24LC044T-I/MS

Memory IC Overview

The Microchip Technology 24LC044T-I/MS is a 4-kbit (512 x 8) Serial Electrically Erasable Programmable Read-Only Memory (EEPROM). It operates within a voltage range of 2.5 V to 5.5 V and features a 2-Wire I²C serial interface with a maximum clock frequency of 400 kHz. The device utilizes an MSOP-8 surface-mount package and supports industrial temperature operation from -40°C to +85°C. Key electrical specifications include a write cycle time of 5 ms, data retention of 200 years, and low power consumption with active read current of 1 mA.

Memory IC Feature Summary

• Supports high-speed I²C communication with standard mode up to 400 kHz
• Provides non-volatile data storage with long-term retention capabilities
• Operates across a wide supply voltage range for flexible system integration

Memory IC Applications

• Industrial control systems requiring persistent parameter storage
• Consumer electronics needing configuration data retention
• Embedded devices utilizing I²C bus architectures

Memory IC Procurement Notes

Verify the specific suffix 'I/MS' confirms the industrial temperature grade (-40°C to +85°C) and MSOP-8 package. Confirm the 'T' indicates tape-and-reel packaging suitable for automated assembly. Ensure compatibility with the target I²C address configuration and voltage levels before finalizing procurement orders.

Memory IC Selection Notes

Select this component when a compact 4-kbit EEPROM is required for I²C-based designs. The MSOP-8 package offers space efficiency for dense PCB layouts. Consider the 2.5 V minimum operating voltage if designing for lower-power applications compared to 5 V-only alternatives.

Memory IC Part Context

This part belongs to the 24LC04B family of Serial EEPROMs. It shares functional similarities with other variants in the series but differs in package type and temperature rating. The MSOP-8 variant provides a smaller footprint compared to SOIC or TSSOP options while maintaining compatible pin functions.

Memory IC Replacement Considerations

Direct substitutes include other 24LC04B variants with different packages such as 24LC04BT-I/ST (TSSOP-8) or 24LC04BT-I/MUY (UDFN-8), provided the physical footprint change is acceptable in the design.
