Memory IC Procurement Notes

Verify the specific suffix EM against the official datasheet to confirm package type and material compliance. Ensure the operating voltage requirements align with your system design, as this component requires a minimum of 4.5 V. Confirm availability status directly with authorized distributors, as lead times may vary based on production schedules.

Memory IC Selection Notes

Select this component when a Microwire interface is preferred over SPI or I2C for legacy compatibility. It is suitable for applications requiring moderate speed and low pin count. Consider the 14-SOIC package size for PCB layout constraints. Verify that the 4.5 V minimum supply voltage meets your system's power rail specifications before integration.

Memory IC Part Context

This part belongs to the NM93CS series of serial EEPROMs from onsemi. These devices are designed for general-purpose non-volatile memory applications. The series typically offers various capacities and interface options to suit different embedded system needs. The NM93CS46EM specifically targets 1-kbit storage requirements with Microwire connectivity.

Memory IC Replacement Considerations

Check for direct cross-reference part numbers from onsemi or other manufacturers offering compatible Microwire EEPROMs. Ensure substitute parts match the 14-SOIC package and 4.5-5.5 V operating voltage range. Verify pinout compatibility to avoid redesigning the PCB layout during replacement.
