Frequently Asked Questions
What makes the 25AA02E48-I/SN different from standard SPI EEPROMs?
The 25AA02E48-I/SN includes a factory pre-programmed EUI-48 MAC address stored in a read-only section of the memory, providing a guaranteed globally unique 48-bit hardware identifier for Ethernet, Wi-Fi, and other network interfaces without additional provisioning steps.
What are the operating voltage and clock speed specifications of the 25AA02E48-I/SN?
The 25AA02E48-I/SN operates from 1.8V to 5.5V. At 2.5V to 5.5V it supports up to 5MHz SPI clock, and at 1.8V to 2.5V it operates at up to 3MHz. It also supports 10MHz operation in some configurations, making it compatible with a wide range of host processors.
How much user-accessible storage does the 25AA02E48-I/SN provide?
The 25AA02E48-I/SN offers 2K bits of total storage organized as 256 bytes (256 x 8). Part of the memory stores the pre-programmed EUI-48 address in a protected area, while the remaining bytes are available for user data storage with 1,000,000 erase/write cycle endurance.
Is the 25AA02E48-I/SN RoHS compliant and what package does it use?
Yes, the 25AA02E48-I/SN is fully RoHS and REACH compliant with Pb-free construction (JESD-609 e3). It comes in an SOIC-8 package (JESD-30 code R-PDSO-G8), a widely available and easy-to-solder surface-mount format.
What are typical applications for the 25AA02E48-I/SN?
Typical applications include Ethernet controllers, IoT edge devices, industrial network nodes, smart home hubs, and any embedded system requiring a unique MAC address for network identity. It simplifies product manufacturing by eliminating the need for manual MAC address programming during production.
