FT24C04A-UMR-B

Overview

The FT24C04A-UMR-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 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 an access time of 550 ns. It utilizes an 8-pin MSOP surface-mount package and functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Supports standard two-wire bi-directional serial interface compatible with I²C protocols
• Includes hardware write protection via the WP pin for data security
• Features low standby current consumption suitable for power-sensitive applications
• Provides high reliability with significant endurance cycles and long-term data retention

Applications

• Consumer electronics requiring non-volatile parameter storage
• Industrial control systems needing reliable data logging
• Automotive modules utilizing robust memory solutions
• Portable devices operating on limited power supplies

Procurement Notes

Verify the specific ordering suffix 'UMR-B' against official manufacturer documentation to confirm the exact package type, RoHS compliance status, and tube packaging configuration. Ensure compatibility with your system's voltage levels and I²C bus requirements before finalizing procurement decisions.

Selection Notes

Select this component when a compact 4K-bit EEPROM is required in an 8-lead MSOP package. It is suitable for designs needing hardware write protection and operation across a wide voltage spectrum. Consider alternative packages if different form factors are preferred for the same memory capacity.

Part Context

This part belongs to the FT24C04A/08A/16A series of Two-Wire Serial EEPROMs. The series shares common architectural features including the I²C interface and write protection mechanisms. Variations exist primarily in memory density and physical package options, allowing designers to scale storage while maintaining interface consistency.

Replacement Considerations

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