FT24C04A-USG-T

Overview

The FT24C04A-USG-T is a 4Kbit (512 x 8) serial EEPROM manufactured by Fremont Micro Devices Ltd. It features an I2C-compatible two-wire 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, with a maximum standby current of 1 µA. It utilizes an 8-pin SOP package and includes hardware write protection via the WP pin.

Feature Summary

• Supports 16-byte page write operations with partial page write capability.
• Includes a dedicated Write Protect (WP) pin for hardware data protection.
• Features Schmitt trigger inputs with filtering for noise immunity.
• Provides automatic erase before write functionality.

Applications

• Low power consumer electronics
• Industrial control systems
• Smart metering devices

Procurement Notes

Verify that the specific USG suffix corresponds to the Green Package SOP-8 variant in tape and reel packaging as indicated in the order code table. Confirm RoHS compliance status matches project requirements. Ensure the ordering suffix aligns exactly with the datasheet specifications to avoid functional or physical discrepancies.

Selection Notes

Select this component when a 4Kbit capacity is required alongside a standard 8-pin surface mount footprint. The wide voltage range accommodates various logic levels. Consider alternative packages like DFN or SOT-23 if board space constraints necessitate smaller form factors within the same series.

Part Context

This part belongs to the FT24C04A/08A/16A series of serial EEPROMs from Fremont Micro Devices. The series shares common architectural features including the I2C interface and low-power CMOS technology. The USG suffix specifically denotes the SOP-8 package configuration with green compliant materials.
