What are the key features of 24AA02E48-I/SN?
- Factory-programmed unique 48-bit EUI-48 MAC address eliminating manual address assignment and ensuring network uniqueness across all deployed nodes
- Wide 1.7 V to 5.5 V operating range with up to 0.4 MHz I2C clock and 1,000,000 write/erase cycle endurance for long-life IoT applications
- 256 × 8 bit user-accessible EEPROM in SOIC-8 package for storing device configuration alongside the pre-programmed MAC node identity
What is 24AA02E48-I/SN used for?
24AA02E48-I/SN is used in Ethernet-connected IoT devices and embedded network adapters where each unit requires a globally unique 48-bit EUI-48 MAC address without factory programming overhead. Designers integrate it into industrial gateways and smart home hubs to store both the MAC address and up to 2 Kbits of device configuration data over a single I2C bus at 0.4 MHz. Its 1.7 V minimum supply makes it compatible with energy-harvesting and ultra-low-power sensor nodes that cannot sustain a standard 1.8 V rail.

Frequently Asked Questions
How does the factory-programmed EUI-48 address in 24AA02E48-I/SN simplify Ethernet MAC provisioning on a production line?
24AA02E48-I/SN ships with a globally unique 48-bit EUI-48 MAC address pre-written by Microchip, eliminating the need for in-circuit programming stations that would otherwise flash each board individually, reducing production time and removing the risk of duplicate MAC address assignment across the full 2 Kbit memory.
For a battery-powered Zigbee coordinator storing neighbor table entries, what endurance and retention specs make 24AA02E48-I/SN suitable?
24AA02E48-I/SN supports up to 1,000,000 write/erase cycles per byte location and guarantees a minimum 200-year data retention period, making it durable enough for frequent neighbor table updates over a 10-year product lifetime while preserving stored data through extended power-off intervals.
At what voltage and clock speed does 24AA02E48-I/SN operate, and can it work directly with a 1.8 V MCU without level shifting?
24AA02E48-I/SN operates from 1.7 V to 5.5 V and supports I2C clock frequencies up to 0.4 MHz, allowing direct connection to a 1.8 V microcontroller I2C bus without external level-shift buffers, which simplifies PCB layout and lowers BOM cost in low-power sensor designs.
When is 24AA02E48-I/SN a better fit than a software-generated MAC address for a Wi-Fi IoT module?
Software-generated MACs risk collisions or require cloud-based coordination; 24AA02E48-I/SN provides a standards-compliant, factory-unique 48-bit EUI-48 address in an 8-pin SOIC package that the Wi-Fi host reads over I2C during boot, guaranteeing network uniqueness without any firmware logic or provisioning server infrastructure.
