FT24C04A-USG-B

Overview

The FT24C04A-USG-B is a 4Kbit (512 x 8) serial EEPROM manufactured by Fremont Micro Devices Ltd. It utilizes an I2C-compatible two-wire serial interface and operates within a supply voltage range of 1.8V to 5.5V. The device supports clock frequencies up to 1 MHz at 5V and 400 kHz at lower voltages, featuring Schmitt trigger inputs for noise protection. It includes hardware write protection via the WP pin, allows partial page writes, and provides automatic erase before write operations.

Feature Summary

• Supports standard two-wire bi-directional serial interface with Schmitt trigger filtered inputs
• Features hardware write protection pin to prevent accidental programming
• Enables self-timed internal programming with automatic erase before write
• Allows partial page write operations within the 16-byte page structure

Applications

• Low power portable electronic devices requiring non-volatile data storage
• Industrial control systems operating in extended temperature ranges
• Embedded microcontroller applications needing configuration parameter retention
• Smart metering and utility equipment requiring long-term data retention

Procurement Notes

Verify package type matches the 'B' suffix indicating tube packaging. Confirm RoHS compliance status as indicated by the 'G' option. Ensure ordering specifications align with industrial temperature requirements. Cross-reference datasheet revision DS3001M for accurate electrical characteristics. Validate availability through authorized distributors as stock levels fluctuate.

Selection Notes

Select this component when a 4Kbit capacity is required with low standby current consumption. Consider the 1.8V minimum supply voltage for battery-operated designs. Verify that the SOP-8 package fits the PCB layout constraints. Check if the specific bus address pins A2 and A1 meet system addressing needs. Evaluate endurance requirements against the typical one million cycle specification.

Part Context

This part belongs to the FT24C04A/08A/16A series of serial EEPROMs from Fremont Micro Devices. The series shares common architecture but differs in memory density. The USG variant specifically denotes a Green Package option in SOP-8 format. It serves as a direct functional replacement for legacy 24C04 devices in many applications.

Replacement Considerations

FT24C04A-ENR-T is listed as a parameter equivalent substitute.
