FT24C04A-KSG-T

Overview

The FT24C04A-KSG-T is a 4Kbit (512 x 8) serial EEPROM manufactured by Fremont Micro Devices Ltd. It utilizes an I²C interface with a maximum clock frequency of 1 MHz at 5V and 400 kHz at lower voltages. The device operates within a supply voltage range of 1.8V to 5.5V and supports page write modes with a self-timed write cycle of 5ms maximum. It features hardware write protection, Schmitt trigger inputs for noise filtering, and high reliability with 1 million write cycles and 100-year data retention. The component is housed in an 8-MSOP package and functions across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Supports standard two-wire bi-directional serial interface compatible with I²C bus modes up to 1 MHz.
• Includes hardware write protect pin for data security and Schmitt trigger filtered inputs for noise protection.
• Features low power consumption with standby current typically below 1µA and internal organization for byte or page writes.

Applications

• Data storage in battery-powered consumer electronics requiring low standby current
• Configuration parameter storage in industrial control systems operating in wide temperature ranges
• Device identification and calibration data retention in automotive-grade applications

Procurement Notes

Verify the specific suffix 'KSG' against the manufacturer's official ordering code documentation to confirm the exact package type and tape/reel specifications. Ensure compatibility with existing PCB footprints for the designated MSOP variant. Confirm RoHS3 compliance status if required by regional regulations. Cross-reference lead times and availability directly with authorized distributors as stock levels fluctuate.

Selection Notes

Select this component when a 4Kbit non-volatile memory solution is required with I²C connectivity and operation down to 1.8V. It is suitable for designs needing hardware write protection and high endurance. Compare against M24C04 variants for voltage range differences; the FT24C04A supports 1.8V start-up unlike the standard 2.5V M24C04-W. Consider package constraints as the KSG suffix denotes a specific surface-mount form factor.

Part Context
