The PCF8563T from NA is a CMOS real-time clock/calendar designed for low power consumption. It provides essential timekeeping functions including year, month, day, weekday, hours, minutes, and seconds, based on a 32.768 kHz quartz crystal.
This device operates within a wide supply voltage range of 1.0 V to 5.5 V. It features a 400 kHz two-wire I2C-bus interface for efficient data transfer. The PCF8563T also includes a programmable clock output with frequencies of 32.768 kHz, 1024 Hz, 32 Hz, and 1 Hz, making it suitable for various peripheral timing needs.
Additional features include alarm and timer functions, a voltage-low detector, and an integrated oscillator capacitor. The PCF8563T is available in an SO8 package, suitable for surface mount applications.
Key applications for the PCF8563T include mobile telephones, portable instruments, fax machines, and other battery-powered products where accurate timekeeping and low power are critical.
The supply voltage range is 1.0V to 5.5V when the I2C bus is inactive at 25°C, and 1.8V to 5.5V when the bus is active at 400 kHz over the full temperature range.
The operating ambient temperature range is -40°C to +85°C.
The maximum I2C-bus speed is 400 kbits/s.
The programmable clock output can provide 32.768 kHz, 1024 Hz, 32 Hz, or 1 Hz.
The PCF8563T is available in an SO8 surface mount package.
The maximum supply current is 800 μA when the I2C bus is active at 400 kHz with timer and CLKOUT disabled.
