FT24C64A-UNR-T

Overview

The FT24C64A-UNR-T is a non-volatile EEPROM memory IC manufactured by Fremont Micro Devices Ltd. It provides a storage capacity of 64Kb, organized as 8K x 8 bits. The device utilizes an I2C interface with a maximum clock frequency of 1 MHz and features a typical access time of 500 ns. It operates within a supply voltage range of 1.8V to 5.5V and supports a write cycle time of 5ms for both word and page operations. The component is housed in an 8-DFN (2x3) surface-mount package and is rated for operation across a temperature range of -40°C to 85°C.

Feature Summary

• Supports high-speed I2C communication protocols up to 1 MHz
• Provides reliable non-volatile data retention without power
• Operates efficiently across a wide supply voltage spectrum

Applications

• Data logging systems requiring persistent storage
• Configuration parameter storage in embedded controllers
• Calibration data retention in industrial sensors

Procurement Notes

Verify the specific suffix 'UNR-T' against official Fremont Micro Devices documentation to confirm the exact package type and tape-and-reel specifications. Ensure that the ordering information matches the required 8-DFN form factor and operational voltage ranges specified in the manufacturer's datasheet before finalizing procurement.

Selection Notes

Select this component when a compact 8-pin surface-mount solution is required for 64Kb I2C EEPROM applications. Consider the 1.8V minimum operating voltage for low-power designs and verify compatibility with the host system's I2C bus speed limitations and electrical characteristics.

Part Context

This part belongs to the FT24C64A series of serial EEPROMs from Fremont Micro Devices Ltd. The series offers various packaging options including DFN and TSSOP configurations. The UNR-T designation specifically indicates the tape-and-reel packaging format suitable for automated surface-mount assembly processes.

Replacement Considerations

Direct substitutes include other 64Kb I2C EEPROMs from manufacturers such as STMicroelectronics or Microchip, provided they match the 8-DFN package and 1.8V-5.5V voltage range. Verify pinout compatibility and software register alignment before replacement.
