DS3231 DC5V 40mA 0.2W High Precision IIC RTC and TCXO Power-off Memory 0.8-Inch LED Electronic Clock

Product Introduction: The DS3231 is a low cost, high precision IIC Real Time Clock(RTC) with an Temperature Compensate X'tal (crystal) Oscillator(TCXO) and crystal. The device includes a battery input that maintains accurate timing when the mains supply is disconnected. The integrated crystal oscillator increases the long-term accuracy of the device and reduces the number of components in the production line. The DS3231 is available in commercial and industrial temperature ranges in a 16-pin, 300 mil SO package. The RTC maintains seconds, minutes, hours, weeks, dates, months, and years. For months less than 31 days, the month-end date will be automatically adjusted. The working format of the clock can be 24-hour or 12-hour format indicated by AM/PM. Two programmable calendar alarms and one programmable square wave output are provided. The address and data are transmitted serially via the IIC bidirectional bus. A precision, temperature-compensated voltage reference and comparator are used to monitor its status, detect power failures, and provide a reset output. And automatically switch 0 to the backup power source if necessary. Product Features: 1. 0.8-inch with a second four-point digital and time display is clear. 2. With power-off memory function, the chip will automatically go after power-off. No need to adjust after power-on and backup battery CR1220 has already equipped. 3. If a small current is used to turn off the mobile power, it will automatically go out. Product Parameters: Working voltage: DC 5V Working current: 40mA Working power: 0.2W Size: 72x26x13mm Color: Green, red, blue and white (Optional) Range of working temperature: Commercial grade: 0-70C Industrial grade: -40-85C Product Application Scenario: 1. Server 2. Electric Meter 3. Telematics System 4. GPS Instruction Manual: 1. Use the DC 5V mobile phone charger or mobile power. Use the Micro USB cable, and display the time when the power is turned on. 2. There are two buttons SET and ADD. The SET button is used to switch, and the ADD is used to accumulate. 3. After power-on, please press SET button, hour digit will flash, and press ADD button can adjust hours(24 hours). Press SET button again, minute digit will flash, and press ADD button can adjust minutes. Press SET button again, second digit will flash, and press ADD button can adjust the seconds to 0. Press SET button again, the adjustments will end. Package Included: 1 x Electronic Clock Module (without USB cable)
