esigned for precision time keeping, Epson’s RA8900 Automotive DTCXO Real-Time Clock (RTC) uses Digitally Temperature-Compensated Crystal Oscillator (DTCXO) technology to achieve ±3.4 ppm at the temperature range of -40 to +85 °C (9 s/mo.).
Despite the high accuracy, Epson’s RA8900 includes an integrated crystal and features low power of 0.7 μA (typ) backup current.
The high accuracy is essential for precise time keeping, as required by car clocks, infotainment, battery management, and other automotive applications.
To keep the time counter running even at main power failure, Epson’s RA8900 supply voltage of 2.5-5.5 V 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.
Epson’s RA8900 is offered in a small package of 3.2 x 2.5 x 1.0 mm3 and is manufactured on a dedicated automotive line and meets all applicable automotive quality standards, including AEC-Q200 grade 3, ISO9001, and TS16949.
Features
Epson is a global technology leader dedicated to connecting people, things and information with its original efficient, compact and precision technologies. With a lineup that ranges from inkjet printers and digital printing systems to 3LCD projectors, watches and industrial robots, the company is focused on driving innovations and exceeding customer expectations in inkjet, visual communications, wearables and robotics.
