OM13513, RTC 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
