FT24C04A-KTR-T

Overview

The FT24C04A-KTR-T is a 4-Kbit serial Electrically Erasable PROM (EEPROM) manufactured by Fremont Micro Devices Ltd. It features an I2C-compatible two-wire serial interface and operates with a single supply voltage of 5.0V. The device is organized as 512 words of 8 bits each, providing a total memory capacity of 4096 bits. It supports hardware write protection for the upper half of the memory block and includes a page-write buffer with a page length of eight bytes. The component guarantees 1,000,000 erase/write cycles and data retention exceeding 200 years.

Feature Summary

• I2C-compatible two-wire serial interface bus
• Hardware write protection for the upper half of the memory block
• Page-write buffer capability with eight-byte page length
• Self-timed write cycle including auto-erase

Applications

• General-purpose non-volatile data storage in industrial systems
• Configuration memory for electronic devices requiring 5V operation
• Data logging applications in commercial temperature range environments

Procurement Notes

Verify the manufacturer designation as Fremont Micro Devices Ltd against the specific datasheet provided by the supplier. Confirm that the operating voltage is strictly limited to 5.0V, as this variant does not support lower voltage ranges like 2.5V or 1.8V found in other EEPROM families. Ensure the package type matches the required PCB footprint, typically available in DIP or SOIC formats for this series.

Selection Notes

Select this component when a 5.0V-only supply system requires reliable non-volatile storage with I2C connectivity. It is suitable for applications needing hardware write protection for critical data segments. Consider alternative low-voltage variants if the system operates below 2.5V. Verify the temperature grade requirements, as commercial grades are limited to 0°C to +70°C unless industrial specifications are explicitly requested.

Part Context

This part belongs to the FT24C04A/08A/16A series of serial EEPROMs from Fremont Micro Devices Ltd. These devices utilize advanced CMOS technology to reduce power consumption compared to older NMOS serial devices. The series is designed for standard two-wire bus connections, allowing multiple units to be connected on the same bus depending on the address configuration and memory density.

Replacement Considerations

The Microchip Technology 24C04A is a functionally similar 4K-bit I2C EEPROM with comparable specifications. Verify pin compatibility and ensure the replacement supports the required 5.0V operating voltage and hardware write protection features.
