PCF85263AT/AJ Description

Short technical summary and product information.

The NXP Semiconductors PCF85263AT/AJ is a CMOS Real-Time Clock (RTC) and calendar optimized for low power consumption. It operates over a voltage range of 0.9 V to 5.5 V and features an I2C-bus interface. This device provides year, month, day, weekday, hours, minutes, seconds, and 100th seconds based on a 32.768 kHz quartz crystal.

 

Key features include two independent alarms, a battery back-up circuit, and a watchdog timer. It also supports a stop-watch mode for elapsed time counting, from 100th seconds to 999,999 hours. The PCF85263AT/AJ includes two independent interrupt generators and programmable clock output for peripheral devices.

 

This component is available in an 8-SOIC package and is suitable for surface mounting. It operates within a temperature range of -40°C to 85°C. Applications include printers, copiers, electronic metering, digital cameras, and white goods.

 

The device offers a low current consumption, typically 0.28 μA at VDD = 3.0 V and Tamb = 25 °C. The I2C-bus interface operates at 400 kHz. The PCF85263AT/AJ is designed for battery-backed systems and mobile equipment requiring accurate timekeeping.
