Memory IC Procurement Notes

Verify the specific suffix 'AVM8X' against official Fairchild or onsemi documentation to confirm exact package dimensions and tape-and-reel specifications. Confirm RoHS compliance status as older manufacturing runs may vary. Ensure the source document explicitly lists this full part number to avoid confusion with similar variants like NM93C56LVM8X.

Memory IC Selection Notes

Select this component when a 128-word by 16-bit organization is required for non-volatile storage. It is suitable for designs needing low power consumption during standby modes. Verify that the system voltage falls within the 2.7V to 5.5V operating range. Ensure the PCB layout accommodates the 8-pin SOIC package constraints.

Memory IC Part Context

This device belongs to the NM93C56 series of serial EEPROMs manufactured by Fairchild Semiconductor, now part of onsemi. The series is designed for applications requiring reliable, low-power data storage with a simple serial interface. The Microwire protocol allows for efficient communication with host processors using minimal I/O pins.

Memory IC Replacement Considerations

Check for direct pin-compatible substitutes such as FM93CS56M8X or CAT93C56L if sourcing from different manufacturers. Verify that any replacement maintains the same 128x16 bit organization and Microwire interface compatibility.
