FT24C04A-KLR-T

Overview

The FT24C04A-KLR-T is a 4Kb (512 x 8) serial EEPROM manufactured by Fremont Micro Devices Ltd. It features an I²C interface with a maximum clock frequency of 1 MHz and an access time of 550 ns. The device operates on a single supply voltage ranging from 1.8V to 5.5V and supports byte and page write operations within a 5 ms cycle time. It is housed in a 5-pin SOT-23 package, suitable for surface mount installation, and functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Supports standard I²C bus communication protocols for efficient data transfer
• Provides non-volatile storage capability to retain data without power
• Includes hardware write protection functionality to prevent accidental data modification

Applications

• Embedded systems requiring configuration parameter storage
• Low-power battery-operated electronic devices
• Industrial control units needing reliable data retention

Procurement Notes

Verify the specific suffix 'KLR' corresponds to the SOT-23-5 package variant when sourcing. Confirm that the manufacturer Fremont Micro Devices Ltd is the authorized supplier for this part number. Ensure compatibility with the target system's I²C voltage levels and timing requirements before finalizing procurement decisions.

Selection Notes

Select this component for designs requiring compact surface-mount packaging and low-voltage operation down to 1.8V. It is appropriate for applications where moderate storage density is needed alongside high-speed I²C communication. Consider the 550 ns access time for performance-critical interfaces.
