M41T11M6F

The M41T11M6F is a low-power, high-precision, CMOS real-time clock (RTC) with integrated SRAM and I2C bus interface from STMicroelectronics. It is designed to provide accurate timekeeping and nonvolatile memory in a compact package.

Description:

The M41T11M6F is a highly integrated RTC module that combines a clock/calendar function with up to 1.5K bytes of nonvolatile SRAM. It features a low-power consumption design, making it suitable for battery-powered applications. The device uses an I2C bus interface for communication with a microcontroller or other system components.

Features:

1. Clock/Calendar function with seconds, minutes, hours, day, date, month, and year.
2. Up to 1.5K bytes of nonvolatile SRAM for data storage.
3. Low-power consumption: 1.8V to 3.6V supply voltage range and low-power modes.
4. I2C bus interface for communication with a microcontroller or other system components.
5. Programmable square wave output for use as a clock signal or for wake-up events.
6. Alarm functions for time-based events.
7. End-of-life battery indicator to signal when the backup battery is running low.
8. Small package size (e.g., 16-pin SOIC or TSSOP).

Applications:

1. Personal computers and laptops for real-time clock and backup RAM.
2. Set-top boxes and home automation systems for timekeeping and data storage.
3. Medical devices for accurate timekeeping and data logging.
4. Industrial control systems for event scheduling and data storage.
5. Automotive applications for timekeeping and nonvolatile memory.
6. Portable electronic devices for timekeeping and data storage.
7. Networking equipment for time synchronization and event scheduling.

The M41T11M6F is a versatile and reliable RTC solution that can be used in a wide range of applications requiring accurate timekeeping, nonvolatile memory, and low power consumption.
