FT24C04A-USR-T

Overview

The FT24C04A-USR-T is a 4Kbit (512 x 8) serial EEPROM manufactured by Fremont Micro Devices Ltd. It operates on a supply voltage of 1.8V to 5.5V and supports I2C bus frequencies up to 1 MHz at 5V or 400 kHz at lower voltages. The device features a self-timed write cycle of 5ms maximum, hardware write protection via the WP pin, and an industrial operating temperature range of -40°C to 85°C. It is housed in an 8-pin SOP package.

Feature Summary

• Supports standard two-wire bi-directional serial interface with Schmitt trigger inputs for noise filtering
• Includes hardware data protection through a dedicated write protect pin
• Enables partial page write operations within a 16-byte page structure

Applications

• Low power consumer electronics requiring non-volatile storage
• Industrial control systems needing reliable parameter retention
• IoT devices utilizing I2C communication protocols

Procurement Notes

Verify that the ordering suffix matches the required package type and tape-and-reel configuration. Confirm RoHS compliance status if environmental regulations apply. Ensure the specific revision level aligns with design requirements before finalizing procurement orders.

Selection Notes

Select this component when a 4Kbit capacity is sufficient for application needs. Consider the 1.8V to 5.5V wide voltage range for flexible power supply designs. Verify that the SOP-8 package footprint fits the available PCB space constraints.

Part Context

This part belongs to the FT24C04A/08A/16A series of serial EEPROMs from Fremont Micro Devices. The series utilizes advanced CMOS technology for low power consumption. The USR-T designation specifically indicates the SOP-8 package variant supplied in tape and reel format.

FAQ

How many devices can be connected on the same I2C bus?

Four FT24C04A devices can be wired-OR on the same bus using the A2 and A1 address pins.

What is the function of the NC pin?

The NC pin is a No-Connect pin and should not be utilized in the circuit design.
