Product Description

DS1340Z-33+T&R Real Time Clock I C RTC with Trickle Charger DRV5032FBDBZR DRV8601ZQVR DS0321SR25MHZ DS1302S+ DS1302SN DS1340 I2 C RTC with Trickle Charger


General Description
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 on the V BACKUP pin, a lower timekeeping voltage, and 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- ally through an I2C bidirectional bus.
