GENERAL DESCRIPTION
1.1.
The RV-8063-C7 is a CMOS
real-time clock/calendar module optimized for low power consumption. An Offset
register allows to compensating the frequency deviation of the 32.768 kHz clock. All addresses and data are
transferred serially via a Serial Peripheral Interface (SPI-bus) with a maximum data rate of 7 Mbit/s. The register
address is incremented automatically after each written or read data byte.
This ultra small RTC module has been specially designed for miniature and cost sensitive high volume
applications.
