Feature:
DS3231 is a low-cost, high-precision I2C real-time clock (RTC), with an integrated temperature-compensated crystal oscillator (TCXO) and crystal.
The device includes a battery input terminal, which can maintain accurate timing when the main power supply is disconnected.
The integrated crystal oscillator improves the long-term accuracy of the device and reduces the number of components in the production line. DS3231 offers commercial grade and industrial grade temperature range, adopts 16-pin 300mil SO package.
RTC saves seconds, minutes, hours, day of the week, date, month and year information. For months with less than 31 days, the date at the end of the month will be automatically adjusted, including corrections for leap years. And provide leap year compensation valid until 2100.
The working format of the clock can be 24-hour or 12-hour format with AM/PM indication. Provides two configurable calendar alarms and a configurable square wave output. Address and data are serially transmitted via I2C
