STMicroelectronics M41T56-MH6 Real-time Clock

The M41T56-MH6 is a low-power serial real-time clock (RTC) with a built-in 32.768 kHz oscillator (external crystal controlled) and an integrated crystal. Manufactured by STMicroelectronics, a leader in semiconductor solutions, this RTC module is a compact, high-performance timekeeping device that is ideal for a wide range of applications where accurate timekeeping is of the essence.

This RTC provides a wealth of features including 8 bytes of static RAM, and a serial I2C interface to facilitate communication with microcontrollers and other digital devices. It has a byte-addressable interface, which makes the device easy to integrate into existing systems. The M41T56-MH6 is also designed for low power consumption, drawing less than 350nA when operating in battery-backup mode with the oscillator running. This makes it an excellent choice for portable applications where power efficiency is crucial.

The product comes with an array of timekeeping features, such as:

• Counters for seconds, minutes, hours, day, date, month, year, and century
• Automatic leap year compensation valid up to 2100
• Programmable alarm and interrupt function to facilitate event-driven operations
• 48-bit programmable counter for time-of-day alarm

Its robust design ensures that it can maintain accurate timekeeping across a wide temperature range, typically from -40°C to 85°C. The M41T56-MH6 is packaged in an 8-pin SOP (Small Outline Package), making it suitable for space-constrained applications.

Security features such as a software clock calibration and a lockable clock register provide additional utility for applications demanding precise time control and tamper-proof operations. The device's reliability and the support provided by STMicroelectronics make it a trusted choice for applications in industrial systems, consumer electronics, communication infrastructure, and other domains requiring reliable timekeeping.

Overall, the M41T56-MH6 from STMicroelectronics is a versatile and reliable RTC module that combines low power consumption with a rich feature set, tailored to meet the stringent requirements of modern electronic applications.
