Now in Mass production: RX8901CE & RX4901CE - compact Real-Time-Clock Modules for smarter devices

For industrial and IoT applications - precise timing, low power


► Zur deutschen Pressemitteilung

Munich, 1. July 2025 - The RX8901CE and RX4901CE, two new RTC (real-time clock) modules, are now available in mass production by Seiko Epson Corporation. These are Epson’s smallest RTC modules to date, measuring just 3.2 × 2.5 × 1.0 mm, and are designed for industrial and IoT applications requiring precise timekeeping, low power consumption, and compact form factors. The RX8901CE supports an I2C-Bus interface, while the RX4901CE offers an SPI-Bus interface, providing flexibility for a wide range of system designs.

With typical current consumption of only 0.24 µA—30% lower than previous models—these modules are ideal for battery-powered devices such as smart meters, security systems, and factory automation equipment. They offer expanded time stamp memory (up to 32 records) and are factory-calibrated for high accuracy, eliminating the need for post-installation adjustment. Their stability across wide temperature ranges makes them especially suited for outdoor and automotive environments. Epson continues to support sustainable innovation through its energy-efficient and precision technologies.

Product Applications:

The new RTC modules are well-suited for integration into smart meters, security systems, factory automation equipment, and a variety of compact electronic devices that require precise and reliable timekeeping.

Jetzt in Serienproduktion: RX8901CE & RX4901CE – kompakte Echtzeituhr-Module für intelligentere Geräte

Für Industrie- und IoT-Anwendungen – präzise Zeitmessung, geringer Stromverbrauch

München, 1. Juli 2025 - Die RX8901CE und RX4901CE, zwei neue RTC-Module (Real-Time Clock), sind jetzt in Serienproduktion bei der Seiko Epson Corporation verfügbar. Mit Abmessungen von nur 3,2 × 2,5 × 1,0 mm zählen sie zu den kleinsten RTC-Modulen von Epson und wurden speziell für industrielle und IoT-Anwendungen entwickelt, die präzise Zeitmessung, geringen Stromverbrauch und kompakte Bauformen erfordern. Der RX8901CE unterstützt eine I2C-Bus-Schnittstelle, während der RX4901CE eine SPI-Bus-Schnittstelle bietet – für maximale Flexibilität bei der Systemintegration.

Mit einem typischen Stromverbrauch von nur 0,24 µA – 30 % weniger als bei früheren Modellen – eignen sich die Module ideal für batteriebetriebene Geräte wie Smart Meter, Sicherheitssysteme und Automatisierungstechnik. Sie verfügen über einen erweiterten Zeitstempel-Speicher (bis zu 32 Einträge) und werden werkseitig kalibriert, was eine nachträgliche Justierung überflüssig macht. Dank ihrer Stabilität über einen breiten Temperaturbereich sind sie besonders für den Einsatz im Außenbereich und in Fahrzeugen geeignet. Epson setzt weiterhin auf energieeffiziente Präzisionstechnologien zur Förderung nachhaltiger Innovationen.

Anwendungsbereiche:
Die neuen RTC-Module eignen sich hervorragend für den Einsatz in Smart Metern, Sicherheitssystemen, Automatisierungslösungen und einer Vielzahl kompakter elektronischer Geräte, die eine zuverlässige und präzise Zeitmessung benötigen.
