STMicroelectronics | M41T00SM6F

The M41T00SM6F 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 M41T00S Serial Access TIMEKEEPER® SRAM is a low power serial RTC with a builtin 32.768 kHz oscillator (external crystal controlled). Eight bytes of the SRAM (see Table 2 on page 13) 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 I2C interface. The built-in address register is incremented automatically after each WRITE or READ data byte.

Features:

• 2.0 to 5.5 V clock operating voltage
• Counters for seconds, minutes, hours, day, date, month, year, and century
• Software clock calibration
• Automatic switchover and deselect circuitry (fixed reference)
• VCC= 2.7 to 5.5V
• 2.5V=VPFD=2.7V
• Serial interface supports I2C bus (400 kHz protocol)
• Low operating current of 300 µA
• Oscillator stop detection
• Battery or SuperCapTM backup
• Operating temperature of –40 to 85°C
• Ultra-low battery supply current of 1 µA
