I C RTC with Trickle Charger

General Description

Features

♦ Enhanced Second Source for the ST M41T00

The DS1340 is a real-time clock (RTC)/calendar that is

pin compatible and functionally equivalent to the ST

M41T00, including the software clock calibration. The

device additionally provides trickle-charge capability

♦ Available in a Surface-Mount Package with an

Integrated Crystal (DS1340C)

♦ Fast (400kHz) I C Interface

on the V

pin, a lower timekeeping voltage, and

BACKUP

♦ Software Clock Calibration

an oscillator STOP flag. Block access of the register

map is identical to the ST device. Two additional regis-

ters, which are accessed individually, are required for

the trickle charger and flag. The clock/calendar pro-

vides seconds, minutes, hours, day, date, month, and

year information. A built-in power-sense circuit detects

power failures and automatically switches to the back-

up supply. Reads and writes are inhibited while the

clock continues to run. The device is programmed seri-

♦ RTC Counts Seconds, Minutes, Hours, Day, Date,

Month, and Year

♦ Automatic Power-Fail Detect and Switch Circuitry

♦ Trickle-Charge Capability

♦ Low Timekeeping Voltage Down to 1.3V

♦ Three Operating Voltage Ranges (1.8V, 3V, and 3.3V)

♦ Oscillator Stop Flag

ally through an I C^*bidirectional bus.

♦ Available in 8-Pin µSOP or SO Packages

♦ Underwriters Laboratory (UL) Recognized
