FM24C03UFLZMT8X

Memory IC Overview

The FM24C03UFLZMT8X is a 2Kbit (256 x 8) CMOS non-volatile serial EEPROM manufactured by Fairchild Semiconductor. It operates within the Standard I2C 2-wire bus protocol, supporting clock frequencies up to 400 kHz with a typical access time of 900 ns. The device is housed in an 8-TSSOP package measuring 4.40 mm in width. It features hardware write protection via the WP pin and offers data retention of at least 40 years with endurance of 1,000,000 write/erase cycles.

Memory IC Feature Summary

• Conforms to Standard I2C 2-wire bus protocol for synchronous data transfer between master and slave devices using SCL and SDA lines.
• Provides hardware write protection capability allowing selective locking of memory sections by connecting the WP pin to VCC or VSS.
• Designed to minimize pin count and simplify printed circuit board layout requirements through compact integration.

Memory IC Applications

• Microcontroller-based systems requiring non-volatile data storage
• Industrial control units needing reliable parameter retention
• Consumer electronics with limited space for component placement

Memory IC Procurement Notes

Verify the specific suffix MT8X corresponds to the TSSOP-8 tape and reel packaging configuration required for automated assembly processes. Confirm that the lead-free status aligns with current environmental compliance standards for your manufacturing region. Ensure the voltage supply range matches your system's logic levels before finalizing procurement orders.

Memory IC Selection Notes

Select this component when a 2Kbit capacity is sufficient for application needs and standard I2C compatibility is required. The TSSOP-8 package is suitable for designs prioritizing space efficiency over through-hole mounting. Consider the 400 kHz speed limit if higher throughput is necessary, as faster alternatives exist within the broader EEPROM family.

Memory IC Part Context

This part belongs to the FM24C03 series of serial EEPROMs from Fairchild Semiconductor. It shares architectural similarities with other members like the FM24C16U and FM24C32U but differs in memory density and address decoding logic. The series is characterized by its robustness in industrial environments and compatibility with standard I2C controllers.

Memory IC Replacement Considerations

Direct substitutes include other 2Kbit I2C EEPROMs from compatible manufacturers such as Microchip's 24LC02 series. Verify pinout compatibility and voltage specifications before swapping. Alternative packages like SOIC-8 may require adapter solutions if footprint changes are unavoidable.
