The OM13513 is the ideal evaluation and demo board to be used during the design phase of any project; only power and a serial bus (SPI-bus or I²C-bus) need to be connected. The OM13518 (USB to I²C-bus dongle) could be used for the I²C-bus connection.
The accurate RTCs PCF2127T and PCF2129AT are mounted together with a back-up lithium battery on a small PC-board. Two push buttons allow initiating time stamps. All signals are accessible on the pin connectors, overcoming the need to build a test PC-board before the circuit can be evaluated or the functionality can be tested together with the final application.
The board is helpful to evaluate the functionality of PCF2127T, PCF2129AT and PCA2129T/Q900 (the automotive grade version).
