FT24C02A-KTG-T

Overview

The FT24C02A-KTG-T is a 2048-bit serial Electrically Erasable and Programmable Read-Only Memory (EEPROM) manufactured by Fremont Micro Devices Ltd. It features an I2C-compatible two-wire serial interface for data access. The device operates within a supply voltage range of 1.8V to 5.5V and supports industrial temperature ranges from -40°C to +85°C. It offers low standby current consumption, page write capabilities, and hardware write protection.

Feature Summary

• Supports standard two-wire serial interface for simplified system integration
• Provides hardware write protection to prevent accidental data modification
• Features low power consumption with minimal standby current requirements
• Includes input noise protection via Schmitt triggers and filtering

Applications

• Industrial control systems requiring non-volatile parameter storage
• Consumer electronics needing configuration data retention
• Automotive subsystems operating in harsh thermal environments
• Smart meters storing calibration constants and usage logs

Procurement Notes

Verify the specific suffix 'KTG' against official Fremont Micro Devices documentation to confirm package type and tape-and-reel specifications. Ensure the component meets required automotive or industrial qualification standards if applicable to your design. Cross-reference pinouts with similar variants like USG or ULR to avoid assembly errors due to packaging differences.

Selection Notes

Select this component when a small, non-volatile memory solution is needed for storing device settings or calibration data. It is suitable for designs constrained by space and power, leveraging its low voltage operation and compact footprint. Consider alternatives only if higher density or different interface protocols are required.

Part Context

This EEPROM belongs to the FT24CxxA series, designed for cost-effective data storage in embedded applications. It complements microcontrollers by providing persistent storage for critical parameters that must survive power cycles. The series is widely used in scenarios where reliability and low power are prioritized over high-speed data throughput.

Replacement Considerations

Compatible substitutes include M24C02-W/R and AT24C02B. Verify voltage ranges and package dimensions before substitution. Ensure the replacement supports the same I2C addressing scheme and write cycle endurance requirements.
