FT24C64A-UTG-B

Overview

The FT24C64A-UTG-B is a serial CMOS EEPROM manufactured by Fremont Micro Devices Ltd. It features a storage capacity of 64K bits, internally organized as 8192 words of 8 bits each. The device utilizes an I2C (Two-Wire) serial interface for data communication. It operates within a supply voltage range of 1.8V to 5.5V and supports industrial temperature grades from -40°C to +85°C. The component is housed in an 8-pin TSSOP surface-mount package.

Feature Summary

• Supports standard I2C two-wire serial communication protocol
• Provides non-volatile data retention without power
• Operates across a wide voltage range compatible with various logic levels

Applications

• Data logging systems requiring persistent storage
• Configuration memory for embedded controllers
• Calibration data storage in industrial sensors

Procurement Notes

Verify the specific suffix UTG-B against official Fremont Micro Devices documentation to confirm the exact tape-and-reel packaging configuration and lead-free status. Ensure the ordering part number matches the required package variant and compliance specifications before finalizing procurement orders.

Selection Notes

Select this component when a small-footprint EEPROM with I2C interface is required for low-power applications. Consider the 1.8V minimum operating voltage for compatibility with modern low-voltage microcontrollers. Verify that the TSSOP-8 package dimensions fit the target PCB layout constraints.

Part Context

This part belongs to the FT24CxxA series of serial EEPROMs from Fremont Micro Devices. The series offers various densities optimized for cost-sensitive consumer and industrial electronics. The FT24C64A specifically targets applications needing moderate storage density in a compact form factor.

Replacement Considerations

Cross-reference with other 64Kb I2C EEPROMs such as the AT24C64 or M24C64 families. Verify pinout compatibility and voltage level tolerances before substituting to ensure functional equivalence in the existing circuit design.
