Real Time Clocks ICs

M41T0M6E Description

The M41T0M6E is a low-power Real-Time Clock (RTC) and calendar IC from STMicroelectronics, designed for precision timekeeping in embedded systems. Housed in an 8-SOIC package, it operates over a 2V to 5.5V supply range, making it suitable for battery-backed or low-voltage applications. The device communicates via I2C interface, ensuring easy integration with microcontrollers. With a timekeeping current as low as 1.2µA, it excels in power-sensitive designs. Though marked Obsolete, it remains relevant for legacy systems requiring reliable clock/calendar functionality with HH:MM:SS format.

M41T0M6E Features

• Ultra-Low Power Consumption: 1.2µA to 31µA timekeeping current (3V–5.5V), ideal for battery-operated devices.
• Wide Voltage Range: Supports 2V to 5.5V, compatible with 3.3V and 5V systems.
• I2C Interface: Simplifies communication with host controllers.
• Surface-Mount Design: 8-SOIC package (MSL 1) for compact PCB layouts.
• High Reliability: ROHS3 Compliant and REACH Unaffected, ensuring environmental compliance.
• Precision Timekeeping: Maintains accurate clock/calendar with seconds, minutes, hours, day, date, month, and year tracking.

M41T0M6E Applications

• Industrial Automation: Timestamping for data loggers and control systems.
• Consumer Electronics: Clocks in appliances, smart meters, and IoT edge devices.
• Backup Power Systems: Battery-backed RTC for servers or telecom equipment.
• Medical Devices: Time-sensitive logging in portable health monitors.
• Legacy Upgrades: Replacement for obsolete RTCs in existing designs.

Conclusion of M41T0M6E

The M41T0M6E offers a robust, low-power RTC solution for applications demanding precise timekeeping with minimal energy use. While discontinued, its wide voltage range, I2C compatibility, and compact form factor make it a practical choice for legacy or low-power designs. Engineers valuing reliability and compliance (ROHS3, REACH) will find it suitable for industrial, consumer, and medical systems requiring accurate time synchronization.
