FT24C02A-UTG-B

Overview

The FT24C02A-UTG-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 an industrial temperature range of -40°C to +85°C. It utilizes an 8-pin TSSOP package and includes hardware write protection via the WP pin.

Feature Summary

• Supports standard two-wire bi-directional serial interface for data transfer.
• Includes hardware write protection pin to prevent accidental programming.
• Features low standby current consumption for power-efficient applications.

Applications

• Data storage in industrial control systems
• Configuration memory for embedded devices
• Parameter logging in sensor networks

Procurement Notes

Verify the specific ordering suffix 'B' corresponds to tube packaging as defined in the manufacturer's order code table. Confirm that the component meets RoHS compliance requirements if necessary for your assembly process. Ensure the selected variant matches the required package type and temperature rating for your design specifications.

Selection Notes

Select this component when a 2Kb non-volatile memory solution is required with I²C connectivity. The Uxx version provides all eight pins, making it suitable for designs requiring multiple devices on the same bus or full address pin access. Consider the 1.8V minimum operating voltage for low-power system integration.

Part Context

This part belongs to the FT24C02A series of serial EEPROMs from Fremont Micro Devices. The series offers various package options including DIP, SOIC, TSSOP, DFN, and SOT-23. The FT24C02A-UTG-B specifically denotes the TSSOP-8 package with green (RoHS compliant) lead finish supplied in tubes.

FAQ

What is the function of the WP pin?

The Write Protect (WP) pin disables all programming functions when connected to VCC or VIH, protecting the memory array from unintended writes while allowing read operations.

How does the FT24C02A-UTG-B differ from the -5xx version?

The -Uxx version like the UTG-B has 8 valid pins, allowing for full device addressing and use in systems with multiple EEPROMs on the same bus, whereas the -5xx version has only 5 valid pins.
