General Interest Hot Products title $16.90 title $1.96 title $1.59 title $1.75 title $3.20 title $5.35 title $7.90 DS3231 AT24C32 High Precision Clock Module DS3231 Chip 3.3--5.5V Precise DS3231 AT24C32 High Precision Clock Module DS3231 Chip 3.3--5.5V Precise 1.Feature The 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. The 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 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. Except for the high precision, this module also has some other functions which extend the additional function and the select range of the system host. It has a inside high precision digital temperature sensor module, the temperature accuracy of this sensor module is ±3°C. The on board control circuit can realize automatically power detection and manage the switch of the main power and the spare power. If the main power is cut off, this module can still provide precision data and temperature. When the power is back to normal, the on board reset function can restart the microcontroller 2.Interfaces: Size: 38mm(L)*22mm(W)*14mm(H) Working voltage: 3.3--5.5V Chip: High precision clock chip DS3231 Accuracy: ±2ppm from 0°C to +40°C Two Time-of-Day Alarms Programmable Square-Wave Output Real-Time Clock Counts Seconds, Minutes,Hours, Day, Date, Month, and Year with Leap Year Compensation Valid Up to 2100 Digital Temp Sensor Output: ±3°C Accuracy Storage chip: AT24C32( 32K) ICC Bus interface: Max transmission data: 400KHz( when the working voltage is 5V) Cascade with our ICC equipment Equips with battery holder so this module can work normally after there is power outage SHIPPING PAYMENT RETURNS FEEDBACK ABOUT US 1)All items will be shipped to your paypal address .Please update your latest address when you check out,and please make sure to provide us with correct,precise and detailed shipping address. 2)Most of the items will be shipped via Hongkong Airmail/Singapore Airmail .To US customers,we will send the package via E-packet . 3)All items will be shipped in 1-2 business days (excluding Sat,Sun & Holiday) after payment received and cleared.
