PCA21125T SPI-bus Real-Time Clock and calendar
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.
AEC Q100 compliant for automotive applications
