EPSON RTC: The Trusted Choice for Timing Device

Introduction

Epson — Leader of quartz technology over half a century. Since developing the world’s first quartz wristwatch in 1969, Epson (Seiko Epson Corp.) has continuously led the evolution of quartz crystal technology. As one of the world’s largest quartz crystal supplier, Epson has embedded the philosophy of “high efficiency, compactness, and precision” into every product. ARGO, as Epson’s trusted partner, is dedicated to bringing this Japanese precision and reliability into your product designs.

What is RTC (Real-Time Clock)? Why is Epson Different?

A Real-Time Clock (RTC) module is the core component that ensures uninterrupted timekeeping of system. Epson’s RTC modules stand out because of their unique modular design: integrating Epson’s high-quality 32.768kHz quartz crystal unit, optimized oscillation circuit, and RTC IC into a single package. This design eliminates the need for external component matching and guarantees maximum stability with reliability of the oscillation circuit, especially under harsh conditions such as extreme temperatures or humidity. 

Core Advantages of Epson RTC

• Industry-leading of ultra-low power consumption: Epson’s proprietary low-leakage CMOS IC process enables RTCs to operate with extremely low power even when the main system is in sleep mode. This is the key to extending battery life. (Example: RX8111CE, operating current only 0.1 μA)
• Extraordinary precision with temperature compensation: Using advanced photolithography technology to manufacture miniature quartz chips, Epson crystals deliver outstanding frequency and temperature characteristics. For applications requiring extreme accuracy, Epson offers models with built-in digital temperature compensation (DTCXO). (Example: RA8804CE, automotive-grade model achieves ±3.4ppm accuracy across -40℃ to +85℃, in other words, a monthly error of only about 9 seconds).
• High reliability and simplified design process: Every Epson’s RTC module is individually calibrated and tested before shipment to ensure guaranteed timekeeping accuracy. This eliminates the need for customers to perform precision adjustments on production lines, greatly simplifying design and manufacturing processes while improving final product quality. (Multiple models comply with AEC-Q100 automotive standards, proving reliability under demanding conditions.)

Conclusion

Choosing Epson = Choosing peace of mind. Epson’s RTC modules represent the pinnacle of quartz timekeeping craftsmanship and reliability. Whether your application is consumer electronics, demanding industrial control, or automotive systems, Epson provides the most stable and precise timekeeping core.
