FT24C04A-KTG-T

Overview

The FT24C04A-KTG-T is a 4Kbit (512 x 8) serial Electrically Erasable PROM manufactured by Fremont Micro Devices Ltd. It utilizes a standard two-wire I2C compatible interface for data transfer, supporting clock frequencies up to 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 features an 8-lead TSOP package. Key electrical parameters include a maximum standby current of less than 1µA, a write cycle time of 5ms maximum, and an access time of 550 ns. It is designed for industrial temperature ranges from -40°C to +85°C.

Feature Summary

• Supports standard two-wire bi-directional serial interface with Schmitt trigger inputs for noise protection
• Features hardware write protect capability via dedicated pin for data security
• Includes automatic erase before write operation and self-timed write cycles
• Offers high reliability with typical one million cycle endurance and extended data retention

Applications

• Data storage in industrial control systems requiring non-volatile memory
• Configuration parameter storage in consumer electronics devices
• Calibration data retention in automotive instrumentation modules

Procurement Notes

Verify the specific suffix 'KTG' against official Fremont Micro Devices documentation to confirm package type and tape/reel specifications. Ensure compatibility with existing PCB footprints, as TSOP packages differ physically from DFN or SOP variants within the same series. Confirm voltage and temperature ratings match system requirements before procurement.

Selection Notes

Select this component when a low-power, I2C-compatible EEPROM is required for applications needing 4Kbit capacity. Consider the 1.8V to 5.5V operating range for flexibility in various power supply environments. Evaluate the TSOP package suitability against available board space and assembly constraints compared to other package options like DFN or SOT-23.

Part Context

This part belongs to the FT24C04A/08A/16A series of serial EEPROMs from Fremont Micro Devices. These devices are fabricated using advanced CMOS technology for low power consumption. The series shares common interface protocols and functional characteristics, differing primarily in memory density and physical package configurations such as DIP, SOP, TSSOP, DFN, MSOP, and SOT-23.

Replacement Considerations

FT24C04A-UNR-T is listed as a parameter-equivalent substitute. Verify pinout and package dimensions before substitution. Other industry equivalents like AT24C04A or M24C04 may require voltage level or timing verification.
