FT24C02A-KLR-T

Overview

The FT24C02A-KLR-T is a 2Kb (256 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 a write cycle time of 5 ms per word or page. The device offers an access time of 550 ns and operates within a supply voltage range of 1.8V to 5.5V. Designed for surface mount installation, it is available in an SOT-23-5 package. The component supports operation across a temperature range of -40°C to 85°C and complies with RoHS3 specifications.

Feature Summary

• Non-volatile memory storage utilizing EEPROM technology
• I²C bus interface supporting standard and fast modes
• Hardware write protection capabilities for the memory array

Applications

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

Procurement Notes

Verify the specific suffix KLR against official Fremont Micro Devices Ltd documentation to confirm the SOT-23-5 package variant. Ensure compatibility with system voltage levels between 1.8V and 5.5V. Confirm that the 1 MHz I²C clock speed meets the controller's timing requirements. Check for RoHS3 compliance if required by project specifications.

Selection Notes

Select this component when a compact SOT-23-5 footprint is required for low-capacity non-volatile storage. It serves as a suitable alternative to larger packages like TSSOP-8 when board space is constrained. Consider the 1.8V minimum operating voltage for low-power applications. Verify that the 2Kb capacity aligns with the specific data retention needs of the design.

Part Context

This part belongs to the FT24C02 series of serial EEPROMs from Fremont Micro Devices Ltd. The series provides electrically erasable programmable memory organized in various capacities. The FT24C02A-KLR-T specifically denotes the 2Kb density variant housed in a five-pin surface-mount package, distinguishing it from eight-pin versions like the FT24C02A-KTR-T.

Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include FT24C02A-5LR-T, FT24C02A-FLR-T, and FT24C02A-FPR-T from Fremont Micro Devices Ltd. Cross-manufacturer alternatives such as the S-24C02DI-M5T1U5 from ABLIC Inc. are also documented as equivalent options.
