DS12C887 Real Time Clock RTC IC

DS12C887 Real Time Clock RTC ICThe DS12C887 is a fully integrated real-time clock (RTC) module that provides time-of-day clock, calendar, and alarm functions with non-volatile battery-backed operation. It is a drop-in replacement for the popular DS12887, commonly used in PC motherboards and industrial embedded systems.This device integrates the RTC controller, quartz crystal, lithium battery, and CMOS RAM into a single 24-pin module, eliminating the need for external components. It maintains accurate timekeeping of seconds, minutes, hours, day, date, month, and year, including automatic leap-year compensation. Even when system power is off, the internal battery keeps the clock and memory running for many years.Click here to view related productsApplicationsPC motherboards and BIOS clock modulesIndustrial controllers and embedded systemsData logging and time-stamping equipmentNetworking and telecom equipmentTest and measurement instrumentsLegacy systems requiring DS12887-compatible RTCFeaturesType: Real-Time Clock (RTC) with integrated battery and crystalDrop-in replacement for DS12887 / DS12C887 familyIntegrated lithium battery, quartz crystal, and RTC controllerTimekeeping: Seconds, minutes, hours, day, date, month, yearAutomatic leap-year compensation114 bytes of battery-backed CMOS RAMAlarm and periodic interrupt functionsSquare-wave output availableParallel bus interfaceLong battery life (typically 10 years)No external crystal or battery requiredPackage: 24-pin DIP moduleHigh reliability and easy to useDS12C887-IC Datasheet*Product image for illustration purposes only, actual product may vary.
