FT24C64A-ETG-T

Overview

The FT24C64A-ETG-T is a serial EEPROM manufactured by Fremont Micro Devices Ltd. It features a memory density of 65,536 bits organized as 8K x 8 bits. The device supports I2C interface communication with a maximum clock frequency of 1 MHz. It operates within a voltage range of 1.7V to 5.5V and offers data retention of at least 40 years. The component is housed in an SOT-23-5 package.

Feature Summary

• Supports standard and fast-mode I2C bus protocols for reliable two-wire serial communication.
• Provides high endurance with one million write/erase cycles for long-term durability.
• Ensures data integrity through hardware write protection mechanisms.
• Operates across extended industrial temperature ranges for robust performance.

Applications

• Consumer electronics requiring non-volatile configuration storage
• Industrial control systems needing parameter logging
• Automotive modules for calibration data retention

Procurement Notes

Verify the manufacturer designation matches Fremont Micro Devices Ltd or its authorized successor entities. Confirm the specific suffix ETG-T corresponds to the SOT-23-5 package and tape-and-reel delivery format. Ensure compliance with RoHS directives if required for your assembly process. Cross-reference the datasheet revision date to confirm electrical characteristics match your design requirements.

Selection Notes

Select this component when a small footprint is critical due to the SOT-23-5 package. Choose it for applications requiring low power consumption during standby modes. Consider it for systems operating below 3.3V where the 1.7V minimum supply voltage provides flexibility. Verify that the I2C address pins are configured correctly for your bus topology.

Part Context

This part belongs to the FT24CxxA series of serial EEPROMs designed for cost-effective data storage. It shares functional similarities with other industry-standard I2C EEPROMs but offers specific voltage and package options tailored for compact designs. The series is commonly used in portable devices and embedded systems.

Replacement Considerations

Direct substitutes include M24C64-WMN6P from STMicroelectronics and CAT24C64WIE-GT3 from onsemi. Verify pin compatibility and voltage levels before substitution. Check package dimensions to ensure mechanical fit within the existing PCB layout.
