OM13510
PCF85263A I²C-bus evaluation board

The OM13510 is the ideal evaluation and demo board of the PCF85263A. It can be used in the design phase of any project. Just the supplies and the bus must be connected.

On the OM13510 the IC RTC PCF85263ATL is mounted together with a quartz crystal, a lithium battery plus the blocking capacitor, buffering the supply voltage. A push button allows activating the time stamp. All signals are accessible on a line of pins, overcoming the difficulties to contact the tiny package directly.
