FT24C08A-UNR-T

Overview

The FT24C08A-UNR-T is an 8-Kbit (1K x 8) serial EEPROM manufactured by Fremont Micro Devices Ltd. It operates within a supply voltage range of 1.8V to 5.5V and supports I²C bus frequencies up to 1 MHz at 5V or 400 kHz at lower voltages. The device features a self-timed write cycle with a maximum duration of 5 ms, hardware write protection via the WP pin, and low standby current consumption below 1 µA. It is housed in an 8-WFDFN package with exposed pad and functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Supports standard two-wire bi-directional serial interface compatible with I²C protocols
• Includes hardware write protection capability through dedicated WP pin
• Features automatic erase-before-write operation for reliable data storage
• Provides high endurance with typical one million write cycles

Applications

• Data logging in battery-powered devices requiring low power consumption
• Configuration storage for microcontroller systems
• Calibration data retention in industrial sensors
• Parameter storage in consumer electronics

Procurement Notes

Verify that the ordering suffix matches the required package type and RoHS compliance status. Confirm the specific tape and reel packaging requirements against the datasheet specifications. Ensure the component meets the intended operating temperature range and voltage levels for your application design.

Selection Notes

Select this component when an 8-Kbit non-volatile memory solution is needed with I²C connectivity. Consider the 1.8V to 5.5V operating range for compatibility with various logic levels. Evaluate the 8-WFDFN package dimensions for PCB layout constraints and thermal management requirements during integration.

Part Context

This part belongs to the FT24C08A series of serial EEPROMs from Fremont Micro Devices. It shares architectural similarities with the FT24C04A and FT24C16A models but offers distinct memory density. The UNR-T suffix indicates the specific surface-mount DFN package and tape-and-reel delivery format.

Replacement Considerations

FT24C08A-ENR-T is listed as a parameter equivalent substitute.
