The M41T11-MH6 is a low-power serial real-time clock (RTC) with a built-in 32.768 kHz oscillator (external crystal controlled) and an embedded lithium battery. Manufactured by STMicroelectronics, a leader in semiconductor solutions, this RTC provides a full binary-coded decimal (BCD) clock/calendar and 56 bytes of SRAM. It is designed for applications requiring accurate timekeeping and data storage without the need for a constant power supply.
This device includes features that make it particularly well-suited for real-time applications in consumer electronics, industrial control systems, and handheld devices. With an I2C interface for communication, the M41T11-MH6 allows for easy integration into a variety of microcontroller-based systems. It supports a clock/calendar function that provides seconds, minutes, hours, day, date, month, and year information, and accounts for leap years up to the year 2100.
The M41T11-MH6 offers a range of benefits and features, including:
- Low Energy Consumption: Its low power design ensures minimal impact on battery life, making it ideal for battery-powered devices.
- Automatic Power-Fail Detect: The built-in power sense circuit detects power failures and automatically switches to the battery supply, maintaining time and date operation.
- Programmable Alarm: A programmable alarm function allows users to set up alarms that can trigger external devices or notify when a specific time is reached.
- 56 Bytes of SRAM: Additional SRAM provides scratchpad memory space, useful for storing data that needs to be preserved during power loss.
- Robust Timekeeping: Accurate to ±5 ppm at 25°C, the M41T11-MH6 maintains precise timekeeping, essential for time-critical applications.
The compact packaging and robust feature set of the M41T11-MH6 make it an excellent choice for designers looking for a reliable and versatile RTC solution. Its integration of power management and memory functions, along with a simple interface, ensures it can meet the demands of a wide array of applications, maintaining accurate time and configuration settings even under adverse conditions.
