产品概述

The DS1500WE+ is a Y2K watchdog RTC with non-volatile control in 32 pin TSOP package. It is a full-function, year 2000-compliant real time clock/calendar (RTC) with an alarm, watchdog timer, power-on reset, battery monitors, 256 bytes of on-board non-volatile (NV) SRAM, NV control for backing up an external SRAM and a 32.768KHz output. User access to all registers within the DS1500 is accomplished with a byte-wide interface. 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 compensation valid up to the year 2100. Power control circuitry supports system power-on from date/day/time alarm or key closure. The DS1500 is used in remote systems, battery backed systems, telecom switches and office equipments.
