M41T00SC64MY6E

Real Time Clock Overview

The M41T00SC64MY6E is a Real-Time Clock (RTC) integrated circuit manufactured by STMicroelectronics. It features an I2C bus compatible interface and includes a built-in 64Kbit (8192 x 8) EEPROM for data storage. The device supports clock/calendar functions with date formats including YY-MM-DD-dd and time formats HH:MM:SS. It operates on a supply voltage ranging from 2.7V to 5.5V and is designed for surface mount installation in 18-SOX or 18-SOIC packages with a crystal. The component ensures accurate timekeeping through an external crystal controlled oscillator.

Real Time Clock Feature Summary

• Integrated 64Kbit EEPROM for non-volatile data retention alongside RTC functionality
• I2C bus compatible serial interface for simplified system connectivity
• Built-in leap year compensation for calendar accuracy

Real Time Clock Applications

• Consumer electronics requiring precise timekeeping and data logging
• Industrial control systems needing reliable clock/calendar synchronization
• Embedded devices utilizing I2C communication protocols

Real Time Clock Procurement Notes

Verify the specific package variant, such as 18-SOX or 18-SOIC, matches the target PCB footprint requirements. Confirm that the operating temperature range aligns with the environmental conditions of the intended application. Ensure compatibility with the system's I2C bus voltage levels before integration.

Real Time Clock Selection Notes

Select this component when both real-time clocking and significant non-volatile memory storage are required within a single IC. Consider the I2C interface constraints and available board space for the external crystal. Evaluate the power consumption characteristics against the system's battery life expectations if applicable.

Real Time Clock Part Context

This part belongs to the M41T00S family of serial access timekeepers. These devices combine low-power RTC capabilities with SRAM or EEPROM storage. The M41T00SC64MY6E specifically integrates 64Kbit EEPROM, distinguishing it from variants with smaller memory capacities or different package options within the same product line.

Real Time Clock Replacement Considerations

Check for direct substitutes within the M41T00S series that offer identical 64Kbit EEPROM capacity and I2C compatibility. Verify pinout and package dimensions match exactly to ensure mechanical interchangeability without redesigning the PCB layout.
