Epson introduces the RX8804 real time clock module (RTC). Using digital temperature compensated oscillator (DTCXO) technology, the RX8804 achieves ±3.4 ppm or ±8 ppm accuracy over a range of -40°C to +85°C or -40°C to +105°C respectively. The RX8804 has very low power: 0.35 µA typical, available in a 3.2 mm x 2.5 mm x 1.0 mm ceramic package, includes a built-in crystal, and is surface-mountable.
