For cost-sensitive,high-volume applications that require an ultra-miniatureReal Time Clock, Micro Crystal is introducing the world smallest integrated Real Time Clock Module RV-4162-C7. It is ideal for compact battery-powered devices,where its wide 1.3 to 4.4V operating range provides added flexibility. Timekeeping will function down to 1.0V witha current consumption of only 270nA typical. Communications with othercircuitry is simplified by an I2C Bus.
The 8 pin ceramic packagecontains a 32.768 kHz crystal,matched with a CMOS-based oscillator and real-time-clock circuitry. At room temperature, frequency and time keeping is within +/-20ppm withan operating temperature range of – 40 to +85°C. Aging rate is a maximum of +3ppmfor the first year.
The clock functiontracks tenths/hundredths of seconds, seconds, minutes and hours. The calendarfunction tracks date, month, year and century, with automatic leap yearcompensation. Programmable clock-out frequencies, alarm settings and a watchdogfunction increase flexibility using this device.
Because it is entirely self-contained, theRV-4162-C7 is a simple solution that can save engineering, procurement andinventory costs. External dimensions of the standard ceramic package are extremelysmall with 3.2x1.5x0.8mm which represents a board space of only 4.8mm2.Like all Micro Crystal products, it is RoHS compliant and 100% lead free.
Potential applications are widespread,including: battery powered handhelddevices, portable point of sales terminals, GPS, digital still cameras, glucosemeters, security systems, appliances, factory automation and programmable logiccontrol and data loggers.
The new Real Time Clock is available in production quantities inQ1/2011. Datasheets are available online. For more information, visit: http://www.microcrystal.com/ emailmailto:sales@microcrystal.comvv
