24LC044T-E/SN

Memory IC Overview

The 24LC044T-E/SN is a 4Kbit (512 x 8) serial Electrically Erasable Programmable Read-Only Memory (EEPROM) manufactured by Microchip Technology. It features an I2C (2-wire) serial interface with a maximum clock frequency of 400 kHz. The device operates within a supply voltage range of 2.5V to 5.5V and is housed in an 8-pin SOIC package. It supports industrial temperature ranges and includes hardware write protection capabilities.

Memory IC Feature Summary

• Advanced I2C serial interface for efficient data communication
• Hardware write protection to ensure data integrity
• Non-volatile storage with long-term data retention

Memory IC Applications

• Data logging systems requiring reliable non-volatile storage
• Industrial control units needing parameter configuration storage
• Consumer electronics utilizing address pin configurations

Memory IC Procurement Notes

Verify the specific suffix 'E' indicates extended temperature range and 'SN' denotes the SOIC-8 package. Confirm that the 'T' suffix corresponds to tape and reel packaging if required for automated assembly. Ensure compatibility with the target system's I2C bus voltage levels before integration.

Memory IC Selection Notes

Select this component when a 4Kbit capacity is sufficient for application requirements. The I2C interface minimizes pin count, making it suitable for space-constrained designs. Consider the 400 kHz speed limit for high-frequency applications; faster alternatives may be needed for higher throughput requirements.

Memory IC Part Context

This part belongs to Microchip's 24LC series of serial EEPROMs. These devices are designed for low-power applications and offer high reliability. The 24LC044 variant specifically provides address pins for multiple device addressing on the same bus, enhancing system flexibility compared to fixed-address variants.

Memory IC Replacement Considerations

Direct substitutes include other 4Kbit I2C EEPROMs from Microchip such as the 24LC04B series, provided pinout and electrical specifications match. Verify package compatibility and operating voltage ranges when considering cross-brand replacements.
