PCA2125
Datasheet
General description
The PCA2125 is a CMOS real-time clock/calendar optimized for low-power consumption and an operating temperature up to 125 Cel. 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.
Features
- Provides year, month, day, weekday, hours, minutes and seconds based on 32.768 kHz quartz crystal
- Resolution: seconds to years
- Clock operating voltage: 1.3 V to 5.5 V
- Low backup current: typical 0.55 uA at VDD = 3.0 V and Tamb = 25 Cel
- 3-line SPI-bus with separate combinable data input and output
- Serial interface (at VDD = 1.6 V to 5.5 V)
- 1 second or 1 minute interrupt output
- Freely programmable timer with interrupt capability
- Freely programmable alarm function with interrupt capability
- Integrated oscillator capacitor
- Internal power-on reset
