General Description

The Microchip Technology Inc.

24AA256UID is a 32K x 8 (256 Kbit) Serial Electrically Erasable PROM with preprogrammed EUI-48 and EUI-64 node addresses and a 32-bit Unique ID, capable of operation across a broad voltage range (1.7V to 5.5V).

This device also has a page write capability of up to 64 bytes of data.

Key Features

  • Preprogrammed 32-Bit Serial Number: - Unique across all UID-family EEPROMs - Scalable to 48-bit, 64-bit, 128-bit, 256-bit, and other lengths.
  • Preprogrammed Globally Unique, 48-bit or 64-bit Node Address: - Compatible with EUI-48™ and EUI-64™.
  • Codes Stored in Permanently Write-Protected Upper 1/8th of EEPROM Array.
  • Single Supply with Operation Down to 1.7V.
  • Low-Power CMOS Technology: - Active current 400 µA, typical - Standby current 100 nA, typical.
