Memory IC Procurement Notes

Verify that the specific ordering suffix 'SN16KVAO' corresponds to the 8-Lead SOIC package and Automotive Extended temperature grade as defined in the official datasheet. Confirm RoHS compliance status and ensure the component matches the exact manufacturer part number before integration into production schedules.

Memory IC Selection Notes

Select this component when an I2C-compatible EEPROM with automotive qualification is required. Ensure the system voltage remains within the 2.5V to 5.5V range. Consider the 64-byte page write buffer size for write efficiency and verify that the 8-SOIC package dimensions fit the target PCB layout constraints.

Memory IC Part Context

This part belongs to the 24XX256 family of 256-Kbit Serial EEPROMs manufactured by Microchip Technology. The family includes variants like the 24AA256 and 24FC256, which differ primarily in operating voltage ranges and maximum clock speeds. The 24LC256 variant specifically targets standard voltage applications requiring robust serial interface performance.

Memory IC Replacement Considerations

Cross-reference with other 24LC256 variants such as 24LC256-I/SN for industrial temperature grades or 24LC256-E/MS for MSOP packages if physical footprint changes are permissible.
