This module is based on the Maxim high accuracy RTC real time clock controller, Using an internal temperature compensation crystal oscillator, this RTC IC is able to provide extremely high accurate time keeping. The module includes an on-board battery backup and maintains accurate timekeeping when main power to the device is interrupted.
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. A 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.
Included on this module is an Atmel 24C32 32K (4096 x 8) serial I2C EEPROM which allows the module to be used as a simple data logger storing up to 4K of 8 bit data.
