Frequently Asked Questions
What memory capacity and endurance does the 11AA02E64-I/SN offer for configuration storage?
The 11AA02E64-I/SN provides 2048 bits (256 bytes) of EEPROM storage with a rated endurance of 1,000,000 write/erase cycles and a minimum data retention time of 200 years. This combination of high endurance and long retention makes it reliable for storing device configuration, calibration data, and factory-programmed EUI-64 node identity in industrial embedded systems.
How does the factory-programmed EUI-64 in the 11AA02E64-I/SN simplify IoT device deployment?
The 11AA02E64-I/SN ships with a pre-programmed globally unique 64-bit EUI-64 identifier that eliminates the need for in-system UUID generation or manual serial number management. This reduces firmware complexity in Ethernet, IEEE 802.15.4, and Bluetooth LE applications where each device node must carry a unique 8-byte address from the factory, saving at least 64 bits of configuration overhead per unit.
What interface and supply voltage does the 11AA02E64-I/SN use, and how does that affect PCB integration?
The 11AA02E64-I/SN uses a single-wire serial interface with a maximum clock frequency of 0.1 MHz and operates from a 1.8 V supply, requiring only 1 data line and 2 power pins on an 8-pin SOIC footprint. This 1-wire protocol reduces PCB routing to a single I/O trace, making it ideal for microcontrollers with limited GPIO pins in battery-powered or space-constrained industrial sensor designs.
