Key Features

  • 64 Kbit (8 KB) I2C serial EEPROM with 400 kHz fast-mode bus support
  • Ultra-wide supply voltage of 1.7 V to 5.5 V for mixed-voltage system compatibility
  • 1,000,000 write/erase cycle endurance for high-reliability data logging
  • 200-year minimum data retention time for long-life embedded storage
  • Tiny 5-pin SOT-23 package ideal for space-constrained portable designs
  • RoHS and REACH compliant with lead-free assembly process support

Applications

The 24AA64FT-I/OT is well suited for storing calibration data, configuration parameters, and user settings in battery-powered IoT devices, wearable electronics, and portable medical instruments. Its tiny SOT-23 footprint and wide 1.7 V to 5.5 V supply range make it a natural fit for low-voltage MCU designs that require persistent non-volatile memory with minimal board space.

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.
