24AA02E48T-E/SN

Memory IC Overview

The Microchip Technology 24AA02E48T-E/SN is a 2 Kbit serial EEPROM featuring an I²C interface. It operates within a supply voltage range of 1.7V to 5.5V and supports clock frequencies up to 400 kHz. The device includes a factory-programmed, globally unique EUI-48™ node address permanently stored in the upper half of the memory array. It utilizes an 8-lead SOIC package and is rated for extended temperature operation from -40°C to +125°C.

Memory IC Feature Summary

• Factory-programmed globally unique 48-bit node address compatible with EUI-48™ standards
• Low-power CMOS technology supporting operation down to 1.7V
• I²C compatible 2-wire serial interface with Schmitt trigger inputs for noise suppression
• Extended temperature range capability suitable for automotive applications

Memory IC Applications

• IoT terminal device identity authentication
• Firmware binding and anti-counterfeiting traceability
• Device lifecycle management requiring hardware-level credentials

Memory IC Procurement Notes

Verify that the ordering suffix 'E' corresponds to the Automotive grade (-40°C to +125°C) rather than Industrial grade. Confirm the 'SN' suffix indicates the 8-lead SOIC package. Ensure the 'T' suffix matches the required tape-and-reel packaging format for automated assembly processes.

Memory IC Selection Notes

Select this component when a permanent, unalterable hardware identifier is required for system security. The EUI-48™ address provides a standardized method for device identification without software overhead. Choose this specific variant over standard EEPROMs if compliance with IEEE OUI standards is necessary for network addressing or secure boot protocols.

Memory IC Part Context

This part belongs to the 24AA02XEXX family of 2 Kbit serial EEPROMs. It shares architectural similarities with the 24AA025E48 but differs in page size and address pin availability. Unlike general-purpose memory devices, this series integrates a dedicated write-protected region specifically allocated for manufacturing-assigned unique identifiers.

Memory IC Replacement Considerations

Direct substitutes include other 24AA02E48 variants with different temperature grades (e.g., Industrial 'I') or packages (e.g., SOT-23). Cross-vendor equivalents must be verified for identical EUI-48™ allocation and I²C timing characteristics.
