{"product_id":"ds3231-ic-real-time-clock-integrated","title":"DS3231 IC Real Time Clock Integrated","description":"\u003cdiv\u003e\n\u003cdiv\u003e\n\u003cp\u003eThe DS3231 is a low-cost, extremely accurate I²C real-time clock (RTC) with an integrated temperature compensated crystal oscillator (TCXO) and crystal. The device incorporates a battery input and maintains accurate timekeeping when main power to the device is interrupted. The integration of the crystal resonator enhances the long-term accuracy of the device as well as reduces the piece-part count in a manufacturing line. The DS3231 is available in commercial and industrial temperature ranges and is offered in a 16-pin, 300-mil SO package.\u003c\/p\u003e\n\u003cp\u003eThe RTC maintains seconds, minutes, hours, day, date, month, and year information. The date at the end of the month is automatically adjusted for months with fewer than 31 days, including corrections for leap year. The clock operates in either the 24-hour or 12-hour format with an active-low AM\/PM indicator. Two programmable time-of-day alarms and a programmable square-wave output are provided. Address and data are transferred serially through an I²C bidirectional bus.\u003c\/p\u003e\n\u003cp\u003eA precision temperature-compensated voltage reference and comparator circuit monitors the status of VCC to detect power failures, to provide a reset output, and to automatically switch to the backup supply when necessary. Additionally, the active-low RST pin is monitored as a pushbutton input for generating a µP reset.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ch5\u003e\u003cstrong\u003eApplications\/Uses\u003c\/strong\u003e\u003c\/h5\u003e\n\u003col\u003e\n\u003cli\u003eGlobal Positioning Systems (GPS)\u003c\/li\u003e\n\u003cli\u003eServers\u003c\/li\u003e\n\u003cli\u003eTelematics\u003c\/li\u003e\n\u003cli\u003eUtility Power Meters\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cdiv class=\"row\"\u003e\n\u003cdiv\u003e\u003chr\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv class=\"col-sm-8\"\u003e\u003cstrong\u003e\u003ca\u003eDS3231: Block Diagram: \u003c\/a\u003e\u003c\/strong\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003ca href=\"https:\/\/robu.in\/wp-content\/uploads\/2019\/03\/w44t.jpg\"\u003e\u003cimg sizes=\"(max-width: 504px) 100vw, 504px\" srcset=\"https:\/\/robu.in\/wp-content\/uploads\/2019\/03\/w44t.jpg 650w, https:\/\/robu.in\/wp-content\/uploads\/2019\/03\/w44t-300x278.jpg 300w\" title=\"DS3231 IC Real Time Clock Integrated RTC\/TCXO\/Crystal,DS3231,Real Time Clock IC Generic\" height=\"468\" width=\"504\" alt=\"DS3231 IC Real Time Clock Integrated RTC\/TCXO\/Crystal,DS3231,Real Time Clock IC\" src=\"https:\/\/robu.in\/wp-content\/uploads\/2019\/03\/w44t.jpg\" class=\"wp-image-330417 aligncenter\" decoding=\"async\" loading=\"lazy\"\u003e\u003c\/a\u003e\u003c\/div\u003e\n\u003cdiv class=\"col-sm-4\"\u003e\u003chr\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"row\"\u003e\n\u003cdiv class=\"col-sm-8\"\u003e\n\u003ch4\u003eSpecifications and Features:\u003c\/h4\u003e\n\u003col\u003e\n\u003cli\u003eHighly Accurate RTC Completely Manages All Timekeeping Functions\n\u003cul\u003e\n\u003cli\u003eReal-Time Clock Counts Seconds, Minutes, Hours, Date of the Month, Month, Day of the Week, and Year, with Leap-Year Compensation Valid Up to 2100\u003c\/li\u003e\n\u003cli\u003eAccuracy ±2ppm from 0°C to +40°C\u003c\/li\u003e\n\u003cli\u003eAccuracy ±3.5ppm from -40°C to +85°C\u003c\/li\u003e\n\u003cli\u003eDigital Temp Sensor Output: ±3°C Accuracy\u003c\/li\u003e\n\u003cli\u003eRegister for Aging Trim\u003c\/li\u003e\n\u003cli\u003eActive-Low RST Output\/Pushbutton Reset Debounce Input\u003c\/li\u003e\n\u003cli\u003eTwo Time-of-Day Alarms\u003c\/li\u003e\n\u003cli\u003eProgrammable Square-Wave Output Signal\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eSimple Serial Interface Connects to Most Microcontrollers\n\u003cul\u003e\n\u003cli\u003eFast (400kHz) I\u003csup\u003e2\u003c\/sup\u003eC Interface\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eBattery-Backup Input for Continuous Timekeeping\n\u003cul\u003e\n\u003cli\u003eLow Power Operation Extends Battery-Backup Run Time\u003c\/li\u003e\n\u003cli\u003e3.3V Operation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eOperating Temperature Ranges: Commercial (0°C to +70°C) and Industrial (-40°C to +85°C)\u003c\/li\u003e\n\u003cli\u003eUnderwriters Laboratories\u003csup\u003e®\u003c\/sup\u003e (UL) Recognized\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003chr\u003e\n\u003ch4\u003e\u003cstrong\u003ePackage Includes:\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003e1 x DS3231 IC Real Time Clock Integrated RTC\/TCXO\/Crystal\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"VOLTROS","offers":[{"title":"Default Title","offer_id":51312273752360,"sku":"VT01640","price":170.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0947\/7908\/1000\/files\/V_12.png?v=1767419475","url":"https:\/\/voltros.in\/products\/ds3231-ic-real-time-clock-integrated","provider":"WHITEVALLEY TECHNOLOGIES PRIVATE LIMITED","version":"1.0","type":"link"}
