New real-time-clock modules with time stamp function

15/03/2024

The RA8000CE and RA4000CE, two new RTC modules with an integrated digital temperature-compensated crystal oscillator for in-vehicle applications, are now available in mass production.

Each has a time-stamp feature and is packaged in a small 3.2 x 2.5 x 1.0 mm package. The large-scale manufacturing has started and both parts are ready to be ordered now.

Epson's RTC modules are commonly utilized in devices that require the logging and storage of time-of-day data. Electronic devices have been integrating more and more in recent years, all the while reducing their environmental and physical footprints. RTC modules that can retain accurate time over a broader temperature range and use less current are becoming more and more necessary.

Ideal for wide range of products that need clock functions, from small electronics to factory automation equipment
