Real Time Clock with NV Memory, Integrated

A range of real-time clock products from Maxim incorporating non-volatile RAM memory for data retention. The clock/calendar functions provide seconds, minutes, hours, day, date, month, and year information. The clocks generally operate in either the 12 or 24-hour format with an AM/PM indicator. Additional features may include watchdog timers, alarms and trickle-charging facilities for external back-up batteries; some devices are available which include an integrated crystal for the clock oscillator.

Features

• Real-Time Clock (RTC) Counts Seconds, Minutes, Hours, Date of the Month, Month, Day of the week, and Year with Leap-Year Compensation Valid Up to 2100
• 56-Byte, Battery-Backed, General-Purpose RAM with Unlimited Writes
• I2 C Serial Interface
• Automatic Power-Fail Detect and Switch Circuitry Consumes Less than 500nA in Battery-Backup Mode with Oscillator Running
• Programmable Square-Wave Output Signal

Note

Please note that any defect or non – conformance of this product must be discovered and reported to RS within 20 days of purchase.
