Micro Crystal 32.768 kHz oscillator module consumes less power

 Advanced Crystal Geometry leads to even smaller package

Grenchen, Switzerland, March 8 2017 – Micro Crystal, the leading provider for quartz crystals, oscillators, OCXOs and Real-Time Clocks for the world's leading electronics industry now offers the popular oscillator in the advanced tiny package of just 1.2 * 2.0 * 0.7 mm. This hermetically sealed package hosts the integrated circuit together with the XTAL. It withstands harsh environmental condition. Aside the large supply voltage range it features very low power consumption. In active mode it draws as low as 1 μA driving one CMOS load. Since the oscillator is running also in stand-by mode (i= 0.45 μA) the accurate frequency is available instantaneously, no delayed startup time, as typical e.g. for AT-oscillator, must be cared for. Through factory calibration the accuracy is superior to solutions with external XTAL.

The wide supply voltage range of 1.6 to 5.5 V combined with the large operating temperature range of -40°C to + 85°C, low power consumption and small package size makes it ideal for future applications:


  •   Wearables and Activity Bands

  •   IoT, Smart Pens,

  •   Industrial Computing, Single-board controller

  •   Health Care devices

  •   Clock Source (i.e. for sleep mode Bluetooth LE)

  •   Automotive grade devices are ideal for:

  •   Emergency Call Units, Remote Keyless Entry systems.
