HW-111 Real Time Clock I2C Module With Battery

The HW-111 real-time clock (RTC) IC has an I2C interface and has 8 pins. The HW-111 (DS1307) is a low-power clock/calendar with a battery backup SRAM of 56 bytes. The clock/calendar displays qualified data in seconds, minutes, hours, days, dates, months, and years. Each month's end date is automatically adjusted, especially for months with fewer than 31 days. Features:

• DS1307-based RTC Module.
• 1Hz output pin.
• Consumes less than 500nA in battery backup mode with oscillator running
• Underwriters Laboratory (UL) recognized
• Real-time clock (RTC) counts seconds, minutes, hours, dates of the month, month, day of the week, and year with leap-year compensation valid up to 2100
• 56-byte non-volatile RAM for data storage
• 56 Bytes of Non-volatile memory available to the user.
• The DS1307 is accessed via the I2C protocol.
• The module comes fully assembled and pre-programmed with the current time.
