M41T00M6E

Real Time Clock Overview

The STMicroelectronics M41T00M6E is a low-power serial real-time clock (RTC) IC providing clock and calendar functions via an I2C interface. It operates within a supply voltage range of 2V to 5.5V, with a maximum current consumption of 70µA at 2V. The device features an 8-SOIC package (3.90mm width) and supports industrial operating temperatures from -40°C to +85°C. Time and date are stored in BCD format, including automatic leap year correction. The component is classified as obsolete and no longer manufactured.

Real Time Clock Feature Summary

• I2C 2-wire serial interface supporting standard communication protocols
• Automatic leap year correction valid until the year 2100
• Battery backup supply range of 2.5V to 3.5V for continuous operation during power loss

Real Time Clock Applications

• General-purpose timekeeping in embedded systems requiring I2C connectivity
• Data logging devices needing accurate timestamping capabilities
• Consumer electronics utilizing surface-mount technology constraints

Real Time Clock Procurement Notes

The M41T00M6E is officially marked as obsolete and no longer manufactured by STMicroelectronics. Verification of authenticity is critical when sourcing from secondary markets, as availability is limited to existing stock. Buyers should confirm the specific manufacturing date code and physical condition upon receipt. Regulatory compliance data indicates the part does not meet current RoHS standards.

Real Time Clock Selection Notes

Designers requiring active components should consider the M41T00M6F as a direct replacement within the same family. The M6F variant maintains identical pinout and functional specifications while offering updated manufacturing status. Evaluation of long-term supply chain stability is recommended before finalizing designs that rely on this discontinued part number.

Real Time Clock Part Context

This component belongs to the M41T00 series of serial real-time clocks produced by STMicroelectronics. The series is characterized by low power consumption and simple I2C integration. The M6 suffix denotes the specific 8-SOIC package configuration with industrial temperature rating, distinguishing it from other package variants like TSSOP or DIP.

Real Time Clock Replacement Considerations

The M41T00M6F is listed as a direct substitute. It shares the same electrical characteristics and package dimensions. No functional changes are required for pin-compatible upgrades.
