NM24C03LEM8X

Memory IC Overview

The NM24C03LEM8X is a 2K-bit (256 x 8) CMOS serial EEPROM manufactured by Fairchild Semiconductor. It features an I2C/2-Wire serial interface for data communication between a master processor and the slave device. The component is housed in an 8-pin SOIC package. It supports synchronous clocking via SCL and SDA lines, conforms to the Standard IIC 2-wire protocol, and includes hardware write protection capabilities for the upper half of memory.

Memory IC Feature Summary

• Supports standard I2C 2-wire bus protocol with dedicated clock and data lines
• Provides hardware write protection for the upper memory half via the WP pin
• Utilizes CMOS technology for low power consumption and non-volatile storage

Memory IC Applications

• Small-area networks requiring cost-efficient memory solutions
• Automotive electronic systems
• Consumer audio equipment such as stereos
• Television sets and other scaled-down consumer electronics

Memory IC Procurement Notes

Verify the specific suffix 'LEM8X' against official Fairchild documentation to confirm package type and lead-free status. Ensure compatibility with the Standard IIC protocol requirements for your system design. Confirm that the 256-byte capacity meets your application's storage needs before procurement.

Memory IC Selection Notes

Select this component when a small, non-volatile memory solution is required for I2C-based systems. It is suitable for applications where board space is limited and low pin count packaging is preferred. Consider the write protection feature if secure storage for specific data segments is necessary.

Memory IC Part Context

This part belongs to the NM24C series of serial EEPROMs designed by Fairchild Semiconductor. These devices are engineered to minimize pin counts and simplify printed circuit board layout. The series offers various memory sizes while maintaining compatibility with the Inter-Integrated Circuit (IIC) bus standards.

Memory IC Replacement Considerations

Check for direct equivalents within the NM24C02/03 family or cross-reference with other manufacturers offering 2K-bit I2C EEPROMs in SOIC-8 packages. Verify electrical specifications and pinout compatibility before substitution.
