EPSON RX8901CE, new generation RTC module for smart electricity meter system

Epson recently launched a new generation of RTC module products specifically for smart electricity meter systems, RX8901CE.

The product is capable of operating accurately in a wide temperature range, even in harsh weather conditions.
