Demoboard for the SPI-bus RTC PCF2123

The OM13512 is the ideal evaluation/demo board to use during the design phase of any project; only the power supply and the SPI-bus must be connected. On the OM13512 the RTC PCF2123TS with SPI-bus is mounted together with a quartz crystal, a coin cell 1.5 V battery and the decoupling capacitor to buffer the supply voltage.

All signals are accessible on a row of pins, overcoming the need to build a test PC-board before the circuit can be evaluated or the functionality being tested together with the final application.
