Product Overview: M41T11M6TR Real-Time Clock from STMicroelectronics

The M41T11M6TR is a versatile and high-performance Real-Time Clock (RTC) module designed and manufactured by STMicroelectronics, a leader in the semiconductor industry. This RTC provides a full binary-coded decimal (BCD) clock/calendar, which is complemented by 56 bytes of NV SRAM. Its precision and reliability make it an ideal choice for a wide array of applications such as embedded systems, industrial controls, consumer electronics, and IoT devices.

Key Features

• Accurate Timekeeping: The M41T11M6TR maintains precise time with a built-in 32.768 kHz quartz crystal that ensures stable and accurate time-tracking.
• Battery Backup: With an integrated battery-backup input, the device retains timekeeping and SRAM operation even in the absence of power, making it perfect for critical applications where time data must not be lost.
• Programmable Alarm: An onboard programmable alarm can be set to a specific time, allowing for scheduled wake-up events or system alerts.
• Serial Interface: The device features a serial I2C interface, enabling easy integration with microcontrollers and other digital systems for communication and configuration.
• Low Power Consumption: Designed for power-sensitive applications, the M41T11M6TR operates with very low power consumption, contributing to the overall energy efficiency of the system it is integrated into.
• Additional Memory: The additional 56 bytes of NV SRAM can be used for data storage that needs to be preserved during power loss.

Applications

Thanks to its robust feature set, the M41T11M6TR is suited for a variety of applications, including:

• Embedded systems that require accurate timekeeping
• Data loggers that store time-stamped information
