FT24C128A-ESG-T

Overview

The FT24C128A-ESG-T is a 128 Kbit (16K x 8) serial EEPROM manufactured by Fremont Micro Devices Ltd. It utilizes an I²C interface with a maximum clock frequency of 1 MHz and features an 8-SOP (0.154", 3.90mm wide) surface-mount package. The device operates within a supply voltage range of 1.8V to 5.5V and supports a working temperature range from -40°C to +85°C. Key electrical parameters include a write cycle time of 5ms per word or page and an access time of 500 ns.

Feature Summary

• Supports standard two-wire bidirectional I²C serial communication interface
• Includes hardware write protection functionality for data security
• Features built-in power-on reset circuitry for reliable initialization

Applications

• Low-voltage consumer electronics requiring non-volatile storage
• Industrial control systems operating in extended temperature ranges
• Embedded devices needing configuration parameter retention

Procurement Notes

Verify the specific suffix 'ESG' against official Fremont Micro Devices documentation to confirm the exact package type and tape-and-reel specifications, as distributor listings may vary. Ensure the component meets RoHS3 compliance requirements if mandated by your assembly process. Cross-reference the manufacturer part number directly with the datasheet to avoid confusion with similar FT24C series variants that may have different pinouts or electrical characteristics.

Selection Notes

Select this component when a 128 Kbit capacity is required alongside a compact 8-pin SOP footprint. The 1.8V minimum operating voltage makes it suitable for modern low-power designs, while the 1 MHz I²C speed ensures efficient data transfer. Consider the 500 ns access time for applications demanding faster read operations compared to standard EEPROMs. Verify that the system design accommodates the 5 ms write cycle duration for proper timing management.

Part Context

This part belongs to the FT24C128A series of serial EEPROMs from Fremont Micro Devices Ltd. The series is designed for low-voltage and low-power applications using advanced CMOS technology. Other members of the family include variants with different packaging options such as TSSOP or DFN, but all share the same core 128 Kbit memory organization and I²C interface capabilities.
