Memory IC Procurement Notes

Verify the specific package type associated with the suffix 'CUM' against official Microchip documentation, as standard listings often reference SOIC or TSSOP variants. Confirm RoHS compliance status and ensure the ordering quantity matches the manufacturer's specified tape and reel or cut tape requirements. Cross-reference the datasheet revision to guarantee compatibility with your system design.

Memory IC Selection Notes

Select this component when a 4-Kbit capacity is required within an I²C network. Ensure the operating voltage range of 1.7V to 5.5V aligns with the host controller's supply rails. Consider the industrial temperature grade if the application environment exceeds standard commercial limits. Verify that the available packages fit the PCB layout constraints.

Memory IC Part Context

This part belongs to the AT24C04C/AT24C08C family of serial EEPROMs designed for low-power and low-voltage operations. The series offers flexibility through various package options including SOIC, TSSOP, UDFN, and SOT23. It is optimized for applications where space saving and energy efficiency are critical priorities.

Memory IC Replacement Considerations

Direct replacements include other AT24C04C variants with different package suffixes such as AT24C04C-SSHM-T or AT24C04C-STUM-T. Ensure the substitute maintains the same memory organization and interface compatibility.
