FT24C02A-USR-T

Overview

The FT24C02A-USR-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 industrial temperatures from -40°C to 85°C. Packaged in an 8-SOP, it includes hardware write protection via the WP pin and offers typical endurance of 1,000,000 write cycles.

Feature Summary

• Supports standard two-wire bi-directional serial interface compatible with I²C bus modes.
• Includes dedicated Write Protect (WP) pin for hardware data protection against programming.
• Features Schmitt trigger inputs with filtering for enhanced noise immunity.
• Provides automatic erase before write operation and self-timed internal programming cycles.

Applications

• Low power consumer electronics requiring non-volatile storage
• Industrial control systems operating in extended temperature ranges
• Embedded devices utilizing multi-device I²C bus architectures

Procurement Notes

Verify that the ordering suffix 'USR' corresponds specifically to the SOP-8 package variant as defined in the manufacturer's order code table. Confirm RoHS compliance status matches project requirements. Ensure the component source aligns with the specified Fremont Micro Devices Ltd manufacturing origin to guarantee datasheet parameter accuracy.

Selection Notes

Select this model when an 8-pin surface-mount solution is required for I²C communication. The USR suffix indicates the SOP-8 package, which differs from TSSOP or DFN options. This version provides all eight valid pins, making it suitable for applications requiring multiple EEPROMs on a single bus compared to the five-pin variants.

Part Context

This component belongs to the FT24C02A series of 2Kb serial EEPROMs. The 'U' designation identifies the eight-pin version capable of supporting multiple devices on one bus, unlike the '5' series. The 'S' indicates the SOIC/SOP package style, while 'R' denotes tape and reel packaging. It shares core electrical specifications with other package variations in the family.

FAQ

How does the FT24C02A-USR-T handle multiple devices on the same bus?

Unlike the five-pin versions, the USR-T utilizes three address pins (A2, A1, A0), allowing up to eight devices to be addressed on a single I²C bus.

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 accidental writes while leaving read operations unaffected.
