SiTime Brings New MEMS Oscillators to IoT

SiTime introduced a new family of µPower MEMS Oscillators for the timing requirements of the wearable, IoT and mobile markets.

The SiT8021 oscillator, the first device in this family, consumes 90% lower power, is 40% smaller, and 70% lighter than quartz devices. These best in class specifications enable the longest battery life as well as the smallest size and weight of smart watches, fitness bands, tablets, smart phones, portable audio and accessories.

Key specs:

  • 100 μA of supply current, 90% lower
  • Ultra-small 1.5 mm x 0.8 mm package, 40% smaller
  • Mass of 1.28 mg, 70% lighter
  • Height of 0.55 mm, 45% thinner
  • 1 to 26 MHz output frequency with 6 decimal places of accuracy
  • Operating temperature from -40°C to +85°C
  • ±100 PPM frequency stability
  • 1.8V operation for battery powered applications
  • Unique, programmable output drive strength for best EMI or driving multiple loads
  • 30 times higher reliability, at 1140 million hours MTBF (< 1 FIT)
  • 30 times higher shock & vibration resistance, the best in the industry


“In 2013 and 2014, SiTime introduced the smallest, lowest power 32 kHz oscillator and TCXO for the wearables, IoT and mobile markets. These products were based on SiTime’s game-changing TempFlat™ MEMS and low-power programmable analog technology. Customers adopted these 32 kHz XOs and TCXOs rapidly – we expect to ship several tens of millions of units in 2015,” said Piyush Sevalia, executive vice president of marketing at SiTime. “Innovating rapidly, SiTime used our revolutionary technologies to deliver the μPower family of MHz MEMS oscillators. This new family of oscillators breaks through the limitation of quartz technology and enables smaller electronic devices with dramatically longer battery life.”

Sampling is underway.
