The NXP PCF8523 and PCF2123 are CMOS devices that

combine a real-time clock (RTC) and a calendar. Optimized for

low power consumption, they operate at a current of less than

100 nA with a 2.0 V power supply, and consume less than 0.2 μW

of power. The PCF8523 uses an I

PCF2123 is equipped with an SPI serial interface.

Both devices are cased in tiny leadless packages that save

space in compact designs. This makes them well suited for

handheld and battery-operated applications, including blood-

pressure monitors and other home-use medical devices, pocket

calculators, portable phones, and PDAs. They are also an

excellent choice for white goods, such as washing machines,

metering units, and other industrial systems. Both devices can

be powered by a very small battery cell or a super-cap.
