24AA044T-E/SN

Memory IC Overview

The Microchip Technology 24AA044T-E/SN is a 4-kbit (512 x 8) serial electrically erasable programmable read-only memory (EEPROM). It features an I2C (2-Wire) 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 8-SOIC package. It offers a data retention period of 200 years and functions across an extended temperature range from -40°C to +125°C. Active read current is specified at a maximum of 3 mA.

Memory IC Feature Summary

• Supports high-speed I2C communication with a maximum clock frequency of 1 MHz for efficient data transfer.
• Provides extended industrial operating temperature capability ranging from -40°C to +125°C.
• Ensures long-term data integrity with a documented retention period of 200 years.
• Operates over a wide supply voltage range from 1.7 V to 5.5 V for flexible system integration.

Memory IC Applications

• Industrial control systems requiring reliable non-volatile storage in harsh environments
• Consumer electronics utilizing low-voltage power supplies
• Automotive applications needing extended temperature range compliance
• Embedded systems storing configuration parameters or calibration data

Memory IC Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature grade (-40°C to +125°C) compared to standard industrial grades. Confirm the 'SN' suffix corresponds to the SOIC-8 package and 'T' denotes tape-and-reel packaging. Ensure compatibility with the target I2C bus speed, as this variant supports up to 1 MHz, unlike slower 100 kHz versions. Check RoHS compliance status for environmental regulations.

Memory IC Selection Notes

Select this component when high-speed I2C access is required alongside extended temperature operation. Compare against the 24AA04 series for standard industrial temperatures if cost is a primary driver. Consider the 24LC04 series for pin-compatible alternatives with different speed or voltage characteristics. Evaluate package constraints to ensure the SOIC-8 footprint fits the design. Verify that the 1.7 V minimum voltage aligns with the system's lowest operating condition.

Memory IC Part Context

This part belongs to the Microchip 24AA04 family of serial EEPROMs. It shares architectural similarities with the 24LC04 and 24FC04 series but differs in speed and temperature specifications. The 24AA044 variant specifically targets applications demanding higher throughput than the base 100 kHz models while maintaining broad voltage compatibility.

Memory IC Replacement Considerations

The 24AA04T-I/SN serves as a lower-temperature alternative (-40°C to +85°C). The 24LC044T-I/SN offers similar functionality with potentially different electrical characteristics. Cross-reference datasheets for exact pinout and timing parameter compatibility before substitution.
