The PCA21125 is a CMOS Real-Time Clock (RTC) and calendar optimized for low-powerconsumption and an operating temperature up to 125 °C. Data is transferred via a SerialPeripheral Interface (SPI-bus) with a maximum data rate of 6.0 Mbit/s. Alarm and timerfunctions are also available with the possibility to generate a wake-up signal on theinterrupt pin.\n
