![]() ![]() As such, the DS12887 is a complete subsystem replacing 16 components in a typical application. ![]() A lithium energy source, quartz crystal, and write– protection circuitry are contained within a 24–pin dual in-line package. Access to this additional RAM space is determined by the logic level presented on AD6 during the address portion of an access cycle. The DS12887 is identical in form, fit, and function to the DS1287, and has an additional 64 bytes of general purpose RAM.

Wir haften nicht für Verluste oder Schäden, die durch die oben genannten Informationen verursacht werden.The DS12887 Real Time Clock plus RAM is designed to be a direct replacement for the DS1287. *Diese Informationen dienen nur zu allgemeinen Informationszwecken. ![]() ![]() Along with the real time clock this chip also holds the CMOS battery, all entombed together in a compact plugin unit. Mit dem Fokus auf Energieeffizienz und Nachhaltigkeit stehen die integrierten Maxim-Produkte an der Spitze der Halbleiterindustrie und treiben technologische Fortschritte in den Bereichen analoge und gemischte ICS vor. Some older PC-type computers used the (in)famous DS1287 Dallas Real Time Clock chip (photo 1) to supply CMOS power. Maxim integrierte Produkte widmet sich der Innovation und Kundenzufriedenheit und setzt sich für eine qualitativ hochwertige, zuverlässige Lösungen für seine Kunden ein. Maxim integrierte Produkte bedienen Kunden in einer Vielzahl von Märkten, einschließlich Kommunikation, Computer, Verbraucher, Industrie, Medizin und Automobil.ĭas Unternehmen bietet ein umfassendes Produktportfolio an, darunter Datenkonverter, Verstärker und Komparatoren, ICS, Microcontroller, Sicherheits- und Schutzgeräte sowie Sensoren. Maxim Integrated Products ist ein börsennotiertes Unternehmen, das eine breite Palette von analogen und gemischten Signal integrierten Schaltkreisen (ICs) entwirft, entwickelt und verkauft.ĭas Unternehmen wurde 1983 gegründet und hat seinen Hauptsitz in San Jose, Kalifornien. ♦ Underwriters Laboratory (UL) Recognized ♦ Optional Industrial Temperature Range Available Even its successor DS12887 is pretty hard to get and darn expensive. ♦ Optional Encapsulated DIP (EDIP) Package with Integrated Crystal and Battery (DS12887, DS12887A, DS12C887, DS12C887A) Well - these have the dreaded Dallas DS1287 all in one Real Time Clock (RTC) chip. ♦ Optional 28-Pin PLCC Surface Mount Package or 32-Pin TQFP (DS12885) ♦ Automatic Power-Fail Detect and Switch Circuitry ♦ Time-of-Day Alarm Once Per Second to Once Per Day ♦ Interrupt Output with Three Independently Maskable Interrupt Flags ♦ 114 Bytes of General-Purpose, Battery-Backed RAM (113 Bytes in the DS12C887 and DS12C887A) ♦ 14 Bytes of Clock and Control Registers ♦ Interfaced with Software as 128 RAM Locations ♦ Selectable Intel or Motorola Bus Timing Review Dallas Maxim's on-line application notes for features, installation and compatibility instructions prior to purchasing the DS12887 Real Time Clock. ♦ 12-Hour or 24-Hour Clock with AM and PM in 12-Hour Mode Replaces DS1287 and used in personal computers to keep time, date, and CMOS settings while PC power is off. ♦ RTC Counts Seconds, Minutes, Hours, Day, Date, Month, and Year with Leap Year Compensation Through 2099 ♦ Drop-In Replacement for IBM AT Computer Clock/Calendar The DS12887 integrates a quartz crystal and lithium energy source into a 24-pin encapsulated DIP package. The devices provide a real-time clock/calendar, one time-of-day alarm, three maskable interrupts with a common interrupt output, a programmable square wave, and 114 bytes of battery backed static RAM (113 bytes in the DS12C887 and DS12C887A). The DS12885, DS12887, and DS12C887 real-time clocks (RTCs) are designed to be direct replacements for the DS1285 and DS1287. ![]()
