DS1340, DS1340C I²C实时时钟，带
ds1340, ds1340c i²c实时时钟，带有涓流充电器，可通过软件进行校准
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 vbackup pin, a lower timekeeping voltage, and an oscillator stop flag. block access of the register map is identical to the st device. two additional registers, which are accessed individually, are required for the trickle charger and flag. the clock/calendar provides seconds, minutes, hours, day, date, month, and year information. a built-in power-sense circuit detects power failures and automatically switches to the backup supply. the device is programmed serially through an i²c bidirectional bus.
关键特性
enhanced second source for the st m41t00 available in a surface-mount package with an integrated crystal (ds1340c) fast (400khz) i²c interface software clock calibration 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 available in 8-pin µsop or so packages underwriters laboratories (ul) recognized 应用/使用
