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.
