PCA21125 Demo Board

OM13517UL Active

The OM13517UL is the demo board for PCA21125. The PCA21125 is a CMOS¹ Real-Time Clock (RTC) and calendar optimized for low-power consumption and an operating temperature up to 125 °C. Data is transferred via a Serial Peripheral Interface (SPI-bus) with a maximum data rate of 6.0 Mbit/s. Alarm and timer functions are also available with the possibility to generate a wake-up signal on the interrupt pin.
