FT24C02A-UTR-T

Overview

The FT24C02A-UTR-T is a 2Kb (256 x 8) serial EEPROM manufactured by Fremont Micro Devices Ltd. It operates within a supply voltage range of 1.8V to 5.5V and supports an industrial temperature range of -40°C to +85°C. The device utilizes a standard two-wire I2C interface with a maximum clock frequency of 1 MHz at 5V and 400 kHz at lower voltages. Access time is specified at 550 ns, with a write cycle time of 5 ms. It features hardware write protection via the WP pin, 16-byte page write capability, and high endurance of 1,000,000 write cycles. The component is housed in an 8-pin TSSOP package.

Feature Summary

• Supports low voltage operation from 1.8V to 5.5V with standby current under 1µA.
• Includes a dedicated Write Protect (WP) pin for hardware data protection.
• Enables efficient data writing through 16-byte page write mode and partial page operations.
• Features Schmitt trigger inputs and noise filtering for signal stability.

Applications

• Data logging systems requiring non-volatile storage
• Configuration memory for embedded controllers
• Parameter storage in industrial instrumentation

Procurement Notes

Verify that the ordering suffix 'UTR' corresponds to the TSSOP-8 package and tape-and-reel packaging format as defined in the manufacturer's order code table. Confirm RoHS compliance status if required by specific assembly processes. Ensure the design accommodates the 8-pin TSSOP footprint dimensions provided in the datasheet outline drawings.

Selection Notes

Select this part when an 8-pin surface-mount solution is preferred over the 5-pin alternative. The 'U' prefix indicates eight valid address pins, allowing multiple devices on a single I2C bus, unlike the '5xx' version. This variant is suitable for applications requiring higher density addressing or flexible bus topology compared to cost-reduced versions.

Part Context

This component belongs to the FT24C02A family of 2Kb serial EEPROMs. The 'U' designation distinguishes it from the '5xx' series by providing full address pin accessibility. The 'T' suffix denotes tape-and-reel packaging, while 'R' indicates RoHS compliance. It shares core electrical specifications with other packages like SOP and DIP but differs in physical form factor.

FAQ

How does the WP pin function?

Connecting the WP pin to VCC disables all programming functions, protecting the memory array. Read operations remain unaffected regardless of the WP pin state.

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

The Uxx version has 8 valid pins suitable for all applications, including multiple devices on one bus. The 5xx version has only 5 valid pins and is limited to single-device bus configurations.
