23LC1024-I/SN Pinout

Package: SOIC-8

Notes

Pin numbering could not be determined. The source material provides pin names and functions but no Pin Number column and no pin diagram image was attached. Pin numbers are set to "?" for all rows. To obtain the correct pin assignments, consult the SOIC-8 package diagram in the full datasheet or contact the manufacturer. The pin order in this table does not reflect actual pin positions on the device.

Note 1: This parameter is periodically sampled and not 100% tested.
