24AA044T-I/SN

Memory IC Overview

The Microchip Technology 24AA044T-I/SN is a 4-kbit (512 x 8) serial electrically erasable programmable read-only memory (EEPROM). It operates within a supply voltage range of 1.7 V to 5.5 V and supports I2C interface clock frequencies up to 1 MHz. The device is housed in an 8-pin SOIC package with surface-mount installation. It features a data retention period of 200 years and functions across an industrial temperature range from -40°C to +85°C.

Memory IC Feature Summary

• Supports high-speed I2C communication with clock frequencies up to 1 MHz
• Operates over a wide supply voltage range from 1.7 V to 5.5 V
• Provides long-term non-volatile data retention for 200 years

Memory IC Applications

• Industrial control systems requiring reliable non-volatile storage
• Consumer electronics utilizing low-voltage operation
• Automotive embedded applications operating in extended temperature ranges

Memory IC Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (-40°C to +85°C) and 'SN' denotes the SOIC-8 package. Confirm the 'T' indicates tape-and-reel packaging suitable for automated assembly. Cross-reference the manufacturer part number against official Microchip documentation to ensure compatibility with system voltage levels and interface requirements before procurement.

Memory IC Selection Notes

Select this component when a 4-kbit EEPROM is required with high-speed I2C performance up to 1 MHz. It is suitable for designs needing operation at voltages as low as 1.7 V. Choose this part over standard speed variants if faster bus communication is necessary. Ensure the PCB layout accommodates the SOIC-8 surface-mount footprint and that the application environment stays within the specified industrial temperature limits.

Memory IC Part Context

This component belongs to the 24AA044 family of serial EEPROMs, which are designed for general-purpose non-volatile memory applications. The family shares common architectural features but varies by speed grade, package type, and temperature rating. The 24AA044 series specifically targets applications requiring higher bus speeds compared to the base 24AA04 models.

Memory IC Replacement Considerations

Direct substitutes include other 24AA044 variants with compatible packages such as 24AA044-I/ST or 24AA044-E/SN, provided the temperature and speed grades match the design requirements.
