Frequently Asked Questions
How many write/erase cycles can the 24AA64FT-I/OT handle, and what does that mean for high-frequency data logging designs?
The 24AA64FT-I/OT is rated for 1,000,000 write/erase cycles per byte location, making it suitable for applications that update stored values frequently. Combined with a 200-year minimum data retention time, it provides a reliable non-volatile storage solution for industrial sensors and calibration systems.
Does the 24AA64FT-I/OT operate directly from a 1.8 V or 3.3 V microcontroller rail without a level shifter?
Yes. The 24AA64FT-I/OT operates from 1.7 V to 5.5 V supply voltage, so it connects directly to both 1.8 V and 3.3 V microcontroller I2C buses without any level-shifting circuitry, simplifying board design and reducing component count.
What I2C clock frequency does the 24AA64FT-I/OT support, and is it compatible with standard fast-mode I2C peripherals?
The 24AA64FT-I/OT supports a maximum I2C clock frequency of 400 kHz, fully compatible with fast-mode I2C peripherals found on most modern microcontrollers. This allows efficient burst reads of multi-byte configuration blocks with an access time of approximately 3,500 ns.
Is the 24AA64FT-I/OT compliant with RoHS and REACH for export-controlled supply chains?
Yes. The 24AA64FT-I/OT carries a REACH Compliant code and lead-free (Pb-free) designation, meeting RoHS and REACH requirements. This makes it suitable for export to EU markets and for customers with halogen-reduced or green procurement policies.
