FT24C128A-UTG-B

Overview

The FT24C128A-UTG-B is a 128Kbit serial EEPROM manufactured by Fremont Micro Devices Ltd. It utilizes an I²C interface with a maximum clock frequency of 1 MHz and a write cycle time of 5 ms. The device features a 550 ns access time and operates within a supply voltage range of 1.8V to 5.5V. It is housed in an 8-TSSOP package and supports a wide operating temperature range from -40°C to 85°C.

Feature Summary

• Supports standard two-wire bidirectional serial communication via the I²C interface.
• Includes hardware data protection mechanisms to prevent accidental writes.
• Features self-timed write cycles for efficient operation without external timing control.

Applications

• Low-voltage consumer electronics requiring non-volatile data storage
• Industrial systems needing reliable parameter retention
• Embedded controllers storing calibration or configuration data

Procurement Notes

Verify the specific suffix 'B' against official Fremont Micro Devices documentation, as it may indicate a specific tape-and-reel packaging variant or regional compliance status not universally documented in general distributor listings. Confirm RoHS3 compliance and moisture sensitivity level (MSL) ratings prior to integration into production workflows.

Selection Notes

Select this component when a 128Kbit capacity is required alongside I²C connectivity. Ensure the design accommodates the 1.8V to 5.5V supply range and the 8-TSSOP footprint. Consider the 5ms write cycle duration for system timing constraints during data persistence operations.

Part Context

This part belongs to the FT24C128A series of serial EEPROMs from Fremont Micro Devices. It shares core electrical specifications with variants like the FT24C128A-UTG-T but differs in packaging or reel configuration. The series is designed for CMOS low-power applications.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with existing I²C bus architectures before considering alternative manufacturers.
