Epson Europe Electronics GmbH presents the real-time clock module RX8900.<\/p>\n

Epson\u2019s RX8900 Real-Time Clock (RTC) with a supply voltage of 2.5-5.5 V is offered in a small sized package (3.2 x 2.5 x 1.0 mm3 or 10.1 x 7.4 x 3.3 mm3). The package includes an IC and crystal with a factory-calibrated Digitally Temperature-Compensated Crystal Oscillator (DTXO).<\/strong><\/p>\n

Due to the usage of DTCXO technology compensating not only the temperature dependency but as well the initial tolerance and circuit variations, a high accuracy of \u00b13.4 ppm over the industrial temperature range -40 to +85 \u00b0C (9 s\/mo.) can be achieved. This high accuracy is essential for precise time keeping, as required by eMeters, lighting, and other industrial or outdoor applications.<\/p>\n

To keep the time counter running even at main power failure, Epson\u2019s RX8900 can detect the loss of main power source and automatically switch to a backup supply from a battery or supercapacitor with a supply voltage of 1.6-5.5 V.<\/p>\n
