Overview

R2023K/T 2-wire Serial Interface Real Time Clock IC www.DataSheet4U.com NO.EA-124-070221 OUTLINE The R2023K/T is a CMOS real-time clock IC connected to the CPU by two signal lines, SCL, SDA, and configured to perform serial transmission of time and calendar data to the CPU.

The periodic interrupt circuit is configured to generate interrupt signals with six selectable interrupts ranging from 0.5 seconds to 1 month.

The 2 alarm interrupt circuits generate interrupt signals at preset times.

Key Features

Minimum Timekeeping supply voltage TYP:0.66 to 5.5v (Worst: 1.00V to 5.5v); VDD pin Low power consumption 0.45µA TYP at VDD=3V (1.00µA MAX. ) Two signal lines (SCL, SDA) required for connection to the CPU. Time counters (counting hours, minutes, and seconds) and calendar counters (counting years, months, days, and weeks) (in BCD format) Interrupt ci.
