SiTime Enters Wearables, IoT Markets with 32 kHz MEMS

SUNNYVALE, Calif. – June 4, 2014 – SiTime Corporation, an analog semiconductor company, today introduced the smallest, lowest power 32 kHz TCXO (temperature compensated oscillator). With its tiny footprint and ultra-low power consumption, the SiT1552 MEMS TCXO enables a paradigm shift in the size and battery life of wearable electronics and Internet of Things (IoT); such benefits are not available from legacy quartz devices.

“The markets for wearables and Internet of Things (IoT) are growing at a rapid pace. With this growth comes a need for customized devices that enable new features and higher performance,” said Marwan Boustany, Senior Analyst for MEMS & Sensors at IHS. “SiTime is a market share leader in the MEMS timing market and these advanced, 32 kHz MEMS TCXOs further support their market position.”

“By using its game-changing TempFlat MEMSTM and analog technology, SiTime has once again shattered the limitations of quartz. The SiT1552 MEMS TCXO is 20% of the size and consumes 50% of the power of comparable quartz devices,” said Piyush Sevalia, executive vice president of marketing at SiTime. “Our MEMS enable new system architectures that offer higher performance, small size and longer battery life. With another industry first, we continue to revolutionize the timing industry with our breakthrough MEMS solutions.”

The SiT1552 is the smallest TCXO available today and is available in a 1.5 x 0.8 mm chip scale package (CSP). The SiT1552 MEMS TCXO can perform various functions in a system such as:

  • Reference for real time clock (RTC) function
  • Sleep clock for connectivity – Bluetooth, Bluetooth Low Energy, WiFi
  • Heartbeat clock for battery supervisory function

Compared to a quartz TCXO, the SiT1552 MEMS TCXO is:

  • 20% of the size and is available in a 1.5 x 0.8mm CSP
  • 50% lower power, typically consuming less than 1 micro-amp
  • 45% thinner, with a height of 0.55 mm
  • 10 times faster startup, with a startup time of 0.3 milliseconds
  • 30 times higher shock resistance
  • 15 times higher reliability, at 500 million hours MTBF

Additional features of the SiT1552 include:

  • ±5 PPM frequency stability that enables 2 to 3 times longer battery life compared to a 180 PPM quartz resonator
  • NanoDriveTM, a programmable, low swing output that minimizes power and directly interfaces to the oscillator / RTC circuit in the downstream processor or PMIC
  • 1.5 to 3.63V operation, making it ideal for products that use a coin-cell or super-cap battery backup

Devices in the 1508 CSP are available in production now. Pricing is available upon request.

UWB: Because Location Matters

Sponsored by Mouser Electronics and Qorvo

While technologies like GPS, WiFi, and Bluetooth all offer various types of location services, none of them are well-suited to providing accurate, indoor/outdoor, low-power, real-time, 3D location data for edge and endpoint devices. In this episode of Chalk Talk, Amelia Dalton chats with Mickael Viot from Qorvo about ultra-wideband (UWB) technology, and how it can revolutionize a wide range of applications.
