3. Applications

4. Ordering information

The PCA2125 is a CMOS real-time clock/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. An alarm and timer function

are also available with the possibility to generate a wake-up signal on an interrupt pin.

AEC Q100 qualiﬁed for automotive applications.
