Epson’s RA8804 DTCXO RTC

Precise time keeping, higher accuracy over temperature and low power for automotive applications

Munich, September 6, 2018 – Epson Europe Electronics GmbH („Epson“) presents the RA8804 DTCXO RTC.
Designed for precision time keeping, Epson’s RA8804 Automotive DTCXO RTC uses Digitally Temperature-Compensated Crystal Oscillator (DTCXO) technology to achieve ±3.4 or ±8 ppm accuracy over temperature of -40 to +85 °C or -40 to +105 °C respectively, equivalent to 9 or 20 seconds per month. This high accuracy is essential for precise time keeping, as required by car clocks, infotainment, battery management, and other automotive applications.

RA8804CEEpson’s RA8804 includes a crystal, a digitally temperature-compensated crystal oscillator (DTCXO), and counters to keep track of time and date. Epson’s RA8804 also includes automatic battery backup and time-keeping functions such as alarms and timers. 

Epson’s RA8804 with a supply voltage of 1.6-5.5 V is low power (0.35 μA (typ) backup current), has a frequency output pin which can be programmed to 1 Hz, 1024 Hz, or 32.768 kHz and is offered in a small package (3.2 x 2.5 x 1.0 mm3).
Epson’s RA8804 is manufactured on a dedicated automotive line and meets the automotive quality standard AEC-Q100. PPAP data is available upon request.
