M41T0M6F Datasheet

Real Time Clock


The M41T0M6F real-time clock is a low power serial real-time clock with a built-in 32.768 kHz oscillator (external crystal controlled). Eight registers are used for the clock/calendar function and are configured in binary coded decimal (BCD) format. Addresses and data are transferred serially via a two-line bidirectional bus. The built-in address register is incremented automatically after each WRITE or READ data byte. M41T0M6F Features • Counters for seconds, minutes, hours, day, date, month, years, and century• 32 KHz crystal oscillator integrating load capacitance (12.5 pF) providing exceptional oscillator stability and high crystal series resistance operation• Oscillator stop detection monitors clock operation• Serial interface supports I2C bus (400 kHz protocol)• Low standby current 0.9 μA (typ at 3 V)• 2.0 to 5.5 V clock operating voltage• Special software programmable output• Operating temperature of –40 to 85 °C
