Applications
The 24AA64-I/SN is ideal for storing configuration data, calibration parameters, and firmware settings in embedded systems such as industrial controllers, consumer electronics, and smart meters. Its wide voltage range and I2C interface make it a natural fit for microcontroller-based designs using 1.8V to 5V rails. The high endurance and long data retention also suit applications requiring frequent non-volatile writes, such as data logging and event counters.

Frequently Asked Questions
What is the maximum clock frequency supported by the 24AA64-I/SN?
The 24AA64-I/SN supports a maximum I2C clock frequency of 400 kHz (fast mode), enabling efficient serial communication in time-sensitive embedded applications operating at 1.7V to 5.5V supply voltage.
How many write/erase cycles can the 24AA64-I/SN endure before data reliability degrades?
The 24AA64-I/SN is rated for a minimum of 1,000,000 write/erase cycles per byte, ensuring long-term reliability even in applications with frequent non-volatile memory updates, such as data logging at 400 kHz.
Can multiple 24AA64-I/SN devices share the same I2C bus, and how many?
Yes, up to 8 devices can share the same I2C bus by configuring the 3 hardware address pins (A0, A1, A2) independently, providing up to 512Kbit (64KB) of total non-volatile storage at 1.7V to 5.5V.
What supply voltage range does the 24AA64-I/SN support, and is it compatible with 1.8V microcontrollers?
The 24AA64-I/SN operates from 1.7V to 5.5V, making it fully compatible with 1.8V, 2.5V, 3.3V, and 5V microcontroller systems; this wide range eliminates the need for level shifters in most low-power and mixed-voltage designs.
