FT24C02A-KSR-T

Overview

The FT24C02A-KSR-T is a serial electrically erasable and programmable read-only memory (EEPROM) manufactured by Fremont Micro Devices Ltd. It provides a storage capacity of 2048 bits, organized as 256 words by 8 bits. The device utilizes a two-wire serial interface compatible with I2C protocols. It supports operation at a maximum clock frequency of 1 MHz and functions within a supply voltage range of 1.8V to 5.5V. The component is housed in an SOT-23-5 package and operates across a temperature range of -40°C to +85°C.

Feature Summary

• Serial electrical erasable and programmable read-only memory architecture
• Two-wire serial interface compatibility
• Wide operating supply voltage range
• High-speed synchronous operation capability

Applications

• Data logging systems requiring non-volatile storage
• Configuration parameter storage in embedded controllers
• Calibration data retention for sensor modules

Procurement Notes

Verify the manufacturer designation carefully, as FT24C series components are frequently produced by multiple foundries including Fremont Micro Devices and FMD. Confirm that the specific suffix matches the required package type and voltage specifications. Ensure the source document explicitly identifies the part as a 2K-bit EEPROM to avoid confusion with other densities in the family.

Selection Notes

Select this component when a compact SOT-23-5 footprint is required for low-capacity non-volatile storage. It is suitable for applications needing fast write cycles and broad voltage compatibility. Consider alternative pinouts if the system design mandates different package constraints or higher density requirements beyond the 2K-bit limit.

Part Context

This component belongs to the FT24CxxA family of serial EEPROMs. These devices are designed for general-purpose data storage where power-down retention is critical. The family typically includes variants with different capacities such as 4K, 8K, and 16K bits, sharing similar interface characteristics but differing in organization and address space.

Replacement Considerations

Compatible substitutes include the FT24C04A-ULR-T and FT24C08A-UDG-B from the same manufacturer family. Cross-reference with standard I2C EEPROMs like the AT24C02 or M24C02, ensuring voltage levels and package dimensions align with the existing design constraints.
