, Microchip asserts, withstand 500-times more shock and five times greater vibration than a quartz oscillator; the DSC6000 family is presented as the smallest MEMS MHz oscillator with the lowest power consumption over full frequency range of 2 kHz to 100 MHz.


The single-output DSC6000 MEMS oscillators are suited for use as clock references in small, battery-powered devices such as wearables and Internet of Things (IoT) devices in which small size, low power consumption, and long-term reliability are paramount. They also meet AEC-Q100 for under-bonnet applications.


The oscillators are housed in industry standard 4-pin DFN packages ranging from as small as 1.6 x 1.2 mm up to 7 x 5 mm, and consume 1.3 mA (typical), less than half the current consumption of the lowest-power quartz-based oscillators. They also have a maximum operating temperature range of -40C to +85C and ±25 ppm maximum drift over this range. They can sustain 500 times more shock and five times more vibration than a quartz oscillator, ensuring rock-solid stability in most operating environments.


Microchip’s ClockWorks online configuration tool allows designers to select the right oscillator in terms of frequency, package size, ppm and temperature range and then request samples of that oscillator through the same tool. The TimeFlash field programming kit provides instant frequency generation by fusing the One-Time Programmable (OTP) memory in a blank DSC6000 part that can be ordered separately.


The ClockWorks Configurator is available online at Microchip’s TimeFlash Field Programming Kit that supports the DSC6000 family is available at, priced between $130 to $350. Evaluation boards programmed to customer specifications are available upon request.


The DSC60xx and DSC61xx come in package options: 1.6 x 1.2 mm; 2.0 x 1.6 mm; 2.5 x 2.0 mm in 4-pin VLGA; and 3.2 x 2.5 mm in 4-pin VDFN.
