M41T81SMY6F

The M41T81SMY6F from STMicroelectronics is a low-power serial real-time clock (RTC) with a built-in 32.768 kHz oscillator (external crystal controlled). It has eight bytes of SRAM for the clock/calendar function and is configured in binary coded decimal (BCD) format. The RTC is powered by a 1.8V to 5.5V supply and has a maximum current consumption of 100µA. It is available in an 18-pin SOIC package.

Key Features:

• Low power consumption: 100µA (max.)
• Built-in 32.768 kHz oscillator (external crystal controlled)
• Eight bytes of SRAM for the clock/calendar function
• BCD format
• 1.8V to 5.5V supply voltage
• 18-pin SOIC package

Benefits:

• The M41T81SMY6F is a complete RTC solution in a single package, which simplifies circuit design and reduces component count.
• Its low power consumption makes it ideal for battery-powered applications.
• Its built-in oscillator eliminates the need for an external oscillator, further simplifying circuit design.
• Its eight bytes of SRAM allow for storage of the clock/calendar function, as well as other data.
