FT24C02A-UTR-B

Overview

The FT24C02A-UTR-B is a 2Kb (256 x 8) serial EEPROM manufactured by Fremont Micro Devices Ltd. It features 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 industrial temperatures from -40°C to +85°C. Key electrical parameters include a 5ms write cycle time, less than 1µA standby current, and 1 million write cycle endurance. It is housed in an 8-pin TSSOP package.

Feature Summary

• Supports standard two-wire bi-directional serial interface for data transfer
• Includes hardware write protection via dedicated pin to prevent accidental modification
• Enables efficient data storage through 16-byte page write mode capability

Applications

• Data logging systems requiring non-volatile memory retention
• Configuration storage for embedded microcontrollers
• Calibration parameter preservation in industrial sensors

Procurement Notes

Verify the specific ordering suffix 'B' corresponds to tube packaging as defined in the manufacturer's order code table. Confirm that the RoHS compliant option matches project requirements. Ensure the selected package variant aligns with the PCB footprint design constraints before finalizing procurement orders.

Selection Notes

Select this component when a full complement of eight address pins is required for multi-device bus configurations. The U-series designation indicates suitability for all application types compared to the limited five-pin versions. Verify that the operating voltage range covers the system's minimum supply levels to ensure reliable operation across the entire temperature spectrum.

Part Context

This part belongs to the FT24C02A family of serial electrically erasable programmable read-only memories. The series utilizes advanced CMOS technology to achieve low power consumption. The specific model represents the industry-standard 2Kbit capacity variant designed for general-purpose data storage applications in consumer and industrial electronics.

FAQ

How does the WP pin function?

Connecting the Write Protect (WP) pin to VCC disables all programming functions, protecting the memory array from writes while allowing read operations.

What is the difference between the 5xx and Uxx versions?

The 5xx version has only five valid pins and restricts bus usage to one device per bus, whereas the Uxx version provides eight valid pins suitable for multiple devices on the same bus.
