Memory IC Procurement Notes

Verify the specific suffix 'E' indicates automotive-grade qualification and '-MS' denotes the MSOP-8 package. Confirm RoHS compliance status through official documentation. Ensure the selected variant matches your required operating temperature range and interface speed specifications before ordering.

Memory IC Selection Notes

Select this component when high-speed 1 MHz I2C performance is required alongside wide voltage operation. The MSOP-8 package suits space-constrained designs. Verify that the -40°C to +125°C temperature range aligns with your environmental requirements compared to standard industrial or commercial alternatives.

Memory IC Part Context

This part belongs to the 24AA04x series of 4-kbit EEPROMs. It shares architectural similarities with other variants like the 24AA044-I/ST but differs in package type and temperature rating. The series utilizes a common 2-wire interface protocol, allowing compatibility with various microcontrollers supporting standard I2C communication.

Memory IC Replacement Considerations

Direct substitutes include 24AA044T-E/MS for reel packaging or 24AA044-E/SN for SOIC-8 packages. Cross-brand replacements require verification of pinout compatibility and voltage thresholds.
