• 1.3 V to 4.4 V I²C bus operating voltage– 4.4 V max. VCC suitable for lithium-ion battery operation
• Low operating current of 35 μA (at 400 kHz I²C speed)
• 32 kHz square wave output is on at power-up. Suitable for driving amicrocontroller in low-power mode. Can be disabled. (M41T62/64)
• Programmable 1 Hz to 32 kHz square wave output (M41T62/64)
• Programmable alarm with interrupt function (M41T62/65)
• 32 kHz crystal oscillator integrates crystal load capacitors, works with highseries resistance crystals
• Oscillator stop detection monitors clock operation
• Accurate programmable watchdog– 62.5 ms to 31 minutes timeout
• Software clock calibration. Timekeeping can be adjusted within ± 2 parts permillion (± 5 seconds per month)
• Automatic leap year compensation
• – 40 to + 85 °C operation• Two package options– Very small 3 x 3 mm, lead-free and halogen-free (ECOPACK2) 16-leadQFN– Ultra small 1.5 x 3.2 mm, lead-free and halogen-free (ECOPACK2) 8-pinceramic leadless chip carrier with embedded 32 kHz crystal - no externaloscillator components required (M41T62)

2.The M41T6x is a low-power serial real-time clock (RTC) with a built-in 32.768 kHz oscillator. Eight registers areused for the clock/calendar function and are configured in binary-coded decimal (BCD) format. Further eightregisters provide status/control of alarm, 32 kHz output, calibration, and watchdog functions. Addresses and dataare transferred serially via a two-line, bidirectional I²C interface. The built-in address register is incrementedautomatically after each WRITE or READ data byte.Functions available to the user include a time-of-day clock/calendar, an alarm interrupt (M41T62/M41T65), a 32kHz output (M41T62/M41T64), a programmable square wave output (M41T62/M41T64), and a watchdog output(M41T65). The eight clock address locations contain the century, year, month, date, day, hour, minute, secondand tenths/hundredths of a second in 24-hour BCD format. Corrections for 28-, 29- (leap year), 30- and 31-daymonths are made automatically.The M41T6x is supplied in two very small packages: a tiny, 3 x 3 mm 16-pin QFN which requires a user-supplied32 kHz crystal, and an ultra-small 1.5 x 3.2 mm LCC with embedded crystal - no external crystal is required.
