SiTime offer µPower MEMS oscillator family for wearables, IoT and mobile



SiT8021 µPower MEMS Oscillator

SiTime, a MEMS and analog semiconductor company and a wholly owned subsidiary of MegaChips, announced a new family of µPower MEMS Oscillators for the wearable, IoT and mobile markets. The SiT8021 oscillator, the first device in this family, shatters the limitations of quartz technology by setting new benchmarks in power, size and weight. The SiT8021 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.


“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 longer battery life.”


“Wearables and IoT are generating a lot of excitement as they are expected to drive the future growth of the semiconductor industry,” said Tony Massimini, Chief of Technology at Semico Research. “SiTime, with its leadership in Silicon MEMS timing solutions, is in a unique position to capitalize on the rapid growth of wearables and IoT.”
