Notes

Pin numbering could not be determined from the source material. The provided text table contains pin names and functions but no Pin Number column, and no pin diagram image was attached. To obtain the correct pin-to-number mapping for the SOIC-8 package, consult the package diagram or pinout diagram in the full datasheet. The pin names listed above are accurate for the 23LC1024-I/SN variant; they must be matched to physical pin positions (1–8) using the official package drawing.
