FT24C04A-EMR-B

Overview

The FT24C04A-EMR-B is a 4K-bit (512 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 I2C bus clock frequencies up to 1 MHz at 5V, or 400 kHz at lower voltages. The device features a self-timed write cycle with a maximum duration of 5 ms and includes hardware write protection via the WP pin. It is housed in an 8-pin SOP package and functions reliably across an industrial temperature range of -40°C to 85°C.

Feature Summary

• Supports standard two-wire bi-directional serial interface compatible with I2C protocols
• Includes hardware write protection pin for data security
• Features low power operation with standby current typically below 1 µA
• Provides high reliability with guaranteed endurance cycles

Applications

• Industrial control systems requiring non-volatile data storage
• Consumer electronics utilizing low voltage logic levels
• Embedded microcontroller applications needing parameter retention

Procurement Notes

Verify that the specific ordering suffix matches the required package type and RoHS compliance status. Confirm the manufacturer source directly with Fremont Micro Devices Ltd or authorized distributors to ensure authenticity. Check for any recent product change notices regarding packaging or specifications before finalizing procurement orders.

Selection Notes

Select this component when a 4K-bit capacity is sufficient for application requirements. Ensure the design accommodates the 16-byte page write limitation and utilizes the available address pins A2 and A1 for bus configuration. Verify that the operating voltage aligns with the system's 1.8V to 5.5V range and that the SOP package fits the PCB layout constraints.
