The DS1371 is a 32-bit binary counter that is designed to continuously count time in seconds. An additional counter that can generate a periodic alarm or serve as a watchdog timer is also provided. If enabled as a watchdog timer, the watchdog strobe input pin provides a hardware reset of the counter. If disabled, this counter can be used as 3 Bytes of general-purpose RAM. A configurable output can be used as an interrupt or provide a square wave at one of four selectable frequencies. The device is programmed serially through a I²C bidirectional bus.ApplicationsElapsed Time MeasurementsPoint-of-Sale EquipmentPortable InstrumentationServers

The DS1501/DS1511 are full-function, year 2000-compliant real-time clock/calendars (RTCs) with an RTC alarm, watchdog timer, power-on reset, battery monitors, 256 bytes NV SRAM, and a 32.768kHz output. User access to all registers within the DS1501/DS1511 is accomplished with a byte-wide interface, as shown in Figure 8. The RTC registers contain century, year, month, date, day, hours, minutes, and seconds data in 24-hour binary-coded decimal (BCD) format. Corrections for day of month and leap year are made automatically.ApplicationsBattery-Backed SystemsConsumer ElectronicsOffice EquipmentRemote SystemsTelecom Switches

The DS1023 is an 8-bit programmable delay line similar in function to the DS1020/DS1021.Additional features have been added to extend the range of applications:The internal delay line architecture has been revised to allow clock signals to be delayed by up to a fullperiod or more. Combined with an on-chip reference delay (to offset the inherent or 'step zero' delay ofthe device) clock phase can now be varied over the full 0-360 degree range.On-chip gating is provided to allow the device to provide a pulse width modulated output, triggered bythe input with duration set by the programmed value.Alternatively the output signal may be inverted on chip, allowing the device to perform as a free-runningoscillator if the output is (externally) connected to the input.
