24AA044T-E/MS

Memory IC Overview

The Microchip Technology 24AA044T-E/MS is a 4 kbit (512 x 8) serial electrically erasable programmable read-only memory (EEPROM). It features a 2-Wire I2C interface with a maximum clock frequency of 1 MHz. The device operates within a supply voltage range of 1.7 V to 5.5 V and supports surface-mount installation in an MSOP-8 package. It offers a data retention period of 200 years, active read current up to 3 mA, and functions reliably across an extended temperature range from -40°C to +125°C.

Memory IC Feature Summary

• Supports high-speed 1 MHz I2C communication for efficient data transfer
• Operates on low voltage supplies ranging from 1.7 V to 5.5 V
• Provides long-term data retention capability of 200 years
• Designed for reliable operation in extended industrial temperature environments

Memory IC Applications

• Industrial control systems requiring non-volatile data storage
• Automotive electronics operating under harsh thermal conditions
• Consumer devices utilizing low-power serial memory interfaces
• Embedded systems needing compact surface-mount EEPROM solutions

Memory IC Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature grade (-40°C to +125°C) and 'MS' denotes the MSOP-8 package. Confirm the 'T' suffix corresponds to tape-and-reel packaging for automated assembly. Ensure compatibility with 1.7 V minimum supply requirements before integration into low-voltage designs.

Memory IC Selection Notes

Select this component when high-speed 1 MHz I2C performance is required alongside extended temperature reliability. The MSOP-8 package suits space-constrained printed circuit board layouts. Verify that the 1.7 V minimum operating voltage aligns with the system power rail, as lower voltage variants may not function correctly below this threshold.

Memory IC Part Context

This part belongs to the 24AA044 series of serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with other 4 kbit I2C EEPROMs but is distinguished by its extended temperature rating and specific package configuration. The series is designed for applications demanding robust non-volatile memory in compact form factors.

Memory IC Replacement Considerations

Direct substitutes include other 24AA044 variants with compatible pinouts and electrical characteristics. Verify package equivalence between MSOP-8 and alternative small-outline packages. Ensure replacement parts support the same 1 MHz clock speed and 1.7 V minimum operating voltage for functional parity.
