PCF2123TS/1,118 Description

Short technical summary and product information.

The PCF2123TS/1,118 from NXP Semiconductors is a CMOS Real-Time Clock (RTC) and calendar designed for low-power applications. It features a serial peripheral interface (SPI-bus) for data transfer, supporting a maximum data rate of 6.25 Mbit/s. This device provides timekeeping from seconds to years, including year, month, day, weekday, hours, minutes, and seconds, based on a 32.768 kHz quartz crystal.

 

Key features include a low backup current of typically 100 nA at 2.0 V, a watchdog functionality, and freely programmable timer and alarm functions with interrupt capability. The operating voltage range is from 1.1 V to 5.5 V. The PCF2123TS/1,118 is supplied in a 14-TSSOP package suitable for surface mounting.

 

Applications for this RTC include timekeeping in battery-powered devices, metering, high-duration timers, and low standby power systems. It also offers a programmable offset register for frequency adjustment and integrated oscillator load capacitors.
