    DS1501WEN Product overview

    GENERAL DESCRIPTION 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. FEATURES BCD-Coded Century, Year, Month, Date, Day, Hours, Minutes, and Seconds with Automatic Leap-Year Compensation Valid Up to the Year 2100 Programmable Watchdog Timer and RTC Alarm Century Register; Y2K-Compliant RTC +3.3 (W) or +5V (Y) Operation Precision Power-On Reset Power-Control Circuitry Support System   Power-On from Date/Day/Time Alarm or Key   Closure/Modem-Detect Signal 256 Bytes Battery-Backed SRAM Auxiliary Battery Input Accuracy of DS1511 Better than ±1 Minute/Month at +25°C Day-of-Week/Date Alarm Register Crystal Select Bit Allow RTC to Operate with 6pF or 12.6pF Crystal (DS1501) Battery Voltage-Level Indicator Flags Available as Chip (DS1501) or Stand-Alone   Encapsulated DIP Module with Embedded   Battery and Crystal (DS1511) APPLICATIONS Remote Systems Battery-Backed Systems Telecom Switches Office Equipment Consumer Electronics Underwriters Laboratories (UL) Recognized

    DS1501WEN+ Product overview

    The DS1501WEN+ is a Y2K compliant watchdog real time clock (RTC) in 28 pin TSOP package. It is a low power clock/date device with a programmable day of week/date alarm and it has 3.3V operation. This full function, year 2000 compliant real time clock/calendar contains RTC alarm, watchdog timer, precision power-on reset, battery monitors, 256byte battery backed NV SRAM and 32.768KHz output. User access to all registers within the DS1501 is accomplished with bytewide interface. The RTC registers includes BCD coded century, year, month, date, day, hours, minutes and seconds with automatic leap year compensation valid up to the year 2100 (corrections for day of month and leap year are made automatically). Power control circuitry supports system power-on from date/day/time alarm or key closure/modem detect signal. The DS1501 is used in remote systems, battery backed systems, telecom switches and office equipments.
