PCF8523TS/1,112 Description

Short technical summary and product information.

The PCF8523TS/1,112 from NXP Semiconductors is a CMOS Real-Time Clock (RTC) and calendar designed for applications requiring low power consumption. It provides accurate timekeeping from seconds to years, based on a 32.768 kHz quartz crystal. The device supports an I2C interface with a maximum data rate of 1000 kbit/s.

 

Key features include alarm and timer functions with interrupt capability, a backup battery switch-over circuit for power failure detection, and selectable integrated oscillator load capacitors. The operating voltage range is from 1.0 V to 5.5 V, with a typical backup current of 150 nA at 3.0 V. An offset register allows for fine-tuning of the clock frequency.

 

This RTC is suitable for time-keeping applications in battery-powered devices and metering systems. It is supplied in a 14-TSSOP package for surface mounting. The operating temperature range is -40°C to 85°C.
