NXP ultra-low-power

RTC/calendars PCF8523

& PCF2123

Save power with small,

ultra-efﬁcient RTCs

Designed to perform critical time-keeping functions in a range of applications, these small, highly

efﬁcient RTC/calendars ﬁt nearly anywhere and cut power demands by as much as 60 percent.

Key features

Key applications

} 32.768 kHz quartz crystal

} Resolution: seconds to years

} Time-keeping functions

} Battery-powered devices

} Freely programmable timer and alarm function with interrupt } Metering

} Low backup current: 100 nA typ at V_DD= 2.0 V

and Tamb = 25 °C

} High-duration timers

} Daily alarms

} Internal Power-On Reset

} Systems with low standby power

} Open drain interrupt and clock output pins

} Programmable offset register for frequency adjustment

} Watchdog timer

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 0.2μW

of power. The PCF8523 uses an I²C-bus serial interface while the

PCF2123 is equipped with an SPI serial interface.

Ultra-low-power I²C RTC/calendar PCF8523

} Clock operating voltage: 1.2 V to 5.5 V

} 2 line bi-directional 1 MHz Fast-mode Plus I²C interface

} Battery backup input pin and switch-over circuitry

} Integrated oscillator load capacitors for C_L= 7 and 12.5 pF

} Second countdown timer with interrupt output

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

Ultra-low-power SPI RTC/calendar PCF2123

} Clock operating voltage: 1.1 to 5.5 V

} 3-line SPI with separate, combinable data I/O

} Serial interface (at V_DD= 1.6 to 5.5 V)

} Free programmable timer and alarm with interrupt capability be powered by a very small battery cell or a super-cap.

} Integrated oscillator load capacitors for C_L= 7 pF
