STMicroelectronics | M41T11M6F

The M41T11M6F is a part of M41T series I2C RTC. It has an operating temperature ranging from -40 °C to +85 °C and it comes in SOIC-8 Packaging.

The M41T11is a low power serial real time clock with 56 bytes of NVRAM. A built-in 32.768kHz oscillator (external crystal controlled) and the first 8 bytes of the RAM 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 bi-directional bus. The built-in address register is incremented automatically after each write or read data byte.

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
• Serial interface supports I2C bus (100 kHz protocol)
• Ultra-low battery supply current of 0.8 µA (typ at 3V)
• 2.0 to 5.5 V clock operating voltage
• Automatic switchover and deselect circuitry
• 56 bytes of general purpose RAM
• Software clock calibration to compensate crystal deviation due to temperature
• Automatic leap year compensation
• Operating temperature of -40 to 85°C
• Packaging includes a 28-lead SOIC and SNAPHAT® top (to be ordered separately; 3.3V to 5.0V supply voltage only)
• RoHS compliant
• Lead-free second level interconnect
