FT24C02A-KTR-T

Overview

The FT24C02A-KTR-T is a 2Kbit (256 x 8) serial EEPROM manufactured by Fremont Micro Devices Ltd. It features an I2C interface with a maximum clock frequency of 1MHz at 2.5V to 5.5V and 400kHz at 1.8V. The device operates within a voltage range of 1.8V to 5.5V and supports an industrial temperature range of -40°C to +85°C. Key electrical parameters include a typical read access time of 900ns, a write cycle time of 5ms, and a standby current of 1uA. It offers high reliability with 1,000,000 write endurance cycles and 100-year data retention.

Feature Summary

• Supports standard two-wire bidirectional serial communication via the I2C interface.
• Includes hardware data protection mechanisms to prevent unauthorized writes.
• Features automatic erase-before-write operations for efficient data management.
• Capable of partial page write operations within its 16-byte page structure.

Applications

• Industrial control systems requiring persistent parameter storage
• Consumer electronics needing configuration data retention
• Embedded devices utilizing low-voltage power supplies

Procurement Notes

Verify the specific suffix KTR-T against official datasheets to confirm the TSSOP-8 package and tape-and-reel packaging format. Ensure compatibility with system voltage levels between 1.8V and 5.5V. Confirm that the I2C address configuration meets design requirements. Check for RoHS3 compliance if required by regional regulations. Validate that the operating temperature range of -40°C to +85°C suits the target environment.

Selection Notes

Select this component when a small, non-volatile memory solution is needed for storing calibration data or user settings in space-constrained designs. The 2Kbit capacity is suitable for applications requiring minimal storage without complex addressing schemes. Consider the 1.8V minimum operating voltage for battery-powered or low-power systems. The I2C interface simplifies PCB routing compared to parallel memory options.

Part Context

This part belongs to the FT24C02A series of serial EEPROMs from Fremont Micro Devices Ltd. It shares architectural similarities with other members like the FT24C02A-FPR-T but differs in package type, using TSSOP-8 instead of SOT-23-5. The series is designed for general-purpose data storage in embedded applications where power efficiency and interface simplicity are prioritized over high-speed bulk data transfer.
