FT24C02A-UTG-T

Overview

The FT24C02A-UTG-T 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 1.8V. 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. Key electrical parameters include a typical standby current of less than 1µA, a write cycle time of 5ms maximum, and an endurance rating of 1,000,000 cycles. It utilizes a TSSOP-8 package.

Feature Summary

• Supports standard two-wire bi-directional serial interface compatible with I²C bus modes.
• Includes hardware write protection via the WP pin to prevent unauthorized programming.
• Features automatic erase before write operation and self-timed internal programming cycles.
• Provides noise protection through Schmitt trigger filtered inputs on all pins.

Applications

• Data storage in low power consumer electronics
• Configuration memory for microcontroller systems
• Parameter logging in industrial monitoring devices

Procurement Notes

Verify that the ordering suffix matches the required package type and lead-free status. Confirm the specific version requirements regarding address pin availability, as the U-series provides full pin access compared to the 5xx variant. Ensure compatibility with the target system's I²C bus voltage levels and timing constraints before finalizing procurement orders.

Selection Notes

Select this component when a complete 8-pin configuration is necessary for multi-device I²C bus applications, distinguishing it from the limited 5-pin 5xx versions. Consider the wide operating voltage range and industrial temperature specifications for robust performance in varying environmental conditions. Evaluate the page write capabilities for efficient data handling in memory-intensive designs.

FAQ

What is the difference between the FT24C02A-5xx and FT24C02A-Uxx versions?

The FT24C02A-5xx version has only 5 valid pins and is suitable for single-device applications where multiple EEPROMs cannot share the same I²C bus. The FT24C02A-Uxx version provides 8 valid pins, making it suitable for all applications, including those requiring multiple devices on the same bus.

How does the Write Protect (WP) pin function?

The WP pin protects the entire EEPROM array from programming operations. Programming is allowed if the WP pin is left unconnected or connected to VIL. All programming functions are disabled if the WP pin is connected to VIH or VCC, while read operations remain unaffected.
