DESCRIPTION (continued) The powerful Dual Alarms can be set to any Clock/Calendar value for a match. For instance, every minute, every Tuesday March 21. The alarms can be polled in the Status Register or provide a ...

... For example, a >20ppm frequency deviation translates into an accuracy of >1 minute per month. These parameters are available from the crystal manufacturer. Intersil’s RTC family provides on-chip crystal compensation networks to adjust load- capacitance to tune oscillator frequency from +116 ppm to -37 ppm when using a 12.5 pF load crystal. For more detail information see the Application section ...

When there is a match, an alarm flag is set. The occur- rence of an alarm can be determined by polling the AL0 and AL1 bits or by enabling the IRQ output, using it as hardware flag. The alarm enable ...

... In addition to the analog compensation afforded by the adjustable load capacitance, a digital compensation feature is available for the Intersil RTC family. There are three bits known as the Digital Trimming Register or DTR, and they operate by adding or skipping pulses in the clock signal. The range provided is ±30ppm in increments of 10ppm ...

... Backup Battery Operation Many types of batteries can be used with the Intersil RTC products. 3.0V or 3.6V Lithium batteries are appropriate, and sizes are available that can power a Intersil RTC device for years. Another option is to use a supercapacitor for applications where Vcc may disappear intermittently for short periods of time ...
Page 19
Depending on the value of supercapacitor used, backup time can last from a few days to two weeks (with >1F). A simple silicon or Schottky barrier diode can be used in series with Vcc to charge the supercapacitor, which is ...
