Procurement Notes

Verify the exact datasheet version from Fremont Micro Devices Ltd before procurement. Confirm that the 8-SOP package matches your PCB footprint requirements. Ensure the operating voltage range aligns with your system's power supply rails. Check for any specific ordering suffixes that may indicate tape-and-reel packaging variations.

Selection Notes

Select this component when a 1Mbit EEPROM with I2C interface is required. Consider the 400 kHz clock speed for moderate data throughput needs. The wide voltage range supports both low-power and standard logic applications. Verify compatibility with existing microcontroller I2C peripherals regarding pull-up resistor values and address configuration.

Part Context

This part belongs to the FT24C1024A series of serial EEPROMs from Fremont Micro Devices. It offers high-density storage in a compact surface-mount package. The series is designed for applications requiring reliable non-volatile data retention without complex interface protocols.

Replacement Considerations

Direct substitutes include other 1Mbit I2C EEPROMs from manufacturers like Microchip or STMicroelectronics. Ensure pinout compatibility and voltage specifications match. Verify that the substitute device supports the same 400 kHz clock frequency and 5 ms write cycle time.
