SiTime MEMS Oscillators Integrated into Square Point-of-Sale Products

Square, a leading company processing credit card payments is using SiTime (SiT8008) low-power, programmable MEMS oscillator in the Square Terminal and Square Register point-of-sale (POS) products. The SiT8008 is one of SiTime’s most popular oscillators and is used in over 50 applications across the enterprise, industrial, mobile, and consumer markets.


The stability of the timing subsystem plays a critical role in ensuring the accuracy of POS products. System vendors do have a choice for timing. They can use an SiTime oscillator, which is an external, standalone timing device, or they can use an on-chip oscillator on their microprocessor/SoC. An external oscillator like the SiT8008 will consistently deliver 10-100 times better clock stability because of superior MEMS and analog technology and SiTime’s systems expertise. Additionally, the programmable architecture of the SiT8008 provides excellent configurability to the user and ensures fast delivery.

“Our goal is to provide sellers with POS solutions that operate with exceptional reliability and accuracy at all times,” said Thomas Templeton, General Manager for Hardware at Square. “SiTime’s timing solutions are a good match for our Square Terminal and Register products because they help us to deliver an accurate, reliable product to our customers.”
